      DescriptionMILLIPLEX MAP Ras-Raf Oncoprotein Magnetic Bead Panel 6-Plex - Cell Signaling Multiplex Assay
      OverviewRas proteins are GTPases encoded by three genes: HRAS, KRAS, and NRAS. The protein products of these genes exhibit a high degree of sequence identity and are regulated by a conserved mechanism: exchange of GDP for GTP switches the Ras protein into an active conformation. In its GTP-bound state, Ras has high affinity for its downstream effectors, including the Raf family of protein kinases (ARAF, BRAF, and CRAF/RAF1). Raf proteins, in turn, signal through MEK to activate the MAPK pathway. In healthy cells, Ras activation is a transient response to extracellular growth stimuli and is restricted by the rapid conversion of Ras-GTP back to Ras-GDP. However, the Ras-Raf-MEK pathway is often aberrantly activated in cancer. Mutations in the RAS genes are amongst the most frequently encountered oncogenic events, occurring in ~25% of human cancers, with mutations altering the 12th amino acid (glycine) being particularly prevalent. These driver mutations maintain Ras in a constitutively active, GTP-bound state. Additionally, certain cancers feature KRAS gene amplification, although the effects of gene amplification on protein expression are not yet well-characterized.

      The MILLIPLEX® MAP 6-plex Ras-Raf Oncoprotein Magnetic Bead Kit (Cat. No. 48-684MAG) is a premixed kit to be used for the simultaneous quantification of the following 6 protein analytes:

      • pBRAF (Ser446)
      • pCRAF (Ser338)
      • pMEK1 (Ser217/Ser221)
      • Ras (total)
      • Mutant Ras protein, RasG12D*
      • Mutant Ras protein, RasG12V*
      *Detects H-Ras, N-Ras, and K-Ras protein

      Panel TypeCell Signaling
      ApplicationIntracellular Bead-Based Multiplex Assays using the Luminex technology enable the simultaneous relative quantitation of multiple phosphorylation and total pathway proteins in tissue and cell lysate samples. Compare Multiplexing results to those of Western blotting.
      Key Applications
      • Multiplexing
      Application Notes• An overnight (4°C) incubation is recommended for best results.
      • This kit must be run using Assay Buffer 2 (provided).
      • This assay requires 25 µL diluted cell lysate per well.
      • The suggested working range of protein concentration for the assay is 1 to 25 µg of total protein/well (25 μL/well at 40 to 1,000 µg/mL).
      Biological Information
      SpecificityCross-reactivity between the antibodies and any of the other analytes in this panel is non-detectable or negligible.
