N-糖苷酶F(PNGaseF)是一種酰胺水解酶,經(jīng)過(guò)和平空間站伊麗莎菌克隆,主要由腦膜炎膿桿菌等革蘭氏陰性菌分泌。酵母重組表達(dá)N-糖苷酶F(比活性:750000U/mL),可以裂解由天冬酰胺連接的高甘露糖、雜合和復(fù)雜的寡糖糖蛋白。PNGaseF的切割位點(diǎn)為糖蛋白內(nèi)側(cè)N-乙酰葡萄糖胺(GlcNAc)和天冬酰氨殘基之間的酰胺鍵,同時(shí)將酶解后蛋白上的天冬氨酰轉(zhuǎn)化為天冬氨酸。本產(chǎn)品帶his標(biāo)簽,常應(yīng)用于抗體及其相關(guān)蛋白完全去糖基化。另外,我司還提供其他類(lèi)型的糖苷酶,包括酵母重組表達(dá)的N-糖苷酶F,糖苷內(nèi)切酶H,糖苷內(nèi)切酶S。產(chǎn)品信息產(chǎn)品性質(zhì)中文別名(Chinesesynonym)N-糖酰胺酶F;N-糖苷酶F英文別名(Englishsynonym)PNGaseF來(lái)源(Source)酵母重組表達(dá)分子量(Molecularweight)36kDa比活性(Specificactivity)750000U/mL緩沖液組分(Buffer)20mMTris-HClpH7.5,50mMNaCl,5mMEDTA,50%Glycerolα-凝血酶的多面性質(zhì)在其臨床使用中提出了挑戰(zhàn),特別是在平衡其止血效果與血栓形成風(fēng)險(xiǎn)之間。Recombinant Mouse PSMP Protein,hFc Tag
產(chǎn)品簡(jiǎn)介凝血酶是由大小分別為31KD和6KD的兩條肽鏈通過(guò)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(cè)、血液或血漿的脫纖維化等;另外,由于凝血酶切割序列專(zhuān)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(jiàn)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 Canine ICAM-1/CD54 Protein,His Tag腸激酶能夠特異性識(shí)別并切割含有Aspartate-Aspartate-Aspartate-Lysine (DDDK) 序列的蛋白質(zhì)。
