Our Anti-Synapsin I (Ser603) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Synapsin I (Ser603) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of rat cortical lysate showing specific immunolabeling of the ~78 kDa synapsin I phosphorylated at Ser603 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).

Synapsin I (Ser603)
Synapsin I plays a key role in synaptic plasticity in brain (Feng et al., 2002; Nayak et al., 1996). This effect is due in large part to the ability of the synapsins to regulate the availability of synaptic vesicles for release. The role of synapsin in synaptic plasticity and in synaptogenesis regulated by phosphorylation (Jovanovic et al., 2001; Kao et al., 2002). Serine 603 is the site on synapsin I that is phosphorylated by calcium calmodulin kinase II and by p21-activated kinases (Sakurada et al., 2002; Czernik et al., 1987). Phosphorylation of this site is thought to regulate synaptic vesicle function (Nayak et al., 1996; Bahler and Greengard, 1987; McGuinness et al., 1989).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser603 of rat synapsin, 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 ~78 kDa synapsin I doublet phosphorylated at Ser603 . Immunolabeling is completely eliminated by treatment with λ-phosphatase.
