At ambient temperature. Upon receipt, store the product at the temperature recommended below.


Store lyophilized protein at -80°C. Lyophilized protein remains stable until the expiry date when stored at -80°C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at -80°C for long term storage. Reconstituted protein can be stored at 4°C for a week.

Quality Control Test

BCA to determine quantity of the protein.
SDS PAGE to determine purity of the protein. LAL to determine quantity of endotoxin.


Research topic



PSP94BP (PSPBP, Peptidase inhibitor 16, CRISP-9, PI-16) is a cell-surface-expressed type II transmembrane serine protease and was identified as one of the most highly upregulated genes in prostate cancer. PSP94BP protein expression was highest at sites of bone metastasis and in late-stage primary tumor, suggesting a role in tumor progression. In accordance, in vivo studies demonstrated that overexpression of PSP94BP led to tumor progression and metastasis. As PSP94BP expression correlates well with prostate cancer progression, it was proposed as a diagnostic marker and target for prostate cancer therapy.
