產(chǎn)品簡介凝血酶是由大小分別為31KD和6KD的兩條肽鏈通過二硫鍵組成的一種絲氨酸蛋白水解酶,可從動(dòng)物血漿中利用已凝血酶原水解制得,可催化纖維蛋白原(fibrinogen)水解釋放A肽和B肽,由此形成纖維蛋白單體,單體進(jìn)一步聚合,在血小板、紅細(xì)胞和白細(xì)胞等參與下形成血凝塊,常用于診斷學(xué)中凝血化驗(yàn)、凝血因子檢測、血液或血漿的脫纖維化等;另外,由于凝血酶切割序列專一,水解效率高,因此在分子生物學(xué)、生物化學(xué)或生物工程制藥研究中也常作為工具酶用于重組融合蛋白(包含凝血酶識(shí)別位點(diǎn))的特異性斷裂。本品是從牛的血漿純化制得,具有純度高、比活高、不含有其他蛋白酶活性、滅活病毒、生產(chǎn)穩(wěn)定性好等特點(diǎn)。該酶適切割位點(diǎn):A-B-Pro-Arg-▼-X-Y(其中,A和B為疏水氨基酸,X和Y為非酸性氨基酸),常見的識(shí)別序列為:1.Leu-Val-Pro-Arg-▼-Gly-Ser。2.Gly-Arg-▼-Gly。產(chǎn)品信息規(guī)格1KU/2KURecombinant Cynomolgus/Rhesus macaque CD47 Protein,His Tag鼠AFGF與人AFGF具有96%的氨基酸序列身份,因此它在鼠和人AFGF之間表現(xiàn)出相當(dāng)大的物種交叉反應(yīng)性。
