Our Anti-Beclin1 (Ser295) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Beclin1 (Ser295) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of wild type (WT) beclin-1 expressed in HeLa cell lysate showing specific immunolabeling of beclin-1 phosphorylated at Ser295. This immunolabeling is eliminated in the beclin-1 alanine substitution mutant (S295A: Mut) expressed in HeLa cell lysate.
Beclin-1 plays a key role in tumor suppression and autophagy. It has been suggested that autophagy proteins such as beclin-1 can inhibit tumorigenesis and that decreased expression of these proteins may contribute to the development of human malignancies (Liang et al., 1999). Akt-mediated phosphorylation of beclin-1 at Ser-295 has been shown to decrease autophagy and promote oncogenesis (Wang et al., 2012).

WB
Rabbit
BECN1
60 kDa
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser295 of human beclin-1, conjugated to keyhole limpet hemocyanin (KLH).
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Liquid
Prepared from rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
WB: 1:250
Unconjugated
Specific for endogenous levels of the ~60 kDa beclin1 protein phosphorylated at Ser295. Immunolabeling of the beclin-1 band is eliminated in the beclin-1 alanine substitution mutant.
