RAB3A Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemistry was performed on paraffin-embedded carcinoma of human prostate tissue. To expose target proteins, heat-induced epitope retrieval by 1mM EDTA in 10mM Tris buffer (pH8.5) at 120°C for 3 min. Following antigen retrieval, tissues were probed with a RAB3A monoclonal antibody (Product # MA5-27178) at a dilution of 1:150.

RAB3A Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemistry was performed on paraffin-embedded carcinoma of human pancreas tissue. To expose target proteins, heat-induced epitope retrieval by 1mM EDTA in 10mM Tris buffer (pH8.5) at 120°C for 3 min. Following antigen retrieval, tissues were probed with a RAB3A monoclonal antibody (Product # MA5-27178) at a dilution of 1:150.

RAB3A Antibody in Western Blot (WB) — Western blot was performed using Anti-RAB3A Mouse Monoclonal Antibody (OTI5C12) (Product # MA5-27178) and a 25 kDa band corresponding to RAB3A was observed across tissues tested except Rat kidney and Rat liver. Whole cell extracts (30 µg lysate) of Mouse brain (Lane 1), Rat brain (Lane 2), Rat kidney (Lane 3) and Rat liver (Lane 4) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0321BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence Goat anti-Mouse IgG (H+L), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

RAB3A Antibody — Antibody specificity was demonstrated by detection of differential basal expression of the target across tissue tested owing to their inherent genetic constitution. Relative expression of RAB3A was observed in Mouse brain, Rat brain in comparison to Rat kidney and Rat liver using Anti-RAB3A Mouse Monoclonal Antibody (OTI5C12) (Product # MA5-27178) in Western Blot. {RE}

Target Information

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