LEF-1抗体(B-6)是一种IgG1 κ小鼠单克隆LEF-1抗体,可通过WB、IP、IF、IHC(P)和ELISA方法检测小鼠、大鼠和人源LEF-1蛋白。LEF-1抗体(B-6)既可以是非偶联的抗LEF-1抗体形式,也可以是多种偶联形式的抗LEF-1抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。TCF(T细胞因子)家族的转录因子由Wnt-1和Wingless途径激活,其特征是存在一个保守的蛋白质基序,即高迁移率组(HMG)1盒,它介导DNA结合。TCF(T细胞因子)蛋白在发育过程中是必需的,包括对于淋巴细胞发育至关重要的TCF-1,以及参与神经元发育和LEF(白血病增强因子)的TCF-3和TCF-4。Wnt介导的信号通路诱导细胞质中的β-连环蛋白与细胞核内的TCF蛋白结合,从而增强Wnt靶向基因的表达。β-连环蛋白-TCF复合物受到腺瘤性结肠息肉(APC)肿瘤抑制蛋白的负调控,该蛋白使β-连环蛋白磷酸化,进而增加细胞质中β-连环蛋白的降解,从而抑制TCF蛋白的转录活性。APC基因的突变在结直肠癌中常见,会破坏这一调控途径,并与β-连环蛋白的积累和TCF靶向基因的激活增加相关联。

Could this antibody work for FA fixed chromatin immunoprecipitation?

Asked by: Anonymous
Thank you for your question. For use in ChIP we recommend using LEF-1 Anticorpo (B-6) X, as the gelatin in our standard solution could interfere with the experiment.

this antibody recognizes all LEF1 isoforms ? if it does, do you have any antibody against lef1 short isoforms (dominant negative isoforms) ? thanks !

Asked by: JoanaG
Thank you for your question. LEF-1 Antibody (B-6): sc-374522 has been raised against amino acids 61-130 mapping near the N-terminus of LEF-1 of human origin. It recognizes isoforms 1 (canonical), 2, 5, and 6. Since the amino acid sequences 1-115 are missing in isoforms 3 and 4, and 1-70 is missing in isoform 7, the antibody may not recognize these variants. LEF-1 Antibody (B-10): sc-374412 has been raised against amino acids 61-130 mapping near the N-terminus of LEF-1 of human origin as well. Please contact our technical service for further information or to arrange for a sample of the antibodies.

I am using LEF-1 (B-6): sc-374522 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: Dr Ninau Qelp
We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
