Our Anti-Rabphilin 3A (Ser234) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects rat Rabphilin 3A (Ser234) and is antigen affinity purified from pooled serum. It is great for use in WB, ICC.
Western blot of rat brain lysate showing specific immunolabeling of the ~82 kDa rabphilin 3A phosphorylated at Ser234.
Rabphilin-3A is a peripheral membrane protein that binds Ca2+ and phospholipids and is attached to synaptic vesicle membranes (Geppert et al., 1994; Li et al., 1994). The expression of rabphilin 3A is reduced in an animal model of Huntington’s disease (Smith et al., 2005). Rabphilin can be phosphorylated at Ser-234 by both CAM kinase II and PKA and this phosphorylation has been suggested to regulate neuronal activity during development in a synapse-specific manner (Fykse et al., 1995; Foletti and Scheller, 2001).

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 ~82 kDa rabphilin protein phosphorylated at Ser234. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.
