Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.Kex2不能識別和切割單一堿性氨基酸即精氨酸或賴氨酸的羧基端肽鍵。Recombinant Human AITR Ligand/TNFSF18

Enterokinase,Recombinant,Expressed in E.coli大腸桿菌表達重組腸激酶(不帶標簽)注意事項1.本產品所講述的緩沖體系需要自行配置。2.不建議37℃條件下酶切,可能會有非特異性酶切出現(xiàn)。3.在>200mM咪唑,或>200mMNaCl,或>5%甘油,酶切會受到影響。如果樣品溶液中含有上述成分的一種或多種,為獲得理想的酶切結果,請先將樣品透析到25mMTris-HCl8.0緩沖液中,然后再進行酶切實驗;若不方便透析,可將樣品稀釋到咪唑含量在100mM以下,NaCl濃度在50mM以下,甘油濃度小于5%以下進行酶切,酶的用量與蛋白比例不變;若干擾因素很多,且不便去除,需要適當增加酶量或延長酶切時間,有助于得到理想的酶切效果。4.磷酸鹽對Enterokinase有很強的抑制作用,痕量的磷酸鹽都會嚴重影響Enterokinase的活性,因此在酶切體系內不能存在磷酸鹽。5.本品是具有高酶活力重組腸激酶,切割蛋白使用量少,可不考慮除去。后續(xù)如需去除重組腸激酶,可用陰離子交換樹脂(如DEAE-FF)對其進行洗脫。推薦洗脫條件如下:平衡緩沖液:25mMTris-HClpH8.0洗脫緩沖液:25mMTris-HClpH8.0,含100mMNaCl6.蛋白酶切效果不好,可適當增加酶量,或適當延長酶切時間。

產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,單體進一步聚合,在血小板、紅細胞和白細胞等參與下形成血凝塊,常用于診斷學中凝血化驗、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、生物化學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(包含凝血酶識別位點)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、生產穩(wěn)定性好等特點。該酶適切割位點: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),常見的識別序列為:1.Leu-Val-Pro-Arg-▼-Gly-Ser。2.Gly-Arg-▼-Gly。產品信息規(guī)格1KU/2KU猴痘病毒(Monkeypox Virus, MPXV)屬于正痘病毒屬。一般來說,同屬病毒具有相似的生物學特性。Recombinant Human IL-11
