Overview

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).

Features:

  • No-wash steps, no separation steps
  • ELISA alternative technology
  • Sensitive detection
  • Broad sample compatibility
  • Small sample volume

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.

Application Note

Applicability of AlphaLISA Technology to a Wide Spectrum of Complex Biological Samples

Alpha (Amplified Luminescent Proximity Homogeneous Assay) technology is a bead-based, no-wash alternative to traditional ELISAs. Instead of detection with an HRP substrate, the Alpha assay signal is generated by the excitation of an Eu+-coated bead that has been conjugated to the detection antibody.

Alpha technology offers a simple, straight forward workflow. No wash needed!

  1. Add sample
  2. Add Acceptor bead mix; incubate 1 hr
  3. Add Donor beads; incubate 30 mins
  4. Read on Alpha-enable microplate reader

Download this application note to see how no-wash AlphaLISA® technology provides a more-convenient alternative to ELISA for quantitation of biomarkers in complex sample types, including tissue, serum, and plasma.

Poster

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.
