After removing DNA, histones and part of NHPs, we found that actin and tropomyosin exist in the polytene chromosomal scafiold by immunofluorescence experiments.

对去除DNA、组蛋白和大部分非组蛋白的果蝇多线染色体的免疫荧光实验表明，肌动蛋白和原肌球蛋白存在于果蝇多线染色体骨架上。

Methods Mature larvae of blackflies were selected, dissected and shelled out salivary glands. The traditional method was improved, and the clear polytene chromosomes slices were prepared after the use of new staining fluid, flush fluid and cleaning fluid.

选用经Carnoy's液固定的蚋成熟幼虫进行解剖、剥离唾腺，对传统蚋类唾腺多线染色体制备方法进行改进，包括改良染色液，使用冲洗液、背景净化液等新制剂和新步骤并得到清晰的蚋唾腺染色体图形。

The purpose of this laboratory is to train undergraduate students with practical genetics, including the basic principles of genetics, inheritance of pea traits, root tip chromosomes, Drosophila salivary polytene chromosomes, meiosis, statistical methods, bacterial antibiotic resistance, plasmid isolation, restriction, and gel electrophoresis, blood type, and human genetics.
