Gαs抗体(12)是一种IgG1κ小鼠单克隆Gαs抗体(也称为Gαs抗体或G蛋白亚基GNAS抗体),可通过WB和IP检测小鼠、大鼠和人类的Gαs。Gαs抗体(12)有偶联和非偶联两种形式的抗Gαs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个都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),而产生一种或多种细胞内信使的效应器(例如,腺苷酸环化酶)则较少。在哺乳动物中,G蛋白α、β和γ多肽分别由至少16、4和7个基因编码。由于这些蛋白质结合并水解GTP,并且最明显地调节了研究最深入的效应器的活性,因此人们对G蛋白的兴趣主要集中在它们的α亚基上。然而,有证据表明,βγ亚基具有重要的调节作用。Gα亚基的Gs亚家族包括两种密切相关的蛋白质,Gαs和Gαolf,它们分别刺激腺苷酸环化酶并介导对嗅觉刺激的反应。

Does this antibody react with zebrafish Gαs? If not experimentally validated, what is the predicted reactivity against the zebrafish protein?

Asked by: Lulu97
Thank you for your question. Based on our tests with this product, Anti-Gα s Antibody (12): sc-135914 is only recommended for detection of Gα s of mouse, rat and human origin by WB and IP. We do not have any internal data to support reactivity in samples from zebrafish.

Hi, Is this MAb specific for Gα-s? because the description of MAb for Gα-olf says, it can recognize both forms s and olf and in our study, we need to identify which one of the two is involved, so specificity is very necessary.

Asked by: ASM25
Thank you for your question. The antibody was raised against amino acids 11-21 of G s of human origin. The exact binding region of this antibody within the antigen has not been mapped. This antibody has not been tested experimentally for potential cross-reactivity under denaturing conditions in a Western Blot or native conditions in IP against different proteins. You might want to align the antigen sequence against the protein form of interest in order to determine potential reactivity. based on the antigen sequence we do not expect relevant cross-reactivity against G -olf. Please contact our Technical Service by phone or email or by Live Chat if you have any further questions.

For Western Blot, is it recommended to use denatured or non-denatured conditions with this antibody?

Asked by: TinTin
Thank you for your question. We recommend this antibody for use in denatured Western Blot conditions. It has not been validated for use in non-denatured conditions. Please contact our Technical Service Department for further details or inquiries.

Can you recommend a positive control to use with Gα s (12): sc-135914 for Western blot?

Asked by: TinTin
We recommend Jurkat Whole Cell Lysate (sc-2204) or rat or mouse brain tissue extract (sc-2392 or sc-2253) as positive controls as we have Western blot data showing specific detection of Gα s in these samples.
