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.
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.
