Our Anti-Raf-1 (Ser301) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human and rat Raf-1 (Ser301) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of UV treated human Jurkat cell lysate showing specific immunolabeling of the ~74 kDa Raf-1 protein phosphorylated at Ser301 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 minutes).

The Ras pathway is a critical signal transduction cascade involved in regulating cellular proliferation, differentiation, survival, and oncogenic transformation. Members of the Raf serine/threonine kinase family are key intermediates in this cascade, functioning to relay signals from activated Ras to the downstream protein kinases MEK and ERK (Marshall, 1996). Previous studies have shown that phosphorylation is required for Raf-1 activation (Dhillon and Kolch, 2002; Chong et al., 2003). Recent work has demonstrated that phosphorylation also regulates the downregulation of Raf (Dougherty et al., 2005) with two sites participating: Ser-301 and Ser-642.
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser301 of rat Raf-1, conjugated to keyhole limpet hemocyanin (KLH).
