Product Details
Synaptotagmin (Thr202)
Synaptotagmin is widely regarded as the primary calcium sensor for synaptic vesicle exocytosis (Fernandez-Chacon et al., 2001; Wang et al., 2003). Moreover, recent studies indicate that the protein also plays a key role in endocytosis (Poskanzer et al., 2003). Synaptotagmin can be phosphorylated by multiple protein kinases and this may play a key role in modulation of synaptotagmin’s ability to influence both the exocytotic and endocytotic components of synaptic transmission (Hilfiker et al., 1999; Lee et al., 2004).
Antigen Affinity Purified from Pooled Serum
Polyclonal
IgG
ICC, WB
Rabbit
SYT1
62 kDa
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr202 of rat synaptotagmin, 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 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: 1:1000
WB Brain: 1:1000
ICC: 1:400
Unconjugated
Specific for endogenous levels of the ~62 kDa synaptotagmin protein phosphorylated at Thr 202. Immunolabeling is completely eliminated by treatment with λ-phosphatase.
