Label

PE is an oligomeric protein complex (270 kDa) from red algae that exhibits intensely bright red-orange fluorescence with excitation peak at 566 nm and an emission peak at 574 nm. The complex consists of six heterodimers, α subunit (18 kDa) and β-subunit (20 kDa), and an additional γ-subunit (34 kDa).

Background

PSMA (prostate-specific membrane antigen), also known as Folate hydrolase 1 or FOLH1, is an enzyme with folate hydrolase and peptidase activity. It is highly expressed in prostate cancer cells and is used as a diagnostic and prognostic indicator of prostate cancer. PSMA is used in the clinic as a target for PET (positron emission tomography) imaging in the detection and progression of prostate cancer, but radioactive analogs are used for the treatment of prostate cancer. It is also expressed in other tumor types and in a few normal tissues. PSMA is under extensive investigation as target for CAR-T cells and bi-specific antibodies-based cancer therapies.

Storage/Stability

At least 6 months at 4°C. Protect from prolonged exposure to light. DO NOT FREEZE. The antibody solution should be stored undiluted between 2°C and 8°C.

Assay Conditions

One million PSMA CHO cells (BPS Bioscience #79461) were blocked and stained with 1 µg of anti-PSMA antibody, PE-labeled (BPS Bioscience #101976) for 30 minutes on ice, washed three times, and analyzed by flow cytometry. PSMA CHO recombinant cells (green) were compared to parental CHO-K1 cells (blue). The Y-axis represents the cell count while the X-axis shows PE intensity.

Applications

Useful for studying expression of PSMA on the cell surface by flow cytometry. For flow cytometry staining, the suggested use for this reagent is 5 µl (1 µg antibody) per million cells in 100 µl of staining volume.

Shipping Temperature

+4°C (gel packs)

Cross Reactivity

This antibody recognizes human PSMA. It has not been tested in other species.

Warnings

Do not freeze. Protect from light.
