Programmed cell death protein 1 is an inhibitory cell surface receptor involved in the regulation of T-cell function during immunity and tolerance. Upon ligand binding, inhibits T-cell effector functions in an antigen-specific manner. Possible cell death inducer, in association with other factors. [UniProt]

Titering of the recombinant PD-1 antibody may be required for optimal performance.

1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

A full length recombinant human protein was used as the immunogen for the recombinant PD-1 antibody.

Store the recombinant PD-1 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
