3C蛋白酶是切割小RNA病毒科非結(jié)構(gòu)蛋白的關鍵酶，在病毒復制過程中發(fā)揮著重要作用。鼻病毒屬于小RNA病毒科，其中的人鼻病毒3C蛋白酶基因編碼區(qū)全長552bp，編碼的蛋白質(zhì)相對分子質(zhì)量約為22000Da。人鼻病毒3C蛋白酶具有高度的酶切特異性，能特異切割位于Gln-Gly之間的肽鍵，識別位點為Leu-Glu-Val-Leu-Phe-Gln↓Gly-Pro。本公司將人鼻病毒3C蛋白酶的編碼區(qū)基因，在大腸桿菌中進行重組表達，純化后獲得了高純度的重組3C蛋白酶，該蛋白酶能特異切割含有3C酶切位點的融合蛋白，具有良好的生物學活性。同時，本公司生產(chǎn)的3C蛋白酶帶有GST和MAT標簽蛋白，有利于后期將其從酶切體系中去除。產(chǎn)品性質(zhì):中文別名（Chinesesynonym）:3C蛋白酶英文別名（Englishsynonym）:3CProtease來源（Source）:大腸桿菌表達標簽（label）:GST-3CProtease-MAT純度（Purity）:經(jīng)SDS-PAGE及HPLC分析，純度>95%分子量（Molecularweight）:47.38kDa比活性（Specificactivity）:500U/ml緩沖液組分（Buffer）:50mMTris-HCl，150mMNaCl，1mMEDTA，1mMDTT，pH7.0酶活定義（UnitDefinition）:在緩沖液中切割100μg被檢測的融合蛋白，反應條件為4℃16小時,切割率≥90%運輸和保存方法:干冰運輸；保存于-20℃。通過研究，CDNF可防止6-羥基多巴胺（6-OHDA）誘導的多巴胺能神經(jīng)元變性，這可能對帕金森氏病有益。

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。它在凝血過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，還負責提供反饋信號來尋找前輔因子：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）通過二硫鍵連接而成。某些情況下，α-凝血酶會發(fā)生自溶生成β-凝血酶和γ-凝血酶。β-凝血酶由對α-凝血酶A鏈水解并切割含有B鏈糖基化位點的小片段（B1，B2）組合而成。除了用于凝血研究之外，α-凝血酶還常用來位點特異性切割融合蛋白?；蛑亟M時將凝血酶識別位點插入在目的蛋白與利于后續(xù)純化和/或表達的多肽或者蛋白之間，通過凝血酶切割表達的重組子即可釋放目的蛋白。凝血酶本身可通過親和層析技術(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檢測確保凝血酶原的完全活化，并以NIH凝血酶的標準品為參考，提供的酶活力不少于3091NIHU/mg。Recombinant Rat IL-23R Protein,hFc Tag
