p-LKB1抗体(C-1)是一种IgG2aκ小鼠单克隆p-LKB1单克隆抗体(也称为p-LKB1或STK11抗体),通过WB、IP、IF、IHC(p)和ELISA检测小鼠、大鼠和人来源的Ser 431磷酸化LKB1。p-LKB1抗体(C-1)可作为非偶联的抗p-LKB1的抗体形式,以及多种偶联形式的抗p-LKB1抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。标致综合征(PJS)是一种罕见的遗传性疾病,其特征是嘴唇黑色素细胞斑、胃肠道错构瘤性息肉和多种癌症的风险增加。LKB1(也称为STK11和PJS)已被鉴定为PJS中突变的基因。LKB1是一种433个氨基酸的丝氨酸/苏氨酸激酶,与非洲爪蟾细胞质蛋白激酶XEEK1具有强同源性,与许多其他蛋白激酶具有较弱的相似性。LKB1广泛表达,在PJS患者中发现了许多移码、缺失和剪接突变。尽管PJS患者患癌症的风险增加,但LKB1在结直肠癌、睾丸癌或乳腺癌中似乎没有发挥重要作用。p90(RSK)和cAMP依赖性蛋白激酶对LKB1在Ser431的磷酸化对LKB1抑制细胞生长至关重要。

Can the blocking peptide be used as a positive control in Western Blot?

Asked by: AbPolly
Thank you for your question. The blocking peptide, sc-271924 P, is a short synthetic peptide and is intended for use as a negative control. It is not appropriate for use as a positive control in Western Blot.

Rated 3 out of 5 by from Reasonable potency and high specificityThis monoclonal antibody was independently tested by Kinexus Bioinformatics Corporation and is recommended for Western blotting. There was weak detection of ~60 kDa LKB1 in overnight serum-starved human A431 cells treated for 5 minutes with EGF on Western blots, but no significant cross-reactivities on these blots with any off-target proteins.
