SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that also include MERS?CoV and SARS-CoV-1. Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N). The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 .The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). Before binding to the ACE-2 receptor, structural analysis of the S1 trimer shows that only one of the three RBD domains is in the "up" conformation. This is an unstable and transient state that passes between trimeric subunits but is nevertheless an exposed state to be targeted for neutralizing antibody therapy. Polyclonal antibodies to the RBD of the SARS-CoV-2 protein have been shown to inhibit interaction with the ACE-2 receptor, confirming RBD as an attractive target for vaccinations or antiviral therapy.
糖苷內(nèi)切酶H是一種重組糖苷酶,能夠?qū)-糖蛋白中的高甘露糖和某些雜合型寡聚糖的殼二糖結(jié)構(gòu)進行切割,去除糖蛋白中的N-連接高甘露糖。糖苷內(nèi)切酶H克隆自褶皺鏈霉菌(Streptomycesplicatus)。并在酵母中重組表達。本產(chǎn)品帶his標簽,常應用于抗體及其相關蛋白完全去糖基化。另外,我司還提供其他類型的糖苷酶,包括糖苷內(nèi)切酶S(Cat#20413ES),酵母重組表達的N-糖苷酶F(比活性:750000U/mL),酵母重組表達的N-糖苷酶F(比活性:100000U/mL)。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(zhì)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Buffer2,8μL去離子水,總反應體積20μL;4)加入1-2μL的EndoH,輕輕混勻。在37℃孵育1-3h。5)65℃下熱失活10分鐘。非變性條件下蛋白質(zhì)去糖基化1)在水中加入2μL的Buffer2和目標糖蛋白(1-20μg)至終體積為20μL。2)加入2~5μL的EndoH,輕輕混勻。3)37°C孵育4-24h。注意:在變性條件下大多數(shù)底物能夠更好的去糖基化,在非變性條件下可能需要增加EndoH的量和延長孵育時間。lag-1是通過CCR5受體發(fā)出信號的CC趨化因子。 LAG-1與MIP-1β(ACT II同種型)相同,但兩個氨基酸取代。
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。鼠AFGF與人AFGF具有96%的氨基酸序列身份,因此它在鼠和人AFGF之間表現(xiàn)出相當大的物種交叉反應性。Recombinant Human IL-12B/p40/NKSF2 Protein,His Tag
