产品名称 DPP4/CD26 Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍The DPP4 gene encodes dipeptidyl peptidase 4, which is identical to adenosine deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic type II transmembrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. Dipeptidyl peptidase 4 is highly involved in glucose and insulin metabolism, as well as in immune regulation. This protein was shown to be a functional receptor for Middle East respiratory syndrome coronavirus (MERS-CoV), and protein modeling suggests that it may play a similar role with SARS-CoV-2, the virus responsible for COVID-19.

PubMedPubMed 靶点与功能 CD26(二肽基肽酶IV,DPP4)是一种跨膜丝氨酸蛋白酶,分子量约110kDa(同源二聚体形式),主要表达于活化T细胞、上皮细胞及内皮细胞表面。其核心功能包括: 酶活性作用:特异性切割肽链N端第2位脯氨酸残基,灭活GLP-1、GIP等肠促胰岛素,参与血糖调控(DPP4抑制剂是2型糖尿病治疗药物); 免疫调节:作为T细胞共刺激分子,通过与腺苷脱氨酶(ADA)结合增强T细胞活化,在关节炎、多发性硬化等自身免疫病中表达异常; 肿瘤微环境:在肺癌、结直肠癌中高表达,通过促进肿瘤细胞侵袭和血管生成参与疾病进展,是潜在的治疗靶点。 实验操作关键要点 WB检测(T细胞活化模型): 样本处理:Jurkat细胞经PHA(5μg/mL) 刺激48小时,RIPA裂解液(含1mM PMSF)冰上裂解30分钟,12000g离心15分钟取上清; 电泳条件:8% SDS-PAGE凝胶(因分子量较大),恒压80V浓缩胶、120V分离胶,转膜使用0.45μm PVDF膜(300mA恒流2小时); 抗体孵育:一抗1:2000稀释(5% BSA+TBST),4℃孵育过夜,HRP二抗(山羊抗兔/小鼠)1:5000室温孵育1小时,曝光时间60-90秒。 FCM分析(外周血T细胞): 抗体组合:PerCP标记CD26抗体(1μg/100μL细胞)与APC-CD3、PE-CD4抗体共染,4℃避光30分钟; 结果判断:正常人群CD4⁺T细胞中CD26⁺比例约60%-80%,活化后表达上调(可通过CD69共标验证)。 IHC-F(冷冻组织切片): 抗原修复:4%多聚甲醛固定15分钟后,0.1% Triton X-100透化10分钟,5%驴血清封闭30分钟; 阳性定位:小肠上皮细胞刷状缘、活化T细胞细胞膜呈绿色荧光(Alexa Fluor 488标记)。 公司正在出售的产品
