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.
N-糖苷酶F(PNGaseF)是一種酰胺水解酶,經(jīng)過和平空間站伊麗莎菌克隆,主要由腦膜炎膿桿菌等革蘭氏陰性菌分泌。酵母重組表達N-糖苷酶F(比活性:750000U/mL),可以裂解由天冬酰胺連接的高甘露糖、雜合和復雜的寡糖糖蛋白。PNGaseF的切割位點為糖蛋白內(nèi)側(cè)N-乙酰葡萄糖胺(GlcNAc)和天冬酰氨殘基之間的酰胺鍵,同時將酶解后蛋白上的天冬氨酰轉(zhuǎn)化為天冬氨酸。本產(chǎn)品帶his標簽,常應用于抗體及其相關(guān)蛋白完全去糖基化。另外,我司還提供其他類型的糖苷酶,包括酵母重組表達的N-糖苷酶F,糖苷內(nèi)切酶H,糖苷內(nèi)切酶S。產(chǎn)品信息產(chǎn)品性質(zhì)中文別名(Chinesesynonym)N-糖酰胺酶F;N-糖苷酶F英文別名(Englishsynonym)PNGaseF來源(Source)酵母重組表達分子量(Molecularweight)36kDa比活性(Specificactivity)750000U/mL緩沖液組分(Buffer)20mMTris-HClpH7.5,50mMNaCl,5mMEDTA,50%GlycerolKex2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。
產(chǎn)品簡介抑肽酶(Aprotinin),又稱為抑蛋白酶肽,是一種競爭性、可逆的絲氨酸蛋白酶抑制劑,可與絲氨酸蛋白酶形成穩(wěn)定復合物并阻斷酶的活性位點,這種結(jié)合是可逆的,大多數(shù)的抑肽酶-蛋白酶復合物在極端的pH<3.0的條件下解除結(jié)合。抑肽酶抑制糜蛋白酶、胰蛋白酶、激肽釋放酶和血纖維蛋白溶酶,不能抑制Xa因子和凝血酶。從結(jié)構(gòu)上來說,抑肽酶是一種來自牛肺的單體球狀蛋白,由58個氨基酸組成并排列在具有三個交聯(lián)二硫鍵的單個多肽鏈中。重組抑肽酶采用大腸桿菌表達,在GMP法規(guī)下生產(chǎn),不含任何動物源成分,無動物源性的病毒污染,氨基酸序列與來源于牛肺的抑肽酶完全一致,具有與動物源性抑肽酶相同的酶學性質(zhì),可替代動物源性抑肽酶用于各種生物技術(shù)過程中,如:重組蛋白生產(chǎn)中抑制絲氨酸蛋白酶的活性;細胞培養(yǎng)等。另外,也提供來源于牛肺的抑肽酶(動物源性)酶活單位:能抑制1個胰蛋白酶單位的活力稱為1個抑肽酶活力單位(EPU)。儲存條件凍干粉2~8℃保存,有效期2年。使用方法抑肽酶與蛋白酶是等摩爾有效結(jié)合,推薦的結(jié)合pH>6.0,在pH<3.0的條件下不結(jié)合??芍苯邮褂?.9%NaCl溶解,溶解后可-20℃儲存。AFGF在調(diào)節(jié)細胞存活,細胞分裂,血管生成,細胞分化和細胞遷移中起重要作用。Dermorphin
