PubMedPubMed 产品介绍The classic group of Myelin basic protein (MBP) isoforms (isoforms 4 to 14) are with PLP the most abundant protein components of the myelin membrane in the CNS. They have a role in both its formation and stabilization. The smaller isoforms might have an important role in remyelination of denuded axons in multiple sclerosis. The non classic group of MBP isoforms (isoforms 1 to 3/Golli MBPs) may preferentially have a role in the early developing brain long before myelination, maybe as components of transcriptional complexes, and may also be involved in signaling pathways in T cells and neural cells. Differential splicing events combined to optional posttranslational modifications give a wide spectrum of isomers, each of them having maybe a specialized function. 靶点与功能
MBP(Myelin Basic Protein)是中枢神经系统少突胶质细胞合成的强碱性蛋白(pI 10.5-11),分子量14-21.5kDa(因剪切异构体差异),占髓鞘总蛋白的30%。其核心功能包括: 结构作用:通过与髓鞘脂质(如磷脂酰丝氨酸)结合,维持髓鞘多层膜结构的紧密性; 病理意义:MBP是多发性硬化(MS)的主要自身抗原,其抗体水平与疾病活动度正相关; 研究价值:用于检测脑白质损伤(如创伤性脑损伤、脑缺血)后的髓鞘降解,或评估脱髓鞘疾病模型的治疗效果。 实验操作关键要点
WB检测(脑组织裂解液): 样本处理:取大鼠脑白质组织,用含蛋白酶抑制剂的RIPA裂解液(1% Triton X-100)冰上裂解40分钟,15000g离心20分钟取上清; 电泳条件:15% SDS-PAGE凝胶(因MBP分子量小),恒压80V浓缩胶、120V分离胶,转膜使用0.22μm PVDF膜(200mA恒流45分钟); 抗体孵育:兔单抗1:2000稀释(5% BSA+TBST),4℃孵育过夜,HRP二抗(山羊抗兔)1:5000室温孵育1小时,曝光时间20-30秒。 IHC-P染色(脑切片): 抗原修复:采用柠檬酸钠缓冲液(pH6.0) 微波修复15分钟(95℃),避免高温导致MBP抗原丢失; 阳性定位:中枢神经系统白质区髓鞘呈棕黄色网状阳性,灰质区阴性(轴突无髓鞘); 对照设置:必须包含正常大鼠脑白质(强阳性)和MBP敲除小鼠脑切片(阴性对照)。 IF双标实验(与GFAP共染): 一抗组合:MBP抗体(兔源,1:200)+ GFAP抗体(小鼠源,1:500),4℃孵育过夜; 二抗选择:Alexa Fluor 594标记山羊抗兔(红)+ Alexa Fluor 488标记山羊抗小鼠(绿),室温避光孵育1小时; 结果判读:MBP标记髓鞘(红)与GFAP标记星形胶质细胞(绿)无共定位,边界清晰。 公司正在出售的产品
