Gα i-3抗体(H-7)是一种IgG3 κ小鼠单克隆Gα i-3抗体(也称为Gα i-3抗体或G蛋白亚基GNAI3抗体),可通过WB、IP、IF和ELISA检测小鼠、大鼠和人类来源的Gα i-1和Gα i-3。Gα i-3抗体(H-7)既有偶联形式也有非偶联形式的抗Gα i-3抗体。异源三聚体G蛋白的功能是将信息从细胞表面受体传递到细胞内效应器。非常广泛的受体中的每一种都能特异性地检测细胞外刺激(光子、信息素、气味剂、激素或神经递质),而效应器(即腺苷酸环化酶)则通过产生一种或多种细胞内信使来发挥作用,其数量较少。在哺乳动物中,G蛋白的α、β和γ亚基分别由至少16、4和7个基因编码。对G蛋白的研究主要集中在其α亚基上,因为这些蛋白能够结合并水解GTP,并最明显地调节研究最深入的效应器的活性。已经鉴定出四种不同的Gα亚基类别;这些包括Gs、Gi、Gq和Gα 12/13。Gi类包括所有已知的易受百日咳毒素修饰的α亚基,包括Gα i-1、Gα i-2、Gα i-3、Gα o、Gα t1、Gα t2、Gα z和Gα gust。其中,三种Ga i亚型的功能是打开心房钾通道。

Does this antibody work well in Raw 264.7 and Jurkat cell lines?

Asked by: little star123
Thank you for your question. We do not currently have any data with this antibody in either of these cell lines.

How likely is it that this antibody will show a cross reaction to Gnai2 since they are similar in structure? Was this tested? How similar is the immunogen the antibody was raised against to Gnai2? Thanks in advance!

Asked by: Gwen
Thank you for your question. This mouse monoclonal antibody, Gα i-3 (H-7): sc-365422, is specific for an epitope mapping between amino acids 339-354 at the C-terminus of Gα i-3 of rat origin. This region does share significant identity (80%) with the Gα i-2 protein, so there is potential of cross-reactivity. Unfortunately, this cross-reactivity has not yet been tested. For a limited time, we are offering a free sample of this antibody. Please contact our Technical Service Department if you would like to request a sample. Please call our European Support office toll-free at 00800 4573 8000, email [email protected], or contact us by live chat.

What application is the blocking peptide sc-365422 P appropriate for?

Asked by: Germaine
Thank you for your question. The blocking peptide is intended for use as a negative control, by pre-adsorbing the mouse monoclonal antibody against the antigen. For full protocol details, please contact our Technical Services Department or view our online protocol here: https://www.scbt.com/scbt/resources/protocols/peptide-neutralization
