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.通過研究，CDNF可防止6-羥基多巴胺（6-OHDA）誘導(dǎo)的多巴胺能神經(jīng)元變性，這可能對(duì)帕金森氏病有益。Recombinant Mouse CTACK/CCL27

IdeSProtease全稱免疫球蛋白G降解酶（ImmunoglubulinG-degradingenzymeofStreptococcuspyogenes,IdeS），是由人類致病菌釀膿鏈球菌（Streptococcuspyogenes）產(chǎn)生并分泌至胞外的一種半胱氨酸水解酶。該蛋白酶具有極高的底物特異性，能識(shí)別IgG，在抗體下鉸鏈區(qū)的特定位點(diǎn)進(jìn)行酶切，使IgG水解為完整的F(ab’)2片段和Fc片段。IdeS可識(shí)別人源和其他多種動(dòng)物來(lái)源的IgG，比如人、兔、猴、綿羊以及人動(dòng)物嵌合IgG等。IdeS具有獨(dú)特的底物選擇性，可以作為工具酶應(yīng)用于抗體類藥物或抗體融合蛋白藥物的結(jié)構(gòu)表征分析。本產(chǎn)品利用大腸桿菌重組表達(dá)，純度高，具有良好的酶切活性，是用于表征抗體、Fc融合蛋白和抗體-藥物復(fù)合物的有價(jià)值的工具。產(chǎn)品信息規(guī)格2000U/5000U產(chǎn)品性質(zhì)中文別名（Chinesesynonym）免疫球蛋白G降解酶英文別名（Englishsynonym）IdeSProtease來(lái)源（Source）大腸桿菌表達(dá)標(biāo)簽（label）N-terminalHisTag純度（Purity）經(jīng)SDS-PAGE及HPLC分析，純度>95%分子量（Molecularweight）35.3kDa緩沖液組分（Buffer）50mM磷酸鈉，150mMNaCl（pH6.6），50%glycerolBeta-Amyloid(1-14),mouse,rat（CDNF）也是一種新型神經(jīng)營(yíng)養(yǎng)因子，對(duì)多巴胺能神經(jīng)元的強(qiáng)大活性，與神經(jīng)膠質(zhì)細(xì)胞系衍生的（GDNF）相當(dāng)。
