Product Overview
Clone IOF-18 is a rabbit monoclonal antibody that recognizes RAF proto-oncogene serine/threonine-protein kinase (gene RAF1) phosphorylated at Ser621 in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 73.1 kDa, and the supplier reports an observed band at about 73 kDa.
RAF1 (c-Raf) is a serine/threonine kinase that passes signals from active Ras to MEK1/2 and then ERK1/2, a cascade that shapes proliferation, differentiation and survival. Its activity is controlled by phosphorylation at several regulatory residues, and it is studied widely in growth-factor signaling and in Ras-driven cancers.

Immunogen
Synthetic phosphopeptide around Ser621 of human raf1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places RAF proto-oncogene serine/threonine-protein kinase in the cytoplasm, cell membrane, mitochondrion and nucleus. Tissue expression noted by UniProt (human): In skeletal muscle, isoform 1 is more abundant than isoform 2. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
