News Center簡(jiǎn)介:K2單克隆抗體(mAb)
貨號(hào):10030005、10030010
規(guī)格:5ml、10ml
濃度:未稀釋的雜交瘤上清
形式:僅提供RPMI培養(yǎng)基,5%FCS培養(yǎng)基上清冰凍品
特異性: K2單克隆抗體識(shí)別雙鏈RNA的螺旋40或大于40bp的結(jié)構(gòu)。該抗體對(duì)雙鏈RNA的識(shí)別不依賴于抗原的序列或核苷酸組成。所有自然的雙鏈RNA結(jié)構(gòu),經(jīng)研究(40-50不同種)以及poly(I) .poly(C)和poly(A).poly(A).poly(U)均可被K1抗體識(shí)別(Schoenborn et al.)。盡管不同實(shí)驗(yàn)條件下,抗體對(duì)抗原的結(jié)合系數(shù)會(huì)有變化,但K1抗體的對(duì)poly(I).poly(C)的特異性高于其他雙鏈RNA抗原。K2抗體對(duì)所有的雙鏈RNA均有很高的親和力。
應(yīng)用: K2單抗用做夾心ELISA定量檢測(cè)雙鏈dsRNA,實(shí)驗(yàn)中抗體需用PBS需1:2稀釋。K2單抗也可用于免疫熒光檢測(cè)研究。(科研應(yīng)用)
穩(wěn)定性和保存:到貨后請(qǐng)分裝,并-70℃保存。加入10mM的疊氮鈉后,抗體可在4℃短期保存。長(zhǎng)期保存必需凍存,盡量避免反復(fù)凍融。
