PSA-ACT Complex (PSA) Protein

MyBioSource producer and supplier of purified PSA-ACT Complex antigen as a prostate tumor marker for medical research and clinical biomedical manufacturing.

Custom preparations, technical support, bulk quantities and aliquoting available.

Free-PSA has a molecular weight of 28 kDa and a pI of 6.2-6.5, while PSA-ACT molecular weight is 90 kDa (PSA 28KDa and ACT 60-65KDa). Prostate Specific Antigen PSA is localized in cytoplasm of prostate acinar cells, ductal epithelium and seminal fluid.

Prostate Specific Antigen PSA exists in 3 major forms; free PSA, PSA-ACT (PSA bound to Alpha-1 Antichymotrypsin) and PSA-A2M (PSA bound to Alpha-2 Macroglobulin). Serum concentration as a free to bound ratio correlates well with tumour mass and clinical stage of prostate cancer. High levels of free PSA can also be seen in serum from patients with benign hypertrophy.

Small volumes of PSA-ACT Complex protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS173182 is a protein targeting PSA-ACT Complex. Also known as PSA-ACT Complex, Human - High Purity.
