[器材與試劑]
1. 器材、電泳儀、電泳槽、醋酸纖維素薄膜
2. 試劑
(1) 浸泡醋酸纖維膜TBE緩沖夜(pH8.5);
(2) 電泳槽硼酸緩沖液(pH8.6;
(3)麗春紅染色液;
(4)漂洗液。
[步驟與方法]
1. 浸膜:將醋酸纖維素薄膜膜面向下放入浸膜液中,浸透后用眼科鑷子壓入液面底部。
2. 采血:碘伏消毒耳垂部,用一次性采血針采血,并將血液吸在兩次對折的濾紙尖部。
3. 加樣:將浸泡好的醋酸纖維素薄膜膜面向上放在濾紙上,用濾紙吸去多余的液體,在距一側(cè)1.5cm處用沾血的濾紙涂圓點狀(直徑約0.2cm)或線狀。
4. 電泳:將加好樣的醋酸纖維素薄膜膜面向下放入電泳槽中的緩沖液紗布上,加樣端放在負(fù)極,靜置2分鐘后開啟電源,調(diào)電壓200伏,電泳40分鐘。
5. 電泳結(jié)束后,關(guān)掉電源,觀察電泳圖譜,并記錄紅色區(qū)帶(幾條)及分布(位置)情況。
6. 染色: 將醋酸纖維素薄膜放入染色液中2分鐘,然后轉(zhuǎn)入漂洗液中洗至背底呈白色,再觀察結(jié)果。
電泳對比圖譜
含異常血紅蛋白的樣品:應(yīng)在未染色前觀察,除正常成分外,在任何位置出現(xiàn)的不經(jīng)染色的紅色區(qū)帶,均可記為有異常血紅蛋白存在。異常血紅蛋白常以HbA為標(biāo)準(zhǔn),分為快泳血紅蛋白和慢泳血紅蛋白。
[注意事項]
1. 醋酸纖維素膜一定要浸透(無白色斑點),加樣前從浸膜液中取出,既要吸去多余的液體還不能使膜太干,否則都會影響電泳結(jié)果。
2. 加樣時注意要加在醋酸纖維素的膜面,電泳時也要膜面向下放到電泳槽中的緩沖液紗布上。
發(fā)生細(xì)胞凋亡時,內(nèi)源性核酸酶被激活,染色體DNA鏈在核小體之間被切割,形成180~200個堿基或其整數(shù)倍的DNA的片段,將這些DNA的片段抽提出來進(jìn)行電泳,可得到DNA梯狀條帶(DNA ladder)。

[Equipment and Reagents]
1. Equipment, electrophoresis, electrophoresis tank, cellulose acetate film
Reagents
(1) soaking acetate film TBE buffer night (pH8.5);
(2) electrophoresis tank borate buffer (pH8.6;
(3) Ponceau dyeing liquid;
(4) rinse liquid.
[Steps and methods]
1. Dip film: The cellulose acetate film membrane surface down into the immersion liquid, soaked with ophthalmic forceps pressed into the liquid bottom.
2. Blood: iodophor disinfection of the earlobe, with a one-time blood collection needle blood, and the blood suction on the two fold the tip of the filter paper.
3. Sample loading: The soaked cellulose acetate membrane film on the filter paper on the up, with the filter paper to absorb excess liquid, 1.5cm away from the side of the filter paper with blood stained dots (diameter of about 0.2cm ) Or linear.
4. Electrophoresis: Add a good sample of cellulose acetate membrane surface down into the electrophoresis tank in the buffer gauze, sample end on the negative electrode, stand for 2 minutes after the power is turned on, the voltage 200 V, electrophoresis for 40 minutes .
5. After electrophoresis, turn off the power, observe the electrophoresis pattern, and record the red zone (a few) and distribution (position) situation.
6. Dyeing: The cellulose acetate film into the staining solution for 2 minutes, then transferred to the rinse to wash until the back is white, and then observe the results.
Electrophoresis contrast map
Samples containing abnormal hemoglobin: should be observed before staining, in addition to normal components, appear in any position without staining of the red zone, can be recorded as the presence of abnormal hemoglobin. Abnormal hemoglobin often HbA as the standard, divided into fast swimming hemoglobin and slow swimming hemoglobin.
[Precautions]
1. Cellulose acetate membrane must be soaked (no white spots), before adding the sample solution removed from the dip, it is necessary to absorb excess liquid can not make the membrane too dry, otherwise it will affect the electrophoresis results.
2. When adding sample attention to be added to the cellulose acetate membrane, electrophoresis membrane surface down to the electrophoresis tank buffer gauze.
In the event of apoptosis, the endogenous nuclease is activated and the chromosomal DNA strand is cleaved between nucleosomes to form DNA fragments of 180 to 200 bases or integer multiples thereof. The DNA fragments are extracted After electrophoresis, a DNA ladder can be obtained.
