重組型TEV蛋白酶(rTEV)是經(jīng)過基因工程改造和純化后的重組蛋白酶,不僅保持天然TEV酶的功能活性,且在廣譜的溫度范圍內(nèi)表現(xiàn)出更強的穩(wěn)定性和特異性。rTEV是一種用來切除融合蛋白上親和標簽的常用工具酶,具有很強的位點特異性,嚴格識別七氨基酸序列EXXYXQ↓(G/S),切割位點在谷氨酰胺和甘氨酸/絲氨酸之間。普遍應(yīng)用的七氨基酸序列為:Glu-Asn-Leu-Tyr-Phe-Gln↓-Gly。rTEV在pH7.0,30℃時可達活性,但在pH6.0-8.5和溫度4-30℃范圍內(nèi)皆有活性(見表1),使得反應(yīng)條件的選擇可根據(jù)目的蛋白的情況而靈活變動。另外rTEV切割后也能利用其N端的6×His標簽,通過Ni-NTA樹脂去除,以達到純化目的蛋白的目的。產(chǎn)品性質(zhì)來源(Source)大腸桿菌外觀(Appearance)無色透明液體比活力(SpecificActivity)5U/μL活性定義(UnitDefinition)在1×rTEVBuffer(50mMTris,pH8.0,0.1mMEDTA,1mMDTT)中,30℃反應(yīng)1h,剪切>85%的3μg底物所需要的酶量定義為一個活性單位。純化(Purification)Ni柱親和純化純度(Purity)≥95%(bySDS-PAGE)產(chǎn)品組分運輸與保存方法冰袋運輸。CX3CL1受到促炎性刺激的上調(diào),包括巨噬細胞,樹突狀細胞,內(nèi)皮細胞,神經(jīng)元,平滑肌,上皮細胞的細胞類型。Recombinant Human HMGB1(His Tag)
