ErbB-3抗体(G-4)是一种小鼠单克隆IgG2b kappa轻链抗体,针对人类ErbB-3 C端1315-1342氨基酸,ErbB-3是Erb-B受体酪氨酸激酶家族的重要成员。ErbB-3小鼠单克隆抗体(G-4)可识别该C末端区域内的表位,并表现出广泛的物种交叉反应性,可通过Western blotting(WB)、免疫沉淀(IP)、免疫荧光(IF)、流式细胞术(FCM)和酶联免疫吸附测定(ELISA)检测小鼠、大鼠、人、牛和猪样本中的ErbB-3。抗ErbB-3单克隆抗体(G-4)有非结合型和多种结合型,包括琼脂糖、辣根过氧化物酶(HRP)、藻红蛋白(PE)、异硫氰酸荧光素(FITC)和各种Alexa Fluor®结合物,可满足各种实验需求。ErbB-3,也称为FERLK、HER3、LCCS2、MDA-BF-1、VSCN1、erbB3-S和ERBB3,在控制生长、存活和分化的细胞通路中充当复杂的信号转导器。ErbB-3的信号传导机制包括与同族成员(尤其是Neu(ErbB-2/HER2))形成同源二聚体或异源二聚体,前提是ErbB-3的主要配体(即heregulin)已经结合。这种二聚化通过ErbB-3的C端区域特定YXXM基序的磷酸化,激活下游通路,特别是磷脂酰肌醇3激酶(PI3K)级联。ErbB-3在癌症生物学中的临床意义显而易见,ErbB-3在包括人类乳腺肿瘤在内的多种癌症中经常出现过度表达。这种失调会增强致癌信号和细胞存活机制,从而促进肿瘤进展并导致对治疗干预产生抗药性。ErbB-3 (G-4)抗体通过发挥这些不同的细胞作用,成为研究癌症发展机制和治疗抗药性途径的宝贵工具。

sc-7390 replaced product sc-285. Was the same epitope used for sc-7390 as used for the sc-285 antibody? I am trying to find information regarding epitope mapping for the discontinued sc-285 antibody (which mapped to 10 D3).

Is this erbb3 antibody should be applied as intercellular staining ? or as surface staining

Asked by: changl
Thank you for your question. ErbB-3 Antibody (G-4): sc-7390 is specific against amino acids 1315-1342. The C-terminal amino acid range between 665 – 1342 is cytoplasmic, so the antibody would recognize only the cytoplasmic part of its target protein.

How should the blocking peptide sc-7390 P be used?

Asked by: jenniferc
Thank you for your question. The blocking peptide is intended to be used as a negative control by preadsorbing the ErbB-3 (G-4): sc-7390 monoclonal antibody with it prior to application. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/peptide-neutralization

Rated 1 out of 5 by from Did not work for immunofluorescence (pig)Immunohistochemistry: the antibody was tested on mammary parenchyma and uterus from 6 months old female pigs. Antigen retrieval was performed in citrate buffer, 30'. Primary antibody: 1:50 dilution, 1h, RT. Secondary antibody: Alexa Fluor 488 (1:500), 1h, RT. Results: negative; nonspecific signal was observed both in epithelial and connective fractions. Immunocytochemistry: the antibody was tested on porcine mammary epithelial cells isolated from 6 months old gilts. Cells were fixed with acetone-methanol (1:1) and stained as above (see immunohistochemistry). Primary antibody was diluted 1:100. Result: negative.
