PD-1 and PD-L1 pathway research solutions

Targeting the PD-1/PD-L1 axis has been a successful therapeutic strategy against several tumor types. Learn more about our highly validated reagents that can help you explore this key pathway.​

PD-1 and PD-L1 SimpleStep ELISA® kits

SimpleStep ELISA kits are one-step assays for quantification of your target protein​.

  • Validated and developed in relevant biological matrices - it will work with your sample
  • Proprietary tag instead of biotin-streptavidin to eliminate interference –compatible with cell culture supernatant
  • Optimized buffers to improve sensitivity and reduce non-specific antibody binding
