NewEast Biosciences pioneered the research and development of the antibodies for GTPases and mutated Oncogene ten years ago. GTPases involve (1) signal transduction in response to activation of cell surface receptors, including transmembrane receptors such as those mediating taste, smell and vision, (2) protein biosynthesis at the ribosome, (3) regulation of cell differentiation, proliferation, division and movement, (4) translocation of proteins through membranes, (5) transport of vesicles within the cell, and vesicle-mediated secretion and uptake, through GTPase control of vesicle coat assembly. An oncogene is a gene that has the potential to cause cancer.
We offer three unique categories of antibodies, which (1) recognize only the active configuration of GTPase (not the inactive one), (2) mutated Oncogene (not mild type) and (3) have super affinity for cAMP and cGMP (no acetylation required). We have over one thousand peer reviewed articles cited our products.

Cat. #: 26901 |
Gene Symbol: Gnai |
Description: Anti-Gαi-GTP Mouse Monoclonal Antibody |
Background: Heterotrimeric G proteins are critical cellular signal transducers. Gαi represents one sub-family of G proteins that could mediate the inhibition of adenylyl cyclases. Other biochemical and physiological functions of Gα i proteins are being explored. |
Immunogen: Recombinant full length protein of active Gα i1 |
Applications: IP, IHC and IF (Not applicable for WB since WB denatures the GTPase) |
Recommended Dilutions: IP: 1 µg for 1~2 mg total cellular proteins IHC, IF: 1:50-1:250 |
Concentration: 1 mg/ml |
Host Species: Mouse |
Format: Liquid |

Immunoprecipitation/Western blot: Gαi activation assay. A. CHO cells were transfected with wild type Gα i1 (lanes 1 and 2) or constitutively active Gα i1-Q204L (lane 3). Cell lysates were treated with GDP(lane 1) or GTPγS (lane 3). Lysates were then incubated with an anti-active Gα i monoclonal antibody (Cat. No.26901) (top panel). The precipitated active Gα i was immunoblotted with an anti-Gα i monoclonal antibody (Cat. No. 26003). The bottom panel shows the Western blot with anti-Gα i monoclonal antibody (Cat.No. 26003) of the cell lysates. B. HEK293 cells stably expressing human m2 mAChR were treated with (lane 2) or without (lane 1)carbachol. Cell lysates were then incubated with an anti-active Gα i monoclonal antibody (Cat. No. 26901) (top panel).The precipitated active Gα i was immunoblotted with an anti-Gα i rabbit polyclonal antibody (Cat. No. 21006). The bottom panel shows the Western blot with anti-tubulin of the cell lysates. |
