Research Grade Biosimilar Antibodies
EnkiLife offers 800+ research grade biosimilar antibodies produced using the same variable-region sequences as approved therapeutic antibodies. Covering targets across oncology (HER2, EGFR, PD-1/PD-L1, CD20), autoimmune disease (TNF-α, IL-6R, IL-17A), and ophthalmology (VEGF). Designed for mechanism-of-action studies, ADA/PK assay development, and preclinical pharmacology at research-grade pricing.
Access antibodies with the same variable-region sequences as approved therapeutics, at research-grade pricing. No minimum order requirements and available for immediate delivery.
Why Choose EnkiLife
📈 Same Variable Region as Originator
Produced with published CDR sequences matching the approved therapeutic — enabling direct comparison studies and reference standard development.
📊 ADA & PK Assay Development
Ideal as positive controls, calibration standards, and coating antigens in anti-drug antibody (ADA) screening and pharmacokinetic (PK) drug monitoring assays.
🎯 Broad Therapeutic Coverage
References to trastuzumab, adalimumab, pembrolizumab, nivolumab, rituximab, bevacizumab, atezolizumab, durvalumab, and 100+ other approved or pipeline therapeutics.
💰 Research-Grade Pricing
Significant cost savings compared to therapeutic-grade materials. Flexible pack sizes (from 50µg to 10mg) allow you to scale experiments without overspending.
EnkiLife Biosimilar vs. Traditional Research Antibodies
| Feature | EnkiLife Biosimilar | Traditional Hybridoma-Derived Antibodies |
|---|---|---|
| Sequence Origin | Identical V-region to approved therapeutic antibodies | Hybridoma-derived, sequence may be undefined or subject to drift |
| Production System | Recombinant, sequence-defined, lot-to-lot consistent | Hybridoma culture, batch-to-batch variability possible |
| ADA/PK Applications | Validated as positive controls, calibrators, coating antigens | Not typically validated for ADA/PK assays |
| Primary Applications | Mechanism-of-action, ADA/PK, preclinical pharmacology | In vitro detection (WB, IHC, IF, Flow) |
No royalty fees for research use. No minimum orders. Ready for immediate research use.
