Anti-CD94抗體,NK細(xì)胞表面抑制性受體CD94抗體產(chǎn)品介紹:Natural killer (NK) cells are a distinct lineage of lymphocytes that mediate cytotoxic activity and secrete cytokines upon immune stimulation. Several genes of the C-type lectin superfamily, including members of the NKG2 family, are expressed by NK cells and may be involved in the regulation of NK cell function. KLRD1 (CD94) is an antigen preferentially expressed on NK cells and is classified as a type II membrane protein because it has an external C terminus. Three transcript variants encoding two different isoforms have been found for this gene.
當(dāng)免疫組化染色沒有出現(xiàn)預(yù)期結(jié)果時(shí),應(yīng)系統(tǒng)地查找原因而每一次只能排除一種可能的原因。
對(duì)照/標(biāo)本無染色
① 確認(rèn)是否忽略了應(yīng)該加的某種試劑,包括一抗、二抗、三抗及底物等。
② 確認(rèn)所有的試劑是否按正確的順序加入,是否孵育了足夠的時(shí)間。
③ 對(duì)照抗體的標(biāo)簽確認(rèn)是否使用了正確的抗體,以及所用的檢測系統(tǒng)是否和一抗匹配,這一點(diǎn)是非常重要的。比如,如果一抗是兔來源的抗體,二抗一定要用抗兔的二抗來匹配;或一抗是小鼠的IgM一抗,二抗必須是山羊/兔抗小鼠的IgM(不是IgG)二抗。
④ 檢查抗體所使用的稀釋度及稀釋溶液。
⑤ 檢查抗體的有效期和保存條件,尤其是標(biāo)記了酶或熒光素的抗體,現(xiàn)在大多數(shù)試劑公司的抗體均要求在4~8℃條件下保存,應(yīng)避免反復(fù)凍融,試劑保存時(shí)一定要避免與揮發(fā)性有機(jī)溶劑同放一室,以免降低抗體的效價(jià)。
⑥ 檢查標(biāo)本的儲(chǔ)存條件,用已知陽性的標(biāo)本來同時(shí)做陽性對(duì)照。
⑦ 檢查色原/底物溶液,zui簡單的檢測方法是將一滴標(biāo)記有酶的抗體加入到制備好的底物溶液中,如果底物發(fā)生預(yù)期的顏色變化,則可排除底物的因素。需要注意的是,有些底物在制成工作液后應(yīng)在一定時(shí)間內(nèi)用完,否則會(huì)失效。
⑧ 檢查沖洗液是否和反應(yīng)試劑匹配,溶液的pH值很重要,與過氧化物酶底物匹配的溶液中不應(yīng)含有疊氮鈉。
⑨ 檢查復(fù)染劑和封片劑是否和所使用的色原匹配。
