IdeS Protease全稱免疫球蛋白G降解酶,酶活(Enzymeactivity)40U/μL酶活定義(UnitDefinition)在37℃條件下,反應(yīng)30min,剪切>95%的1μg重組單克隆IgG所需要的酶量定義為一個(gè)活性單位。儲(chǔ)存條件-25~-15℃保存,有效期1年。使用方法1.在消化液中加入適量IgG(加至5mg);2.在IgG樣本中加入IdeS蛋白酶(每1μgIgG加入1個(gè)單位的IdeS);3.將樣品置于37℃孵育30-60min。IdeS蛋白酶在中性pH或接近中性pH的緩沖中活性強(qiáng)。推薦反應(yīng)緩沖是50mM磷酸鈉,150mMNaCl(pH6.6),多數(shù)常見的生物緩沖也適用,比如Tris或PBS;注意:不在此pH范圍(例如乙酸鹽緩沖液)的緩沖也可能適用,但是孵育時(shí)間或酶量需要根據(jù)實(shí)際情況進(jìn)行優(yōu)化。注意事項(xiàng)1.IdeS不能識(shí)別切割小鼠IgG1/IgG2b,大鼠、豬、牛和山羊IgG,對小鼠IgG2a和IgG3具有中等酶切活性,酶切小鼠IgG2a和IgG3建議增加IdeS的用量(推薦用量為正常用量的5-10倍)。2.IdeS不能切割非IgG亞型的單抗分子,包括IgA、IgM、IgD和IgE。IdeS Protease全稱免疫球蛋白G降解酶是由人類致病菌釀膿鏈球菌產(chǎn)生并分泌至胞外的一種半胱氨酸水解酶。Recombinant Human APOE4/Apolipoprotein E Protein,HisTag

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.Recombinant Protein L (Freeze-Dried) 重組蛋白L(凍干)LAG-1與MIP-1β(ACT II同種型)相同,Lag-1趨化吸引力單核細(xì)胞,并表現(xiàn)出活性作為HIV抑制因子。
