產(chǎn)品介紹: 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).
抗體基本結(jié)構(gòu)：

抗體制備過程：

1.材料與試劑

 a．提取的動物 Ig

 b．弗氏佐劑和弗氏不佐劑

 d．實驗動物 兔

 e．其它材料及試劑

2、選擇實驗活體。

3、進行動物免疫實驗。

4、試取血樣進行測試，查看免疫效果。

5、如果免疫成功，殺死實驗活體，采集全部血清。

6、純化出抗體。

7、鑒定抗體。胎牛血清（無菌采制）

免疫熒光技術(shù)的實驗步驟：

一、準備好試劑與儀器：

磷酸鹽緩沖鹽水、熒光標記的抗體溶液、緩沖甘油、搪瓷桶三只、有蓋搪瓷盒一只、熒光顯微鏡、玻片架、濾紙、37℃溫箱等。

二、實驗步驟

1.滴加0.01mol/L，pH7.4的PBS于待檢標本片上，十分鐘后棄去，使標本保持一定濕度。

2.滴加適當稀釋的熒光標記的抗體溶液，使其覆蓋標本，置于有蓋搪瓷盒內(nèi)，保溫一定時間以三十分鐘為參考。

3.取出玻片，置玻片架上，先用0.01mol/L，pH7.4的PBS沖洗后，再按順序過0.01mol/L，pH7.4的PBS三缸浸泡，每缸三到五分鐘，并不停地搖晃振蕩。

4.取出玻片，用濾紙吸去多余水分，但不使標本干燥，加一滴緩沖甘油，以蓋玻片覆蓋。

5.立即用熒光顯微鏡觀察。觀察標本的特異性熒光強度。

抗體的定義：

抗體（antibody），（免疫球蛋白不僅僅只是抗體）是一種由漿細胞（效應B細胞）分泌，被免疫系統(tǒng)用來鑒別與中和外來物質(zhì)如細菌、病毒等的大型Y形蛋白質(zhì)，僅被發(fā)現(xiàn)存在于脊椎動物的血液等體液中，及其B細胞的細胞膜表面。抗體能識別特定外來物的一個特征，該外來目標被稱為抗原。

抗體的結(jié)構(gòu)：

抗體是具有4條多肽鏈的對稱結(jié)構(gòu)，其中2條較長、相對分子量較大的相同的重鏈(H鏈)；2條較短、相對分子量較小的相同的輕鏈(L鏈)。鏈間由二硫鍵和非共價鍵聯(lián)結(jié)形成一個由4條多肽鏈構(gòu)成的單體分子。輕鏈有κ和λ兩種，重鏈有μ、δ、γ、ε和α五種。 整個抗體分子可分為恒定區(qū)和可變區(qū)兩部分。在給定的物種中，不同抗體分子的恒定區(qū)都具有相同的或幾乎相同的氨基酸序列。可變區(qū)位于"Y"的兩臂末端。在可變區(qū)內(nèi)有一小部分氨基酸殘基變化特別強烈，這些氨基酸的殘基組成和排列順序更易發(fā)生變異區(qū)域稱高變區(qū)。高變區(qū)位于分子表面，最多由17個氨基酸殘基構(gòu)成，少則只有2 ～ 3個。高變區(qū)氨基酸序列決定了該抗體結(jié)合抗原抗原的特異性。一個抗體分子上的兩個抗原結(jié)合部位是相同的，位于兩臂末端稱抗原結(jié)合片段(antigen-binding fragment, Fab)。"Y"的柄部稱結(jié)晶片段(crystalline fragment,FC)，糖結(jié)合在FC 上。
