Antigen/Purification: ExpandCollapse

The antigen is a peptide corresponding to amino acid residues from the N-terminal region of rat Rab 3, conjugated to keyhole limpet hemocyanin (KLH).

The antibody is  prepared from pooled rabbit serum by affinity purification via chromatography on an affinity column made with the N-terminal peptide used as antigen.

Biological Significance: ExpandCollapse

Rab proteins belong to the Ras small GTPase superfamily. The GTP-binding Rab3 subfamily has 4 known isoforms: 3A, 3B, 3C, and 3D (Schluter et al., 2004). These proteins are expressed in highest concentrations in brain and endocrine tissues and involved in regulated exocytosis of hormones and neurotransmitters (Coppola et al., 2002). Specifically, Rab3’s are thought to play a key role in presynaptic vesicle trafficking and priming (Schluter et al., 2006).


100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg BSA per ml and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

For long term storage –20° C is recommended. Stable at –20° C for at least 1 year.
