Ras GAP抗体(B4F8)是一种小鼠单克隆IgG2a kappa轻链抗体,可通过蛋白质印迹(WB)、免疫沉淀(IP)、免疫荧光(IF)、流式细胞术(FCM)和酶联免疫吸附测定(ELISA)检测小鼠、大鼠和人源的Ras GAP蛋白。Ras GAP (B4F8) 抗体有非结合型和多种结合型,包括琼脂糖、辣根过氧化物酶(HRP)、藻红蛋白(PE)、异硫氰酸荧光素(FITC)和多种 Alexa Fluor® 结合物。Ras GAP 蛋白在调节 Ras 家族 GTP 酶的活性方面发挥着关键作用,而 Ras 家族 GTP 酶在控制细胞增殖、分化及存活方面至关重要。通过促进GTP水解为GDP,Ras GAP充当Ras信号的负调控因子,从而防止可能导致肿瘤发生的细胞无序生长。Ras蛋白的突变会削弱其GTP酶活性,导致持续信号传导,引发各种癌症。Ras GAP与p21Ras相互作用可显著提高GTP水解速率,凸显其在维持细胞稳态中的重要性。此外,1型神经纤维瘤病基因(NF1)的产物已被确定为Ras的GTP酶激活蛋白,进一步说明了Ras GAP及其与其他调节GTP酶活性的蛋白之间的相互作用所涉及的复杂调控网络。

Hello, I am interested in this antibody and am curious to know approximately what amino acid sequences in the Ras-GAP gene this antibody has affinity for? 

Asked by: MD702
Thank you for your question. The antibody was raised against the full length of human recombinant RasGAP . The sequence is proprietary but here is the Uniprot page for more information: https://www.uniprot.org/uniprotkb/P20936/entry

Can you recommend a positive control to use with Ras GAP (B4F8): sc-63 monoclonal antibody for Western blot?

Asked by: jenni
We recommend NIH/3T3 (sc-2210), A-431 (sc-2201), PANC-1 (sc-364380) or JAR (sc-2276) whole cell lysates to use as positive controls as we have Western blot data showing specific detection of Ras GAP in these cell lines.

Rated 3 out of 5 by from Protéine difficile à sortir en western blotLes bandes d'expression protéique de RASA ne sortent pas facilement en WB, et l'anticorps est légèrement sale. Il faut beaucoup laver et insister (mettre beaucoup de protéines) pour avoir un blot exploitable.
