C-Terminal antibody

Antibodies are a class of proteins that bind specifically to other proteins or peptides. Antibody production is an important part of the immune response and can be used for diagnosis and treatment. Some antibodies are produced during pregnancy and breast feeding, but most are produced by plasma cells in the bone marrow. This topic focuses on a particular type of antibody called c-terminal antibodies (CTA). CTA are unique because they have a special property that allows them to detect certain types of cancer cells. C-terminal antibodies are antibodies that specifically recognize the C-terminus of proteins. They can be used to detect proteins, to study protein interactions and posttranslational modifications, to identify protein degradation pathways, and to study their roles in disease.


C-terminal antibodies are a type of monoclonal antibody. They’re named for the fact that they bind to C-terminal regions of proteins (the end of a protein), whereas N-terminal antibodies bind to N-termini (the beginning). In terms of function, they work in much the same way as other antibodies: they recognize and bind to antigens on their target cells or molecules.

In research, these proteins are used in studies involving cellular mechanisms such as cell signaling pathways and protein folding events. They can also be used as immunodiagnostics when paired with fluorescent tags or other markers so that researchers can detect them more easily under microscopes. In medicine, C-terminal antibodies have been used for everything from diagnosing diseases at early stages through detecting cancerous tissue in patients’ bodies before surgery takes place.


C-terminal antibodies are antibodies that bind to the C-terminus of a protein. The C-terminus is the end of a polypeptide chain, which can be thought of as being composed of amino acids. The last amino acid in a polypeptide chain is often referred to as its “tail,” so we can think of these antibodies as binding to this portion of our target protein (which we’ll call “X”).

C terminal antibody target

C terminal antibodies are a type of antibody that can be used to treat cancer, autoimmune diseases and infections. They’re also being studied as a potential treatment for other conditions such as cardiovascular disease and diabetes.

C terminal antibody characterization

C terminal antibodies are a class of antibodies that target the C-terminal domain (CTD) of proteins. They can be used to study protein function, as well as for therapeutic purposes. C terminal antibodies can also be developed as therapeutic agents themselves; researchers have used them to treat cancer and viral infections in mice, though clinical trials have not yet been conducted on humans.

C terminal antibody binding

C-terminal antibody binding, C-terminal antibody target, C-terminal antibody characterization and development are all important areas of research. Research into the chemical and biological properties of antibodies that bind to or target a protein molecule’s C-terminal end is important.

C terminal antibody development

A C terminal antibody, or CTAB, is a type of monoclonal antibody that binds specifically to the carboxyl terminus (C-terminus) of the target protein. This is in contrast to other types of antibodies that bind at either an N-terminus or internal site on a protein, such as those found in immunoprecipitation assays.

CTABs are often used as reagents for affinity purification and other applications requiring high specificity for their target peptides/proteins. They can also be used as probes in western blotting experiments as well as ELISA assays; however, they are less commonly used than other types due to limited availability from commercial sources (e.g., Santa Cruz Biotechnology).

C-terminal antibody target

The C-terminal antibody target is the last 20 amino acids of a protein. It’s also known as an epitope, or antigenic determinant.

C-terminal antibodies are used in immunology to study the structure of proteins and their interactions with other molecules. They can be used to identify new epitopes on a protein, determine whether they’re accessible to other molecules, or determine how they interact with those other molecules once they have been exposed

Detection methods

  • ELISA (enzyme-linked immunosorbent assay). The most common and widely used method for detecting antibodies, ELISAs are simple to perform and can be automated. They typically use a solid surface or strip that’s been coated with an antigen. When you add your sample containing the specific antibody you’re looking for, it binds to the antigen.
  • Western blotting: In this technique, proteins are separated by size before being transferred onto a membrane where they’re probed with an antibody that recognizes your target protein (i.e., the antigen). Then another antibody is used as a secondary probe to detect any positive results from the primary one–this allows researchers to determine whether there are multiple types of antibodies present in their samples!
  • Immunofluorescence: This technique involves labeling cells with fluorescently tagged antibodies so that they glow under ultraviolet light when viewed through a microscope–you can also use this method on tissues instead of cells if necessary!

