PSA (human) AlphaLISA Detection Kit, 5,000 Assay Points

The AlphaLISA® Human Prostate-Specific Antigen (PSA) Detection Kit is designed for detection and quantitation of human PSA in serum, buffered solution or cell culture medium in a homogeneous (no-wash steps, no separation steps) assay. PSA is also known as Kallikrein-related peptidase 3 (KLK3).

Human prostate-specific antigen (hPSA, Kallikrein-related peptidase 3, KLK3) is a 33 kDa glycoprotein of the kallikrein family present in seminal fluids. It is a protease that seems to function in the liquefaction of semen after ejaculation, facilitating sperm migration through cervical mucus. Small amounts are normally found in the serum of healthy men, but a number of pathological conditions could increase them due to prostatic tissue damage, hence its quantitation may be helpful in the diagnosis and monitoring of prostatic carcinomas.

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

All-In-One-Well AlphaLISA Assays for Direct Biomarker Quantification in Cell Cultures

Biomarker levels were measured directly in CulturPlates-96 and-384 in a simple, fast, all-in-one-well AlphaLISA assay format. The elimination of transfer and wash steps simplifies cellular assays, reduces variability and significantly reduces hands-on time and costs associated with consumables. Integral plasma membrane (EGFR) and secreted solubleproteins (TNFa, IL1ß, IL6, IL8) were successfully determined, on adherent or suspension cells, using the standard AlphaLISA Immunoassay buffer.
