p53(A-1)抗体是一种IgG1 kappa轻链小鼠单克隆抗体,也称为TP53,可通过蛋白质印迹、免疫沉淀、免疫荧光和酶联免疫吸附检测小鼠、大鼠和人源p53蛋白质。p53单克隆抗体(A-1)可作为抗p53抗体的非偶联形式,以及多种偶联形式的抗p53抗体(A-1),包括琼脂糖,辣根过氧化物酶,藻红蛋白,异硫氰酸荧光素,和多种Alexa Fluor®偶联物。p53蛋白质由人类TP53基因编码,是一种重要的肿瘤抑制因子,在维持基因组稳定性方面发挥着重要作用。作为转录因子,p53可调节细胞周期停止、DNA修复、细胞凋亡和衰老等基本细胞过程中相关基因的表达。一旦检测到DNA损伤,p53可在G1/S检查点诱导细胞周期停止,以便在复制开始之前有时间进行修复。如果损伤无法修复,p53会启动细胞凋亡,以消除潜在的有害细胞,防止突变传播。p53的活性通过翻译后修饰(如磷酸化作用、乙酰化作用和泛素化作用)受到严格调控,这些修饰会影响其稳定性和功能。MDM2是一种关键的负调控因子,可通过泛素-蛋白酶体途径促进p53的降解作用。TP53基因突变在人类癌症中约占50%,是癌症中最常见的突变基因之一。这些突变通常发生在p53的DNA结合域,导致其抑制肿瘤的能力丧失。一些突变形式不仅失去了保护功能,还获得了促进肿瘤发展的致癌特性。了解p53的结构域、转激活结构域、DNA 结合结构域和寡聚结构域至关重要,因为每个结构域都对 p53 的功能至关重要。对 p53 的研究对癌症治疗具有重大意义,其策略旨在通过开发小分子来恢复p53在肿瘤中的正常功能,或抑制其负调控因子(如 MDM2)的负调控作用。p53基因敲除小鼠等动物模型以及p53小鼠单克隆抗体(A-1)等p53抗体,通过提供有关细胞应激反应和肿瘤抑制机制的宝贵见解,有助于我们全面了解该蛋白质的功能和重要性。

Can you recommend a negative control to use with p53 (A-1): sc-393031 monoclonal antibody?

Asked by: jenni
We recommend using the blocking peptide sc-393031 P as a negative control. Antibody binding to antigen may be blocked/competed by pre-absorption with the blocking peptide. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/peptide-neutralization
