Background information

PRAME is a pool of lyophilized peptides, consisting mainly of 15-mer sequences with 11 amino acids overlap, covering the complete sequence of the preferentially expressed antigen of melanoma (PRAME) (UniProt ID: P78395).
In vitro stimulation of antigen-specific T cells with PepTivator Peptide Pools causes the secretion of effector cytokines and the up-regulation of activation markers, which then allow the detection and isolation of antigen-specific T cells.


MACS GMP PepTivator PRAME can be used for a variety of applications, for example, in vitro stimulation of PRAME-specific CD4
and CD8
T cells for the enrichment of IFN‑gamma–secreting T cells using the CliniMACS
Cytokine Capture System (IFN-γ).
