小鼠白血病病毒(MuLV)分为两类: ①急性转化MuLV:Abelson,MuLV为其代表,基因组合有v-abl基因,编码产生p120gag-abl磷蛋白,诱发小鼠B淋巴细胞白血病; ②慢性转化MuLV:J大多数MuLV均属于此类。
zui近在人类中发现,异种鼠白血病病毒相关病毒(XMRV)与鼠白血病病毒密切相关(如Gag p30核心抗原有96%的一致性)。
早期的研究将XMRV与前列腺癌和慢性疲劳症联系起来;然而,新的发现对这些说法提出了异议,引发了科学家们新一轮的研究热潮~
艾美捷Cell Biolabs推荐众多MLV研究文章引用的,QuickTiter 小鼠白血病病毒(MuLV)核心抗原ELISA检测试剂盒
实验原理:将一种抗mulv p30单克隆包衣抗体吸附在微量滴定板上。样品或标准品中存在的mulv核心抗原(p30)与吸附在板上的抗体结合;添加抗mulv p30多克隆抗体并与抗体捕获的抗原结合。在孵育和洗涤步骤后,添加一种HRP结合的二级抗体并结合到抗mulv p30多克隆。在洗涤过程中去除未结合的HRP结合的二级抗体,并将与HRP反应的底物溶液加入到空中。有色产物的形成与样品中存在的mulv核心抗原的量成比例。通过添加酸终止反应,并在450 nm处测量吸光度。用重组mulv p30核心抗原制备标准曲线,测定样品浓度。
