Anti-peptide Antibody Production for diagnosis

Efficiently develop anti-peptide antibodies for precise protein targeting and post-translational modification detection.

Industrial gap/problem covered

Developing anti-protein antibodies can be costly and often requires access to the target protein itself. In cases where the protein is unavailable or difficult to obtain, a more efficient approach involves identifying short peptide fragments (typically 10-20 amino acids in length) from the target protein. These short peptides can be used as haptens to generate anti-peptide antibodies. This strategy is also advantageous due to its reduced potential for cross-reactivity among structurally similar proteins. Anti-peptide antibodies are particularly useful for detecting post-translational modifications (PTMs) within target proteins.

Description

The real challenge in producing useful anti-peptide antibodies is to choose peptides that are not only antigenic but which also generate an antibody that bind to the native protein. This process demands careful consideration of various factors.

Peptides must possess inherent immunogenicity, meaning they should be recognized by the immune system and elicit the production of antibodies. Additionally, the peptide sequence should match a region of the target protein that remains exposed and accessible when the protein folds into its native conformation. To ensure the selection of optimal peptides, our peptide selection process involves evaluating each candidate antigen against numerous databases to verify its epitope specificity. This rigorous approach ultimately identifies peptides with the desired antigenicity, solubility, and potential for antibody production.
