注意事項(xiàng):
1.重復(fù)冷凍/融化循環(huán)可使抗體變性,導(dǎo)致其形成使抗體結(jié)合能力降低的聚集物。保存于-20℃對(duì)于大多數(shù)抗體是適當(dāng)?shù);保存?80℃無(wú)明顯優(yōu)勢(shì)。冰箱不能為無(wú)霜型。這些冷凍和融化之間的循環(huán)(以減少結(jié)霜)恰恰是應(yīng)該避免的。
2.抗體試劑瓶應(yīng)置于具有*小溫度波動(dòng)的冰箱區(qū)域,例如朝冰箱后部放置而不是置于門(mén)架上。有些研究人員加入冷凍保護(hù)劑甘油達(dá)到50%的終濃度以防止冷凍/融化損傷;甘油可將凝固點(diǎn)降低至低于-20℃。雖然這對(duì)于很多抗體是可接受的,但是只有一小部分我們提供的抗體測(cè)試了在該保存條件下的穩(wěn)定性,并且我們的保證僅使用于按數(shù)據(jù)表上的方式保存的抗體。不建議將包含甘油的溶液保存于-80℃,因?yàn)樵摐囟鹊陀诟视偷哪厅c(diǎn)。請(qǐng)注意甘油可被細(xì)菌污染,如果加入甘油或任何冷凍保護(hù)劑,則應(yīng)當(dāng)小心操作,以得到無(wú)菌制備物。
3.應(yīng)避免抗體在稀釋至工作濃度后在4℃下保存超過(guò)一天。蛋白質(zhì)在高濃度下保存時(shí)一般不易降解,理想的濃度為1mg/ml或更高。這是在抗體溶液中加入蛋白質(zhì)例如BSA作為穩(wěn)定劑的理論基礎(chǔ)。加入的蛋白質(zhì)也有助于減少抗體因結(jié)合于容器壁上而造成的損失。對(duì)于打算進(jìn)行偶聯(lián)的抗體而言,由于穩(wěn)定蛋白質(zhì)會(huì)與抗體競(jìng)爭(zhēng),降低了偶聯(lián)的效率,所以不應(yīng)加入穩(wěn)定蛋白質(zhì)。
溫馨提示:
在實(shí)驗(yàn)后,請(qǐng)注意回收稀釋的抗體;厥盏目贵w在進(jìn)行Western實(shí)驗(yàn)時(shí)至少可以重復(fù)使用10次。稀釋后的抗體,包括已經(jīng)使用過(guò)的稀釋抗體,4℃保存。回收后重復(fù)使用的抗體,使用方法同新鮮稀釋的抗體。如果在重復(fù)使用過(guò)程中發(fā)現(xiàn)抗體出現(xiàn)輕微混濁現(xiàn)象,可以10000g離心1-3分鐘,取上清用于后續(xù)檢測(cè)。如果回收的抗體出現(xiàn)明顯的絮狀物或長(zhǎng)霉長(zhǎng)菌等情況,則可以考慮廢棄該抗體。

 

 

 

選購(gòu)指南:rh-TNF-Alpha(rh-Tumor Necrosis Factor alpha) 重組人Control system in WB experiment of antibody products:
Blotting Western (immunoblotting), (Western) is also known as protein imprinting (blotting), which is based on the specificity of antigen antibody binding to detect the complex sample of a certain protein. This method is a new kind of immune technology based on gel electrophoresis and solid phase immunoassay. Because of the high specificity and sensitivity of SDS-PAGE, the high specificity and sensitivity of the determination of the high specificity and sensitivity of the determination of the high specificity and sensitivity, has now become a common technique for protein analysis. Western blot is used to identify a protein, and it can be used for qualitative and semi quantitative analysis.
WB control system: the positive control: the best standard, or positive serum, positive supernatant.
In the negative control, the serum was used to measure the serum of the mice, and the culture supernatant was measured with a non clonal culture supernatant. Blank control: no one anti 1%BSA instead. Unrelated control (alternative control): antibodies to an unrelated item, or unrelated to the project.
