About Biosimilar Antibodies

This collection brings together research-grade recombinant antibodies (and receptor-trap fusion proteins) that reproduce the antigen-binding specificity of clinically important reference biologics — anti-TNF, anti-VEGF, anti-PD-1/PD-L1, anti-HER2, anti-CD20 and many more. Each reagent binds the same target as its reference drug, so it can serve as a positive control, a functional blocking/neutralizing tool, a binding reagent, and a reference standard in pharmacokinetic (PK) and anti-drug-antibody (ADA) bioanalysis. All products are For Research Use Only (RUO) and are not the licensed therapeutic products.

Choosing how to work with a reference biologic: three complementary reagents

A biosimilar research antibody is one of three reagents used to study or measure a biologic drug. They are complementary, not interchangeable — most immunogenicity and PK workflows use all three.

Dimension	Biosimilar antibody (this collection)	Anti-idiotypic antibody	PK / ADA ELISA kit
What it is	Recombinant copy of the drug's variable region	Antibody raised against the drug's paratope/idiotype	Ready-to-run immunoassay
What it binds	The drug's antigen (e.g. TNF-α, PD-1, HER2)	The reference/biosimilar drug itself	The drug, or anti-drug antibodies, in a sample
Primary use	Positive control, blocking/neutralization, binding reagent	Capture or detect the drug; ADA bridging assays	Quantify drug level (PK) or immunogenicity (ADA)
Reads out	Binding & function (ELISA, SPR/BLI, flow, neutralization)	Drug concentration when paired in an assay	Concentration from a standard curve
Best for	Assay development, functional studies, controls	Building a custom PK or ADA assay	Routine sample quantification
Format	Purified protein (mAb, Fab, fusion or ADC)	Purified antibody	Microplate kit

How to read this: Use the biosimilar antibody as your positive control and functional tool. To measure the drug in samples, pair it with an anti-idiotypic antibody to build a PK or ADA assay, or use a ready-made ELISA kit for routine quantification. If you are characterizing binding or blocking activity, start here; if you are quantifying drug or anti-drug-antibody levels, add the matching kit.
