p-p53抗体(B-3)是一种IgG1κ小鼠单克隆p-p53抗体(也称为TP53抗体),可通过WB、IP、IF、IHC(P)和ELISA检测人源Thr 55磷酸化的p53。p-p53抗体(B-3)既可作为非偶联抗p-p53抗体形式,也可作为多种偶联形式的抗p-p53抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。p53是一种含有DNA结合、寡聚化域和转录激活域的肿瘤抑制因子,可上调生长停滞和凋亡相关基因以响应应激信号,从而影响程序性细胞死亡、细胞分化和细胞周期控制机制。p53定位于细胞核,但可由负调节因子MDM2陪伴至细胞质,MDM2是一种E3泛素连接酶,在活性p53存在时上调,其中MDM2使p53多泛素化以靶向蛋白酶体。在没有DNA的情况下,p53可以组装成四聚体,在潜伏和活性(DNA结合)构象之间波动,并通过包括磷酸化和乙酰化在内的翻译后修饰进行差异激活。p53的DNA结合域(DBD)(氨基酸110-286)中的突变会损害与顺式元件的能量有利关联,并涉及几种人类癌症。p53在残基Thr 155处的磷酸化由COP9信号小体(CSN)介导,并将p53靶向泛素-26S蛋白酶体依赖性降解。

Hello, We are conducting a western blot using fibroblast cells and we are using the p-p53 antibodies (B-3): sc-377553 to detect phosphorylated p53 (Thr 55). We were wondering what size the bands show up as since we don't really detect 50 kDa bands.

Asked by: Anonymous
Thank you for your question. The expected molecular weight of p-p53 is 53 kDa. If issues in your experiment persist, please reach out to our technical service team for direct troubleshooting assistance.

This antibody (sc-377553) seems to recognize a higher band than predicted (around 90 kDa vs 55 kDa). I was wondering if you could comment on that. Other antibodies against P-p53 seem to detect a protein around 55 kDa.

What application is the blocking peptide sc-377553 P appropriate for?

Asked by: TinTin
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.

Rated 3 out of 5 by jylang from 抗体的非特异信号多我们使用这个抗体做western 实验,实验结果显示背景特别高,主带信号弱,杂带很多。尽管我们使用了BSA 作为封闭剂,且封闭2个小时,但是杂带还是很多。

Rated 3 out of 5 by Abreporter from an OK antibody for WBThis antibody works for WB (1:500 dilution, 40 ug HeLa Lysate), although the signal intensity is low (and also with a higher background). However, we used frozen cell lysates and have not tested fresh samples.
