Discover our extensive collection of research-grade antibodies,
rigorously validated for in vivo applications.
Precisely identify antibody-specific signals using matched isotype controls optimised for in vivo experimentation.
BiosimilarsInvestigate biological therapeutic mechanisms with cost-effective, research-grade biosimilar antibodies.
This non-therapeutic biosimilar has the same variable regions as Sintilimab (ideal for research). Sintilimab, a humanized IgG4κ mAb with S228P mutation, binds PD-1 (CD279), shows higher affinity than nivolumab/pembrolizumab, and cross-reacts with cynomolgus monkey PD-1. PD-1/PD-L1 regulates immune homeostasis; cancers exploit this pathway. Anti-PD-1 (e.g., sintilimab) transiently arrests tumor growth in responsive models.
