HSPPC-96 is a protein peptide complex consisting of a 96 kDa heat shock protein (Hsp), gp96, and an array of gp96-associated cellular peptides. Immunisation with HSPPC-96 induces T-cell specific immunity against these peptides; gp96 is not immunogenic per se. The non-covalent binding of gp96 to peptides is neither selective nor restricted to cell types. Thus, the collection of gp96-associated peptides represents the antigenic peptide pool of a cell; this is the basis of the peptide-specific immunogenicity elicited by HSPPC-96.
