Applications
ApplicationG-Protein Subunit Antibody Set. Contains 10 µl of each of Anti-Giα-1, Anti-Giα-1 and Giα-2, Anti-Giα-3 and Goα, Anti-Giα-3, Anti-Gsα, Anti-Gq- and G11α, and Anti-Gβ-Subunit.
Key Applications Immunoblotting (Western Blotting)
Application NotesImmunoblotting (1:1000, all antibodies)
Application CommentsThe specificity was confirmed with lysates from separate cultures of bacteria transfected with the genes encoding each subunit. For immunoblotting: 10 µg purified plasma membranes from rat adipocytes were loaded into each lane and resolved on a 12% acrylamide mini-gel (10 cm x 10 cm). The proteins were transferred to PVDF membranes on a semi-dry blotter and blocked in low detergent blotto (5% milk protein) for 1 hr. The blots were transferred to designated vessels containing the specific antibody diluted in low detergent blotto at 1:1000. Each blot was incubated on a rocker at room temperature with its specific antibody for 2 h, followed by 4 washes with low detergent blotto. Goat anti-rabbit IgG labeled with 125I (approximately 5µCi/µg IgG) was diluted to 500,000 cpm/ml in low detergent blotto, followed by several washes to remove milk proteins. The blots were exposed to X-ray film with intensifying screens for the indicated times. Antibodies should be titrated for optimal results in individual systems.

Useful for identifying G-protein subunits.
BackgroundGTP-binding regulatory proteins (G-proteins) are heterotrimeric proteins associated with the cell membrane that functionally couple hormones to their receptor systems within the cell. These proteins link signaling pathways that regulate the synthesis of cyclic AMP, as well as other pathways, including activation of phospholipases and mobilization of intracellular calcium. The original term, inhibitory G-proteins (Gi), refers to a family of G-proteins distinguished by differences in the α-subunit of the heterotrimer. It is believed that the different Gi's serve to couple different hormone receptors to different effector systems. However, some G-proteins may not be discriminating because they appear to interact with more than one type of receptor or effector system.
