GM130 (C-terminal region) (clone M342), anti-human, mouse, rat

Background:
Golgi Matrix Protein (GM130) is a peripheral cytoplasmic protein that is bound to Golgi membranes. It maintains cis-Golgi structure, and it regulates the disassembly and reassembly of the Golgi complex during mitosis. GM130 may also be important during docking and fusion of coatomer (COPI) coated vesicles to the Golgi membrane. The carboxy-terminal domain of GM130 is highly homologous to the human auto-antigen, golgin-95. GM130 interacts in a GTP-dependent manner with Rab1b protein, a regulator of anterograde traffic between ER and Golgi membranes. It has also been implicated in the activation of Ste-kinase, YSK1, during the golgi reorganization that occurs along with cell migration.

Immunogen: Clone M342 was generated from a recombinant protein corresponding to amino acid residues in the C-terminal region of human GM130. This sequence has high homology to similar regions in rat and mouse GM130.

Specificity: This antibody detects a 130 kDa* protein corresponding to the apparent molecular mass of GM130 on SDS-PAGE immunoblots of mouse C2C12 cells. In immunocytochemistry, anti-GM130 specifically stains Golgi in mouse C2C12 cells.

Buffer/Storage:
Mouse monoclonal purified with protein A chromatography is supplied in 100µl phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. Store at –20°C. Stable for 1 year.
