Recognizes a protein of 94kDa, which is identified as the glucose-regulated protein 94 (grp94) and also tumor rejection antigen (gp96). Gp96 shows a high degree of sequence homology with the heat shock protein 90 (hsp90). This mAb is highly specific and shows minimal cross-reaction with other members of the HSP90 family. Grps are a class of proteins unresponsive to heat shock and are induced by glucose deprivation. Gp96 has been briefly studied as a prognostic factor in breast cancer.

Store the gp96 antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
