核酸蛋白电泳图谱的拍摄技术

The photography of eletrophosis pattern of nucleic acid and protein

文章就电泳图谱的种类、胶片的选择、滤色镜的使用，怎样选择正确曝光时间以及相机镜头、光源设备的配置、使用做了介绍，并针对用考马亮兰染色的电泳图谱存在着反差较低的问题，叙述了从电泳图谱拍摄的开始到最后的冲洗胶片以及放大相片的全过程要始终围绕提高反差这一关键问题的方法。

This article introduces the types of pattern eletrophosis, the selection of films, the usage of colour filter, the choosing of appropriate exposure time, and the disposal of camera lens and illuminant equipment. As to the problem of lower contrast by using coomassie brilliant blue pattern eletrophosis, the author suggests methods of increasing contrast during the whole process of photography,from photographing development of films to enlarging of photographs.
