绿色荧光蛋白(GFP)是一种细胞内报告分子,广泛用于基因转移和表达的评估。增强变体已被克隆到适合许多不同细胞类型的各种表达载体中。为了研究感兴趣的基因对细胞周期进程的影响,需要结合DNA含量测量GFP表达。这种方法是困难的,因为大多数合适的荧光DNA染料太大而不能穿过完整的细胞膜,但渗透作用会使绿色荧光蛋白泄漏出来。作者提出了一种细胞制备技术的方案,旨在保持保持GFP荧光和获得足够的DNA直方图分辨率之间的微妙平衡。An描述了一种结合GFP荧光和细胞周期分析,使用重要染料Hoechst 33342染色的未渗透细胞。
Green fluorescent protein (GFP) is an intracellular reporter molecule widely utilized for assessment of gene transfer and expression. Enhanced variants have been cloned into various expression vectors suited for many different cell types. To study the effect of a gene of interest on cell cycle progression, it is desirable to measure GFP expression in combination with DNA content. This approach is difficult, as most suitable fluorescent DNA dyes are too large to pass through intact cell membranes, but permeabilization will allow GFP to leak out. The authors present a protocol with a cell preparation technique designed to maintain the delicate balance between retaining GFP fluorescence and obtaining adequate DNA histogram resolution. An describes a combined GFP fluorescence and cell cycle analysis using unpermeabilized cells stained with the vital dye Hoechst 33342.
