Description
Alpha smooth muscle actin (α-SMA) is a one of six actin isoforms involved in smooth muscle contraction and is often used as a marker of myofibroblast formation. Myofibroblasts are characterized by de novo expression of α-SMA, which is incorporated into actin stress fibers and confers a high contractile activity to the cells. Chronic tissue injury leads to persistent de novo formation of myofibroblasts (α-SMA+), excessive contraction, and deposition of ECM, eventually leading to tissue fibrosis.
Formats:
Our HV (100 assay point) kits allow you to run 100 wells in 96-well format, using a 100 µL reaction volume (10 µL of sample).
Our 500 assay point kit allows you to run 500 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).
Our 5,000 assay point kit allows you to run 5,000 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).

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.
