产品介绍: FAT10, also designated Ubiquitin D or Diubiquitin, is a 165 amino acid protein encoded in the major histocompatibility complex (MHC) that consists of two domains which share significant homology with ubiquitin. Each domain contains two cysteines, along with a free C-terminal diglycine motif required for FAT10 conjugate formation. FAT10 is inducible by interferon-g and tumor necrosis factor a (TNF?). The FAT10 protein interacts with MAD2, a component of the spindle checkpoint, and plays a role in antigen presentation, cytokine response, apoptosis and mitosis. It may also regulate cell growth during dendritic cell or B cell activation and development. FAT10 mRNA is expressed mainly in some dendritic cells and lymphoblastoid lines and in other specific cells subsequent to interferon-g induction. The human FAT10 gene, designated UBD, maps to chromosome 6p21.3 and is overexpressed in the tumors of various epithelial cancers.

Ubiquitin-like protein modifier which can be covalently attached to target protein and subsequently leads to their degradation by the 26S proteasome, in a NUB1L-dependent manner. Probably functions as a survival factor. Conjugation ability activated by UBA6. Promotes the expression of the proteasome subunit beta type-9 (PSMB9/LMP2). Regulates TNF-alpha-induced and LPS-mediated activation of the central mediator of innate immunity NF-kappa-B by promoting TNF-alpha-mediated proteasomal degradation of ubiquitinated-I-kappa-B-alpha. Required for TNF-alpha-induced p65 nuclear translocation in renal tubular epithelial cells (RTECs). May be involved in dendritic cell (DC) maturation, the process by which immature dendritic cells differentiate into fully competent antigen-presenting cells that initiate T cell responses. Mediates mitotic non-disjunction and chromosome instability, in long-term in vitro culture and cancers, by abbreviating mitotic phase and impairing the kinetochore localization of MAD2L1 during the prometaphase stage of the cell cycle. May be involved in the formation of aggresomes when proteasome is saturated or impaired. Mediates apoptosis in a caspase-dependent manner, especially in renal epithelium and tubular cells during renal diseases such as polycystic kidney disease and Human immunodeficiency virus (HIV)-associated nephropathy (HIVAN).
抗体基本结构：

抗体制备过程：

1.材料与试剂

 a．提取的动物 Ig

 b．弗氏佐剂和弗氏不佐剂

 d．实验动物 兔

 e．其它材料及试剂

2、选择实验活体。

3、进行动物免疫实验。

4、试取血样进行测试，查看免疫效果。

5、如果免疫成功，杀死实验活体，采集全部血清。

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。

动物抗体功能分类：

①猪抗体：猪瘟抗体，猪蓝耳抗体，猪圆环病毒抗体，猪伪狂犬抗体，猪细小病毒抗体，猪口蹄疫抗体，猪流感抗体等。

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。
