產(chǎn)品介紹 Cancer-associated chromosomal changes often involveregions containing fragile sites. This gene maps to a commomfragile site on chromosome 7q31.2 designated FRA7G. This gene issimilar to mouse Testin, a testosterone-responsive gene encoding aSertoli cell secretory protein containing three LIM domains. LIMdomains are double zinc-finger motifs that mediate protein-proteininteractions between transcription factors, cytoskeletal proteinsand signaling proteins. This protein is a negative regulator ofcell growth and may act as a tumor suppressor. This scaffoldprotein may also play a role in cell adhesion, cell spreading andin the reorganization of the actin cytoskeleton. Multiple proteinisoforms are encoded by transcript variants of this gene.
Function : Scaffold protein that may play a role in cell adhesion,cell spreading and in the reorganization of the actin cytoskeleton.Plays a role in the regulation of cell proliferation. May act as atumor suppressor. Inhibits tumor cell growth.
Subunit : Interacts via LIM domain 1 with ZYX. Interacts (via LIMdomain 3) with ENAH and VASP. Interacts with talin, actin,alpha-actinin, GRIP1 and PXN. Interacts (via LIM domain 2) withACTL7A (via N-terminus). Heterodimer with ACTL7A; the heterodimerinteracts with ENAH to form a heterotrimer.
Subcellular Location : Cytoplasm. Cell junction, focal adhesion.Note=Detected along actin stress fibers.
Tissue Specificity : Ubiquitous.
Similarity : Belongs to the prickle / espinas / testin family.
Contains 3 LIM zinc-binding domains.
Contains 1 PET domain.

抗體的生物素化標(biāo)記實(shí)驗(yàn)要點(diǎn):
1. 抑制基因Testin抗體說(shuō)明書(shū) 如在反應(yīng)混合液中有疊氮鈉或游離氨基存在,會(huì)抑制標(biāo)記反應(yīng)。因此,蛋白質(zhì)在反應(yīng)前要對(duì) 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(huì)有所不同,選擇不當(dāng)則影響標(biāo)記的效率,應(yīng)先用幾個(gè)不同的分子比來(lái)篩選最適條件;
3.用NHSB量過(guò)量也是不利的,抗原的結(jié)合位點(diǎn)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(shí)可加入去污劑如 Triton x-100, Tween20等;
5.當(dāng)游離ε-氨基(賴(lài)氨酸殘基的氨基)存在于抗體的抗原結(jié)合位點(diǎn)時(shí),或位于酶的催化位點(diǎn)時(shí),生物素化會(huì)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(tuán),如羰基、氨基、巰基、異咪唑基及苯酚基,也可與糖基共價(jià)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(huì)對(duì)生物素化抗體與親和素的結(jié)合產(chǎn)生競(jìng)爭(zhēng)作用;
8.在細(xì)胞的熒光標(biāo)記實(shí)驗(yàn)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(duì)某些細(xì)胞可導(dǎo)致高本底。
抗體的鑒定:
1)抑制基因Testin抗體說(shuō)明書(shū) 抗體的效價(jià)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(jià)。不同的抗原制備的抗體,要求的效價(jià)不一。鑒定效價(jià)的方法很多,包括有試管凝集反應(yīng),瓊脂擴(kuò)散試驗(yàn),酶聯(lián)免疫吸附試驗(yàn)等。常用的抗原所制備的抗體一般都有約成的鑒定效價(jià)的方法,以資比較。如制備抗抗體的效價(jià),一般就采用瓊脂擴(kuò)散試驗(yàn)來(lái)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(shí)別能力??贵w的特異性高,它的識(shí)別能力就強(qiáng)。衡量特異性通常以交叉反應(yīng)率來(lái)表示。交叉反應(yīng)率可用競(jìng)爭(zhēng)抑制試驗(yàn)測(cè)定。以不同濃度抗原和近似抗原分別做競(jìng)爭(zhēng)抑制曲線,計(jì)算各自的結(jié)合率,求出各自在IC50時(shí)的濃度,并按公式計(jì)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(wú)窮大時(shí),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(diǎn)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(kù)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??贵w親和力的測(cè)定對(duì)抗體的篩選,確定抗體的用途,驗(yàn)證抗體的均一性等均有重要意義。
