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30min,剪切>95%的1μg重組單克隆IgG所需要的酶量定義為一個活性單位。儲存條件-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。推薦反應緩沖是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,但是孵育時間或酶量需要根據實際情況進行優(yōu)化。注意事項1.IdeS不能識別切割小鼠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趨化吸引力單核細胞,并表現(xiàn)出活性作為HIV抑制因子。
