做血清蛋白醋酸纤维素薄膜电泳实验时,在电泳结束后,要将薄膜进行染色和漂洗,然后再将薄膜透明。薄膜放在透明液中适当时间后,取出平贴于玻璃板上,待膜干燥后,发现此膜不易从玻璃板上取下。因为在揭取的过程中.很容易使膜皱缩或把膜撕破。自来水的冲力容易使膜变形,而且往往使已经透明的薄膜变得模糊。经过多次反复的实践,发现只要将贴有膜的玻璃板置于电冰箱的冷藏室中2分钟左右,取出,用单面刀片将膜的一端挑起,即可很容易地将膜从玻璃板上揭下,揭下的膜不皱,不裂,非常平整光亮,适于长期保存或作定量扫描用。 Do serum protein cellulose acetate electrophoresis experiment, after electrophoresis, the film should be dyed and rinsed, and then the film is transparent. After the film is placed in the transparent liquid for an appropriate period of time, the film is taken out and put on the glass plate. After the film is dried, it is found that the film is not easily removed from the glass plate. Because in the process of extraction, it is easy to shrink the film or tear the film. The impact of tap water tends to deform the membrane and tends to blur the already transparent membrane. After repeated experiments, it was found that the film can be easily removed from the glass by simply placing the film-attached glass plate in a freezer for about 2 minutes in a freezer and pulling it out using a single-sided blade to raise one end of the film The plate is peeled off, uncovering the film is not wrinkled, not cracked, very smooth, suitable for long-term preservation or for quantitative scanning.
