α-凝血酶(α-Thrombin)是一種高度特異性的絲氨酸蛋白酶,由凝血酶原(Prothrombin,II因子)經(jīng)蛋白水解活化而來(lái)。它在凝血過(guò)程中起著非常重要的作用,不僅能夠促使纖維蛋白凝塊的產(chǎn)生,還負(fù)責(zé)提供反饋信號(hào)來(lái)尋找前輔因子:V因子和VIII因子。也可以用作血管收縮劑。在體內(nèi),活化的X因子(FactorXa)切割凝血酶原,釋放出活性肽并將凝血酶切割成具有催化活性的α-凝血酶。α-凝血酶由一條輕鏈(Achain)(Mw~6,000)和一條重鏈(Bchain)(Mw~31,000)通過(guò)二硫鍵連接而成。某些情況下,α-凝血酶會(huì)發(fā)生自溶生成β-凝血酶和γ-凝血酶。β-凝血酶由對(duì)α-凝血酶A鏈水解并切割含有B鏈糖基化位點(diǎn)的小片段(B1,B2)組合而成。除了用于凝血研究之外,α-凝血酶還常用來(lái)位點(diǎn)特異性切割融合蛋白?;蛑亟M時(shí)將凝血酶識(shí)別位點(diǎn)插入在目的蛋白與利于后續(xù)純化和/或表達(dá)的多肽或者蛋白之間,通過(guò)凝血酶切割表達(dá)的重組子即可釋放目的蛋白。凝血酶本身可通過(guò)親和層析技術(shù)快速去除。本品是由勻質(zhì)化的人凝血酶原經(jīng)由Xa因子,Va因子和磷脂活化而得,經(jīng)SDS-PAGE檢測(cè)確保凝血酶原的完全活化,并以NIH凝血酶的標(biāo)準(zhǔn)品為參考,提供的酶活力不少于3091NIHU/mg。Recombinant Mouse AMIGO2 Protein,His Tag
