產(chǎn)品介紹 This gene belongs to the TIMP gene family. The proteins encoded by this gene family are natural inhibitors of the matrix metalloproteinases (MMPs), a group of peptidases involved in degradation of the extracellular matrix. In addition to its inhibitory role against most of the known MMPs, the encoded protein is able to promote cell proliferation in a wide range of cell types, and may also have an anti-apoptotic function. Transcription of this gene is highly inducible in response to many cytokines and hormones. In addition, the expression from some but not all inactive X chromosomes suggests that this gene inactivation is polymorphic in human females. This gene is located within intron 6 of the synapsin I gene and is transcribed in the opposite direction. [provided by RefSeq].
Function : Complexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. Also mediates erythropoiesis in vitro; but, unlike IL-3, it is species-specific, stimulating the growth and differentiation of only human and murine erythroid progenitors. Known to act on MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-11, MMP-12, MMP-13 and MMP-16. Does not act on MMP-14.
Subcellular Location : Secreted.
Post-translational modifications : The activity of TIMP1 is dependent on the presence of disulfide bonds.
Similarity : Belongs to the protease inhibitor I35 (TIMP) family.
Contains 1 NTR domain.
合成與降解(Synthesis and Degradation)
TIMP1是基質(zhì)金屬蛋白酶的抑制酶,其功能與MMP相反,能細(xì)胞的浸潤和轉(zhuǎn)移,主要用于各種如等的研究。TIMP-1是一種28kDa的糖蛋白,主要分泌細(xì)胞為多種結(jié)締組織細(xì)胞,被認(rèn)為是組織中MMPs活性的主要調(diào)節(jié)者,它可以和MMPs家族成員以共價鍵方式形成1:1的復(fù)合物,從而發(fā)揮其。在正常生理條件下,MMPs和TIMPs之間的平衡狀態(tài)是維持細(xì)胞外基質(zhì)正常狀態(tài)所必需的,一旦它們之間的比例失調(diào),就會造成一系列的病理狀態(tài)。

抗體的生物素化標(biāo)記實驗要點:
1. 金屬蛋白酶組織抑制因子-1抗體(N端)品牌 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(tuán),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(xì)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(xì)胞可導(dǎo)致高本底。
抗體的鑒定:
1)金屬蛋白酶組織抑制因子-1抗體(N端)品牌 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(kuò)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(kuò)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。抗體的特異性高,它的識別能力就強(qiáng)。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。
