E3 ubiquitin-protein ligase that mediates ubiquitination of TFRC, CD86, FAS and MHC class II proteins, such as HLA-DR alpha and beta, and promotes their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. By constitutively ubiquitinating MHC class II proteins in immature dendritic cells, downregulates their cell surface localization thus sequestering them in the intracellular endosomal system.

Function:

E3 ubiquitin-protein ligase that mediates ubiquitination of TFRC, CD86, FAS and MHC class II proteins, such as HLA-DR alpha and beta, and promotes their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. By constitutively ubiquitinating MHC class II proteins in immature dendritic cells, down-regulates their cell surface localization thus sequestering them in the intracellular endosomal system.

1.特異性——免疫原

用于產(chǎn)生抗體的免疫原類型顯著影響抗體對靶蛋白的特異性。選擇針對不合適或質(zhì)量差的免疫原產(chǎn)生的抗體將導(dǎo)致不可靠且可能無法重現(xiàn)的結(jié)果。應(yīng)注意選擇針對已充分表征的免疫原產(chǎn)生的抗體。

2.肽

合成肽免疫原很少折疊成天然蛋白質(zhì)的類似三級結(jié)構(gòu)。此外，除非在合成過程中添加到肽中，否則它們不會表現(xiàn)出任何翻譯后修飾。因此，使用肽產(chǎn)生的抗體可用作蛋白質(zhì)印跡的有用試劑，因?yàn)橛捎跇悠诽幚磉^程中的變性和還原，靶蛋白具有線性化的表位。當(dāng)抗體需要區(qū)分具有高度保守氨基酸序列的兩種蛋白質(zhì)時，肽也可用作免疫原。在這些情況下，產(chǎn)生到差異區(qū)域的肽增加了制造差異抗體的可能性。

3.天然蛋白質(zhì)

如果將純化的蛋白質(zhì)用作免疫原，則針對它們產(chǎn)生的抗體可能無法識別蛋白質(zhì)印跡中變性蛋白質(zhì)的線性表位。一些使用天然蛋白質(zhì)產(chǎn)生的抗體只能識別蛋白質(zhì)表面的天然氧化構(gòu)象表位。對于單克隆抗體尤其如此。

1、制備抗原。

2、選擇實(shí)驗(yàn)動物。

3、動物免疫。

4、試取血進(jìn)行測試，看看是否成功免疫。

5、如果成功免疫，殺死實(shí)驗(yàn)動物，采集全部血清。

6、純化出抗體。

7、鑒定抗體。包括純度以及特異性。
一）抗原制備

Ig 是免疫球蛋白，對異種動物而言，是良好的抗原物質(zhì)。可以刺激異種動物產(chǎn)生抗 Ig 血清，

經(jīng)適當(dāng)提取后，產(chǎn)生抗 Ig 抗體，又叫第二抗體或抗抗體。在多數(shù)的間接標(biāo)記反應(yīng)中，均需制備

抗 Ig 抗體。
