GRO Alpha抗體做wb時(shí),一抗和二抗?jié)舛仁窃趺创_定的?怎么設(shè)置抗體滴度:
一抗的用量和樣品中的目標(biāo)分子含量相關(guān),如果含量較高,就不需要用太多一抗,以免浪費(fèi)和條帶太亮不易分析。推薦采用廠(chǎng)家的抗體濃度(義翹神州會(huì)提供抗體用量、天然細(xì)胞株檢測(cè)結(jié)果),如果樣品與廠(chǎng)家的不是一種細(xì)胞,可以嘗試上下摸索一兩個(gè)濃度梯度;
二抗的用量,和你所在實(shí)驗(yàn)室常規(guī)的用量就可以,如果出現(xiàn)效果不理想的狀態(tài),二抗的作用可以通過(guò)陽(yáng)性對(duì)照和陰性對(duì)照、以及其他人的使用效果看出來(lái)有沒(méi)有問(wèn)題。

GRO Alpha抗體ELISA如何選一抗與二抗:
一抗是與底物相結(jié)合的,同時(shí)一抗必須有抗原識(shí)別位點(diǎn),能被另一種抗體識(shí)別并結(jié)合。
二抗是能與一抗的抗原識(shí)別位點(diǎn)識(shí)別并結(jié)合,同時(shí),二抗必須有可以觀(guān)測(cè)、計(jì)量的性質(zhì)。
這些性質(zhì)可以是:
①二抗本身帶有顏色,可以通過(guò)分光度儀檢測(cè)到二抗的濃度;
②二抗還可以作為一種酶,催化另一種底物,通過(guò)檢測(cè)底物或者生成物的濃度檢測(cè)出二抗的濃度;等等……有很多,就是說(shuō)必須是可測(cè)量的。
GRO Alpha抗體保存得當(dāng)與否,直接決定了抗體的活性和使用效果!如果抗體保存得當(dāng),大部分抗體活性都可以維持?jǐn)?shù)月甚至數(shù)年。收到抗體后請(qǐng)務(wù)必在12000rpm離心20-30s后再打開(kāi)管蓋進(jìn)行分裝和保存!抗體使用非常特殊的儲(chǔ)存管,只有在12000rpm離心20-30s才能將附著在管壁或蓋內(nèi)的抗體全部離心下來(lái)。即使是在10000rpm離心也會(huì)導(dǎo)致離心不完全,導(dǎo)致出現(xiàn)抗體的量不足的現(xiàn)象!
