产品介绍:In mammalian cells, transcription is regulated in part by high molecular weight coactivating complexes that mediate signals between transcriptional activators and RNA polymerase (1). These complexes include CRSP (for cofactor required for Sp1 activation), which is required, in conjunction with TAFIIs, for transcriptional activation by Sp1 (2). CRSP is ubiquitously expressed in various tissues and functions as a multimeric complex that consists of nine distinct subunits (3). Several members of the CRSP family share sequence similarity with multiple components of the yeast transcriptional mediator proteins, including CRSP150, which is related to yeast Rgr1, and CRSP70, which is similar to the elongation factor TFIIS (4). CRSP77 and CRSP150 are also related to proteins within the putative murine mediator complex, while CRSP130 and CRSP34 are largely unrelated to either murine or yeast proteins (2,5). CRSP subunits also associate with larger multimeric coactivaor complexes, including ARC/DRI, which binds directly to SREBP and nuclear hormone receptors to facilitate transcription, and with NAT, a polymerase II-interacting complex that represses activated transcription (6,7).

Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.

6、纯化出抗体。

7、鉴定抗体。胎牛血清（无菌采制）

免疫荧光技术的实验步骤：

一、准备好试剂与仪器：

磷酸盐缓冲盐水、荧光标记的抗体溶液、缓冲甘油、搪瓷桶三只、有盖搪瓷盒一只、荧光显微镜、玻片架、滤纸、37℃温箱等。

二、实验步骤

1.滴加0.01mol/L，pH7.4的PBS于待检标本片上，十分钟后弃去，使标本保持一定湿度。

2.滴加适当稀释的荧光标记的抗体溶液，使其覆盖标本，置于有盖搪瓷盒内，保温一定时间以三十分钟为参考。

3.取出玻片，置玻片架上，先用0.01mol/L，pH7.4的PBS冲洗后，再按顺序过0.01mol/L，pH7.4的PBS三缸浸泡，每缸三到五分钟，并不停地摇晃振荡。

4.取出玻片，用滤纸吸去多余水分，但不使标本干燥，加一滴缓冲甘油，以盖玻片覆盖。

5.立即用荧光显微镜观察。观察标本的特异性荧光强度。

抗体的定义：

抗体（antibody），（免疫球蛋白不仅仅只是抗体）是一种由浆细胞（效应B细胞）分泌，被免疫系统用来鉴别与中和外来物质如细菌、病毒等的大型Y形蛋白质，仅被发现存在于脊椎动物的血液等体液中，及其B细胞的细胞膜表面。抗体能识别特定外来物的一个特征，该外来目标被称为抗原。

抗体的结构：

抗体是具有4条多肽链的对称结构，其中2条较长、相对分子量较大的相同的重链(H链)；2条较短、相对分子量较小的相同的轻链(L链)。链间由二硫键和非共价键联结形成一个由4条多肽链构成的单体分子。轻链有κ和λ两种，重链有μ、δ、γ、ε和α五种。 整个抗体分子可分为恒定区和可变区两部分。在给定的物种中，不同抗体分子的恒定区都具有相同的或几乎相同的氨基酸序列。可变区位于"Y"的两臂末端。在可变区内有一小部分氨基酸残基变化特别强烈，这些氨基酸的残基组成和排列顺序更易发生变异区域称高变区。高变区位于分子表面，最多由17个氨基酸残基构成，少则只有2 ～ 3个。高变区氨基酸序列决定了该抗体结合抗原抗原的特异性。一个抗体分子上的两个抗原结合部位是相同的，位于两臂末端称抗原结合片段(antigen-binding fragment, Fab)。"Y"的柄部称结晶片段(crystalline fragment,FC)，糖结合在FC 上。
