Anti-idiotypic for CAR-T Cell Therapy Development

The idiotypic is a characteristic that all antibodies have on their variable portions. Each antibody is combination of Anti-idiotypic determinants (epitopes). Anti-idiotypic antibodies (Anti-ID), will bind to the idiotypic of another antibody. This makes them incredibly powerful tools in the development and testing of anti-idiotypic drugs.

Researchers discovered anti-idiotypic antibodies


(anti-IDs) at the very beginning of the 20th century after many years of researching. There are five types of anti-IDs currently known: a to g to e, d, and b. Anti-IDs are a popular target for researchers looking for new treatments for autoimmune diseases, cancers, and other diseases.

This review will summarize data on anti-IDs that mimic structural and functional properties (autacoids and neurotransmitters, hormones, and xenobiotics) and assess their potential medical applications.

CAR T Cell Therapy


The use of chimeric antigen receptor (CAR-T cell) to treat B cell malignancies with Chimeric antigen receptor therapy is one of the most effective applications of this pioneering technology. It allows the manipulation of certain immune cells to treat diseases.

An engineered fusion protein is a chimeric antigen receptor. Extracellular targeting domain is derived using a single-chain fragment variant (scFv), which was derived from monoclonal antibodies. It allows the CAR-T cells to recognize the antigen and bind to it. The intracellular link is provided by a hinge or spacer protein and a transmembrane domain.

T Cell Receptor

This is composed of one or more domains of T cell receptor intracellular signals and co-stimulatory chemicals and serves as a signal to stimulate activation. Gene transfer technology can be used to reprogram cells obtained from a donor or patient to express CARs. These engineered CAR-T cells are capable of proliferating and specifically targeting tumor cells to induce their death. Antibody development company can used this to eliminate and control cancer.

We develop, validate, and implement robust, accurate bioanalytical methodologies to monitor CAR-T cell persistence and verify their safety and efficacy. The initial dose of cell therapy is low. Next, you can follow in vivo cell growth and decline. Bioanalytical tests are required to determine if the cells have survived, expressed the correct markers, and expanded in vivo.

The technology platform chosen will have an impact on specificity, selectivity, and sensitivity. It is important to ensure that you have access to well-characterized reagents throughout the life of your study.

What are Common Applications of Anti-Idiotypic Antibodies?


  • Preclinical research on therapeutic antibodies 
  • Anti-drug Antibodies (ADA kit) for clinical development 
  • Studies on Pharmacokinetics ( PK kit) 
  • Assays for immunogenicity and immune response (IR) 
  • Controls for ligand binding neutralizing tests 
  • Antibody blocking assays: Controls

Antibodies to CAR-T Cell Therapy Development


You need highly specialized antibodies reagents for CAR-T or engineered TCR therapies research and development. GenScript ProBio’s custom HuCAL(r), monoclonal antibody production services can provide you with the antibodies that you require for immunophenotyping, T cell enrichment, and bioanalysis of cell therapies.

GenScript ProBio has a long history of producing anti-idiotypic antibodies, a highly specialized critical reagent. We use to check the efficiency of cell transfection percentage with plasmids. You can use this to distinguish CAR-T cells (or other cells) from patient samples by flow cytometry.
