Overview

KRAS is a small GTPase implicated in various biological processes, such as cell proliferation, cell survival, and cell metabolism. This proto-oncogene is well known to be mutated in many cancer subtypes, inducing an uncontrolled proliferation and cell metabolism modifications. It thereby contributes to the Warburg effect in cancer cells. Like the majority of small GTPase, KRAS binds to GDP in its inactive form or binds to GTP to switch into the active form. KRAS G12C is one of the most commonly represented mutant forms in cancer, which leads to a permanently active state of KRAS. The Ras guanine nucleotide exchange factor, also called SOS1, is a GEF protein promoting the active form of KRAS. The upregulation of the KRAS / SOS1 interaction leads to cancer phenotypes. Identifying new KRAS/SOS1 inhibitors or GTP competitors are therefore the two major strategies to control biological processes involved in cancer growth, by reducing the KRAS activity as well as the associated pathways.

Formats

  • Our 500 assay point kit allows you to run 500 wells in 96-well or 384-well format, using a 20 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 20 µL reaction volume (5 µL of sample).

Feature:

  • No-wash steps, no separation steps
  • ELISA alternative technology
  • Sensitive detection
  • 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.

Data Sheet

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.
