N-糖苷酶 F (PNGase F)酶活定義(UnitDefinition)1個酶活力單位指在10μL的反應體系中,37℃條件下1小時從10μg變性RNaseB中除去超過95%的碳水化合物所需要的酶量。儲存條件-15~-25℃保存,有效期1年。使用說明變性條件下蛋白質去糖基化1)在水中加入1μLBuffer1和目標糖蛋白(1-20μg),至終體積10μL;2)100℃溫度下煮沸10min使其變性,冰上冷卻,離心10秒;3)加入2μL的Buffer2、2μL的10%NP-40、6μL去離子水,總反應體積20μL;4)加入0.2~0.5μL的PNGase,輕輕混勻。在37℃孵育1-3h。非變性條件下蛋白質去糖基化1)在水中加入2μL的Buffer2和目標糖蛋白(1-20μg)至體積為20μL。2)加入0.5~1μL的PNGaseF,輕輕混勻。3)37°C孵育4-24h。注意:在變性條件下大多數底物能夠更好的去糖基化,在非變性條件下可能需要增加PNGaseF的量和延長孵育時間。eotaxin-2還具有抑制髓樣細胞增殖的能力,髓樣細胞增殖是Eotaxin不共有的生物學功能。
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.AFGF在調節細胞存活,細胞分裂,血管生成,細胞分化和細胞遷移中起重要作用。Recombinant Human Clusterin Protein,His Tag

產品簡介抑肽酶(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定復合物并阻斷酶的活性位點,這種結合是可逆的,大多數的抑肽酶-蛋白酶復合物在極端的pH<3.0的條件下解除結合。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。從結構上來說,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法規下生產,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,可替代動物源性抑肽酶用于各種生物技術過程中,如:重組蛋白生產中抑制絲氨酸蛋白酶的活性;細胞培養等。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合,推薦的結合pH>6.0,在pH<3.0的條件下不結合。可直接使用0.9%NaCl溶解,溶解后可-20℃儲存。Recombinant Mouse GPVI Protein,His Tag
