Our Anti-Munc-18 (Ser 513) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects rat Munc-18 (Ser 513) and is antigen affinity purified from pooled serum. It is great for use in WB, ICC.
Western blot of rat cortical lysate showing specific immunolabeling of the ~65 kDa Munc-18 protein phosphorylated at Ser513 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is blocked by preadsorption of the phosphopeptide used as the antigen, but not by the corresponding non-phosphopeptide (not shown).
Anti-Munc-18 (Ser 513) Antibody
Munc-18 (Ser 513)
Munc-18 (mammalian homologue of Unc-18) is a protein that is thought to be involved in regulating exocytosis due, at least in part, to it ability to bind syntaxin (Ciufo et al., 2005). Munc18-1 is a neuron-specific member of the Sec1/Munc18 protein family that binds to syntaxin1A and is thought to stabilize the complex (Liu et al., 2004). The function of Unc-18 is thought to be regulated by PKC phosphorylation of Ser-515 in C. Elegans (Sassa et al., 1996). Ser-513 is the mammalian homologue of Ser-515 in C. Elegans.
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser513 of rat Munc-18, 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.
Prepared from pooled 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 Brain: 1:1000
Specific for endogenous levels of the ~65 kDa Munc-18 protein phosphorylated at Ser513. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.
