    Product Information

    Product Description

    This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 555 fluorescent dye and tested in-house for direct immunofluorescent analysis in human cells and mouse tissues. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Ras (E4K9L) Rabbit mAb #91054.

    Product Usage Information

    Application Dilution
    Immunofluorescence (Frozen) 1:50 - 1:200
    Immunofluorescence (Immunocytochemistry) 1:100 - 1:200

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Protocol

    Specificity / Sensitivity

    Ras (E4K9L) Rabbit mAb (Alexa Fluor® 555 Conjugate) detects endogenous levels of total K-Ras, H-Ras, and N-Ras proteins.

    Species Reactivity:

    Human, Mouse, Rat, Monkey

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu37 of human K-Ras protein.

    Background

    The 21 kDa guanine-nucleotide binding proteins (K-Ras, H-Ras, and N-Ras) cycle between active (GTP-bound) and inactive (GDP-bound) forms (1). Receptor tyrosine kinases and G protein-coupled receptors activate Ras, which then stimulates the Raf-MEK-MAPK pathway (2-4). GTPase-activating proteins (GAPs) normally facilitate the inactivation of Ras. However, research studies have shown that in 30% of human tumors, point mutations in Ras prevent the GAP-mediated inhibition of this pathway (5). The most common oncogenic Ras mutation found in tumors is Gly12 to Asp12 (G12D), which prevents Ras inactivation, possibly by increasing the overall rigidity of the protein (5,6).
