产品介绍 This gene encodes a member of the ATP-binding cassette (ABC) transporter superfamily. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily that is involved in multi-drug resistance. The encoded protein functions as a chloride channel and controls the regulation of other transport pathways. Mutations in this gene are associated with the autosomal recessive disorders cystic fibrosis and congenital bilateral aplasia of the vas deferens. Alternatively spliced transcript variants have been described, many of which result from mutations in this gene. [provided by RefSeq, Jul 2008]
CFTR是一种独特的氯离子通道,尽管称为氯离子通道,但在结构上却明显地不同于其他氯离子通道,属于一种ATP结合盒转运体(ATP-binding cassettetransporter, ABC)家族。CFTR主要为氯离子跨上皮运动提供了选择性通道,对于跨上皮的盐类运输、液体流动和离子浓度调节等都具有重要的决定作用。
CFTR分布广泛,许多器官,如肺、肝、胰腺、肠、生殖腺等的细胞膜中都有表达,尽管称为氯离子通道,但还涉及到其他一价阴离子的运输,由于生理条件下氯离子最为重要,故称为氯离子通道,近年来,它一直是离子通道研究中的一个热点。
抗原抗体结合特点
1)特异性:抗原分子只能与由它刺激所产生的抗体结合而起反应的专一性能;
2)可逆性:是指Ag与相应Ab结合成IC后,在一定条件下可解离为游离抗原与抗体。
3)阶段性:
一阶段:特异性结合阶段 (①反应速度快,几秒钟或几分钟即可完成 ②不出现肉眼可见反应);
第二阶段:可见阶段(表现为凝集、沉淀、补体结合等反应 ①反应进行慢,需要几分钟、几十分钟或更长②受电解质、温度、酸碱度等多种因素影响)。
4)比例性:(最适比或等价点)是指抗原与抗体发生可见反应需遵循一定的量比关系,只有当二者浓度比例适当时,才出现可见反应。
抗原抗体反应影响因素:
(一)反应物自身的因素
5) 抗体:不同来源的抗体,反应性各有差异,抗体的浓度、特异性和亲和力都影响抗体抗原反应,为提高试验的可靠性,应选择高特异性、高亲和力的抗体作诊断试剂.等价带的宽窄也影响抗原抗体复合物的形成,单克隆抗体不适用于沉淀反应.
6) 抗原:抗原的理化性状、分子量、抗原决定簇的种类及数目均可影响反应结果.颗粒性抗原出现凝集反应,可溶性抗原出现沉淀反应,单价抗原与相应抗体结合不出现沉淀现象.
(二)反应环境条件
7) 酸碱度:抗原抗体反应必须在合适的pH环境中进行.蛋白质具有两性电离性质,因此每种蛋白质都有固定的等电点.抗原抗体反应一般在pH6~9进行,有补体参与的反应pH为7.7.4,pH过高或过低都将影响抗原与抗体反应.
8) 温度:在一定范围内,温度升高可加速分子运动,抗原与抗体碰撞机会增多,使反应加速.一般为15℃~40℃,常用的抗原抗体反应温度为37℃,温度如高于56℃,可导致已结合的抗原抗体再解离,甚至变性或破坏.每种试验都有其独特的最适反应温度要求.此外,适当振荡也可促进抗原抗体分子的接触,加速反应.
9) 电解质:抗原与抗体发生特异性结合后,虽由亲水胶体变为疏水胶体,若溶液中无电解质参加,仍不出现可见反应.为了促成沉淀物或凝集物的形成,常用0.85%NaCl或各种缓冲液作为抗原及抗体的稀释液.
