详细介绍
| 货号: 26909 |
| 规格: 30 µL |
| 基因符号: RAS |
| 描述: Anti-Ras-GTP Mouse Monoclonal Antibody |
| 背景介绍: Small GTPases are a super-family of cellular signaling regulators. Ras belongs to the Ras sub-family of GTPases that regulate cell proliferation, cell motility, and gene transcription. GTP binding increases the activity of Ras, and the hydrolysis of GTP to GDP renders it inactive. GTP hydrolysis is aided by GTPase activating proteins (GAPs), while exchange of GDP for GTP is facilitated by guanine nucleotide exchange factors (GEFs). |

免疫沉淀/蛋白质印迹:  IP/WB Analysis of Active Ras Protein.Purified recombinant Ras proteins were loaded with GDP (lane 1) or GTPγS (lane 2). These proteins were immunoprecipitated with anti-Ras-GTP monoclonal antibody (Cat. # 26909). After SDS/PAGE, the membrane filter was probed with anti-Ras mouse monoclonal antibody (Cat. # 26014). |
主要用途
GTP酶是GTP/GDP结合蛋白。被细胞表面受体(GPCR)激活后, 它能调节下游效应器的功能。它可以结合GTP、水解GTP，因此在激活的GTP结合状态和非激活的GDP结合状态之间切换。它具有内在的GTP酶活性，可将GTP水解为GDP，从而使G蛋白失活。我们精心筛选的小鼠单克隆抗体能捕捉到与GTP结合的具有活性的GTP酶。它们已被用于通过免疫组织化学监测细胞和组织中 G 蛋白的活化和分布。