How can you detect C-terminal antibodies?

For a protein to be cleaved at its C-terminus, the peptide must have a free amino group at its N-terminus. This will result in an increase in mass of this fragment by +5 Da due to addition of a methyl group (CH3) and loss of H2O during digestion.

For detection of C-terminal antibodies:

  • Digest your protein sample with trypsin or chymotrypsin
  • Add one or two drops of bromophenol blue dye solution (0.1%) before loading onto an SDS/PAGE gel for separation by electrophoresis.

C-terminal antibody specificity and validation

If you’re using C-terminal antibodies, you’ll want to make sure that the antibody is specific for its intended target. This is especially important when working with antibodies that have multiple epitopes (like biotin or FLAG).

A good way to do this is by running a western blot and comparing your results against those from an established control sample. For example, if your C-terminal antibody works well on human tissue lysates but not mouse lysates and vice versa, then it may be possible that there’s some cross reactivity between species due to similar sequences at either end of their respective proteins.

What are the advantages of using a C-terminal antibody detection kit?

The C-terminal antibody detection kit is a simple, rapid and sensitive method to detect C-terminal antibodies in serum, plasma or whole blood. The kit can be used for both research and clinical applications.

The advantages of using this kit include:

  • Ability to detect C-terminal antibodies in a variety of species including mouse, rat and rabbit.
  • Detects both recombinant and natural antibodies (including those produced by immunization).

What are the limitations of using a C-terminal antibody detection kit?

There are two main limitations of a C-terminal antibody detection kit.

  • First, the kit may not be able to detect all C-terminal antibodies. This is because some antibodies do not have a C-terminus and therefore cannot be detected by this method. For example, most monoclonal antibodies have an Fc region that extends beyond their antigen binding site (the region of the antibody that binds to antigens). Antibodies like these cannot be detected using this technique because they lack a true C-terminus; in fact, they only have one end!
  • Second, even if you are using an antibody with a true C-terminus, there is still some room for error when using these kits due to differences in structure between native proteins and recombinant ones used for detection purposes.


The C-terminal antibody is a novel antibody that can be used to detect and identify proteins. It has many applications, including disease diagnosis and treatment monitoring. The C-terminal antibody is useful because it can be used in conjunction with other antibodies to detect multiple proteins at once.

In summary, C-terminal antibodies are different from N-terminal antibodies because they have different applications, production methods and uses. They are also sometimes referred to as CTAs, which stands for C-Terminal Antibodies. These antibodies can be used in many different ways including detecting cancer cells or identifying proteins involved in inflammation. It is usually found on proteins that contain multiple domains or subunits such as antibodies, cytokines, enzymes and hormones.


Q: What is a C-terminal antibody?

C-terminal antibodies are generated by attaching a C-terminal tag to the antibody. They’re produced by attaching a C-terminal tag to the antibody, which is different from N-terminal antibodies. They can be used to detect the presence of a protein in a sample, as well as its location within cells and tissues. These antibodies have been used in many different types of research applications: for example, they’ve been employed for studying the activity of enzymes involved in signal transduction pathways and for identifying new therapeutic targets for cancer treatment.

Q: How is a C-terminal antibody different from an N-terminal antibody?

The difference between C-terminal and N-terminal antibodies is that the former has an extra amino acid at its end, which gives it a longer half-life in vivo. This makes it ideal for applications where you want your antibody to be present in your body for longer periods of time.

C terminal antibodies are also known as full length antibodies or Fabs because they have all parts of an Immunoglobulin (Ig) molecule including heavy chains, light chains and constant regions on both sides of the disulfide bond cluster (CH2).

Q: What are the applications of C-terminal antibodies?

C-terminal antibodies can be used in immunoprecipitation, which is an assay that uses antibodies bound to magnetic beads to pull out specific proteins from a sample. In this way, you can isolate certain types of cells for further study or compare how different treatments affect your cell lineages.

Q: How are C-terminal antibodies generated or produced?

C-terminal antibodies are produced by gene engineering, recombinant DNA technology, phage display technology and yeast display technology.
