Anti-Idiotypic Antibodies

Anti-idiotypic antibodies are essential reagents for PK and ADA assays to support pre-clinical and clinical trial studies for a new biologic or biosimilar.

Whether to support your regulatory applications, biosimilar development, or research studies on biologics, off-the-shelf anti-idiotypic antibodies (anti-IDs) will help you achieve your outcome faster.

Bio-Rad offers an extensive range of anti-IDs, with more than 150 products, one of the largest on the market.

The downloadable infographic highlights the ten key reasons why Bio-Rad's anti-idiotypic antibodies are market-leaders.

Ten Reasons to Choose Bio-Rad

Ten Reasons to Choose Bio-Rad’s Anti-Idiotypic Antibodies

1. You receive a performance guarantee.


All our antibodies are extensively tested for suitability in their stated applications.

2. You are provided with in depth scientific data for each antibody.


Our antibodies come with a wealth of experimental data spanning specificity testing to inhibition assays and bridging assay examples in human serum background.

3. You know the affinity of each antibody.


Affinities are measured using the monovalent Fab format, ensuring the reported values describe truly intrinsic affinities. Affinities are typically very high (sub-nanomolar), ensuring sensitive detection in serum. You will find control antibodies for ADA antibodies, with varying affinities to suit your needs.

4. You get more than just the vial.


Every antibody has protocols to help you get started.

5. You will find unique type 3 antibodies.


Type 3 (drug-target complex) antibodies enable robust, specific, and sensitive PK assays without the need to develop a bridging assay. Our technology enables the selection of these rare specificities.

6. You have peace of mind with recombinant monoclonal antibodies.


All our antibodies are sequence defined and cannot be lost. They are human in sequence and developed using animal-free technology.

7. You can find antibodies for non-antibody biologics.


For example, anti-IDs for Fc-fusion biologics such as belatacept.

8. You don’t need to conjugate yourself.


Save your time for the important stuff. Anti-idiotypic antibodies are available in HRP-labeled versions and are ready to use immediately in your assays.

9. You can choose from an expansive range of products.


Bio-Rad has over 150 products to choose from and we are constantly expanding our portfolio to meet our customers’ needs.

10. You get consistent performance.


We carry out stringent quality control to ensure batch-to-batch reproducibility. We produce and compare three independent batches of each antibody to ensure consistent characteristics and shelf-life stability.
