產(chǎn)品介紹 The Notch signaling pathway controls cellular interactions important for the specification of a variety of fates in both invertebrates and vertebrates. Key players in the Notch pathway are the TLE genes (for transducin-like enhancer of split, also designated ESG for enhancer of split groucho), which are human homologs of the Drosophila groucho gene. Groucho is a transcriptional repressor that plays a key role in neurogenesis, segmentation and sex determination. TLEs associate with chromatin in live cells and specifically with Histone H3, but not with other core histones. Expression of the TLE genes, TLE1, TLE2, TLE3 and TLE4, correlate with immature epithelial cells that are progressing toward a terminally differentiated state, suggesting a role during epithelial differentiation. TLE1, TLE2 and TLE3 have elevated expression in cervical squamous metaplasias and carcinomas, while TLE4 is most highly expressed in the brain, particularly in the caudate nucleus. TLE1 and TLE4 contain SP and WD40 domains, through which TLE1 binds AML1 to inhibit AML1-induced transactivation of the CSF1 receptor. In early stages of cell differentiation, TLE1 is upregulated, and TLE2 and TLE4 are downregulated. In later stages, TLE2 and TLE4 are upregulated, and expression of TLE1 decreases.

Function : TLE4 (Transducin-like enhancer protein 4) is a member of the Groucho family of transcriptional corepressors and inhibits the transcriptional activation mediated by Pax5 and by beta-catenin and TCF family members in Wnt signaling.

Subunit : Homooligomer and heterooligomer with other family members. Binds PAX5, LEF1, TCF7, TCF7L1 and TCF7L2. Interacts with ZNF703; TLE4 may mediate ZNF703 transcriptional repression (By similarity).

Subcellular Location : Nuclear

Tissue Specificity : In all tissues examined, mostly in brain, and muscle.

Post-translational modifications : Phosphorylated. PAX5 binding increases phosphorylation (By similarity).

Ubiquitinated by XIAP/BIRC4.

Similarity : Belongs to the WD repeat Groucho/TLE family.

Contains 7 WD repeats.

抗體的生物素化標(biāo)記實驗要點：

1. B淋巴細胞基因1抗體費用 如在反應(yīng)混合液中有疊氮鈉或游離氨基存在,會抑制標(biāo)記反應(yīng)。因此,蛋白質(zhì)在反應(yīng)前要對 0.1mol/L碳酸氫鈉緩沖液或0.5mol/L硼酸緩沖液充分透析；

2.所用的NHSB及待生物素化蛋白質(zhì)之間的分子比按蛋白質(zhì)表面的ε-氨基的密度會有所不同,選擇不當(dāng)則影響標(biāo)記的效率,應(yīng)先用幾個不同的分子比來篩選最適條件；

3.用NHSB量過量也是不利的,抗原的結(jié)合位點可能因此被封閉,導(dǎo)致抗體失活；

4.由于抗體的氨基不易接近可能造成生物素化不足,此時可加入去污劑如 Triton x-100, Tween20等；

5.當(dāng)游離ε-氨基(賴氨酸殘基的氨基)存在于抗體的抗原結(jié)合位點時,或位于酶的催化位點時,生物素化會降低或損傷抗體蛋白的結(jié)合力或活性；

6.生物素還可能與不同的功能基團,如羰基、氨基、巰基、異咪唑基及苯酚基,也可與糖基共價結(jié)合；

7.交聯(lián)反應(yīng)后,應(yīng)充分透析,否則,殘余的生物素會對生物素化抗體與親和素的結(jié)合產(chǎn)生競爭作用；

8.在細胞的熒光標(biāo)記實驗中,中和親和素的本底低,但由于鏈霉親和素含有少量正電荷,故對某些細胞可導(dǎo)致高本底。

抗體的鑒定：

1）B淋巴細胞基因1抗體費用 抗體的效價鑒定：不管是用于診斷還是用于,制備抗體的目的都是要求較高效價。不同的抗原制備的抗體,要求的效價不一。鑒定效價的方法很多,包括有試管凝集反應(yīng),瓊脂擴散試驗,酶聯(lián)免疫吸附試驗等。常用的抗原所制備的抗體一般都有約成的鑒定效價的方法,以資比較。如制備抗抗體的效價,一般就采用瓊脂擴散試驗來鑒定。

2）抗體的特異性鑒定：抗體的特異性是指與相應(yīng)抗原或近似抗原物質(zhì)的識別能力?？贵w的特異性高,它的識別能力就強。衡量特異性通常以交叉反應(yīng)率來表示。交叉反應(yīng)率可用競爭抑制試驗測定。以不同濃度抗原和近似抗原分別做競爭抑制曲線,計算各自的結(jié)合率,求出各自在IC50時的濃度,并按公式計算交叉反應(yīng)率。 

如果所用抗原濃度IC50濃度為pg/管,而一些近似抗原物質(zhì)的IC50濃度幾乎是無窮大時,表示這一抗血清與其他抗原物質(zhì)的交叉反應(yīng)率近似為0,即該血清的特異性較好。

3）抗體親和力：是指抗體和抗原結(jié)合的牢固程度。親和力的高低是由抗原分子的大小,抗體分子的結(jié)合位點與抗原決定簇之間立體構(gòu)型的合適度決定的。有助于維持抗原抗體復(fù)合物穩(wěn)定的分子間力有氫鍵,疏水鍵,側(cè)鏈相反電荷基因的庫侖力,范德華力和空間斥力。親和力常以親和常數(shù)K表示,K的單位是L/mol。抗體親和力的測定對抗體的篩選,確定抗體的用途,驗證抗體的均一性等均有重要意義。
