Upgraded! Anti-Idiotypic Antibody Services

An anti-idiotypic antibody (anti-ID Ab, see the schematic diagram) binds to the idiotype of another antibody, usually an antibody drug. An idiotype can be defined as the specific combination of idiotopes present within an antibodies complement determining regions. Since anti-ID Abs are capable of binding to antibody drugs within biological fluids, they are commonly used in preclinical setting for

Pharmacokinetic analysis of antibodies

(PK) and pharmacodynamics (PD). Due to the similarity between anti-ID Abs and anti-drug antibodies, anti-ID Abs are also commonly used as a reference standard for antibody drug immunogenicity, anti-drug antibody (ADA) studies and neutralization antibody measurement.

ProBio has experience in developing of highly sensitive and specific polyclonal and monoclonal anti-ID Abs to support your antibody drug development. We try to work as closely as possible with our customers to understand their specific downstream application in order to generate their perfect anti-ID. See our case studies »

Anti-Idiotypic Antibodies

Type	1. Antigen-blocking	2. Non-blocking	3. Complex-specific
Schematic diagram
Feature	Paratope-specific	Not Paratope-specific	Partially paratope-specific
Antigen binding	Inhibitory	Not inhibitory	Not inhibitory
Application	Detect free drug only	Detect total drug (free and bound)	Detect bound drug typically
Selection Guideline	Type 1 or type 2 could be applied to detect antibody drug when having a cell-bound drug target e.g. PD1/PDL1 Type 1 & type 2 may both be needed when having a secret drug target e.g. TNF
