C-banding techniques detect the presence of constitutive heterochromatin, which is usually located in centromeric regions of chromosomes in the majority of analysed species. The common method for C-banding used over the last 30 years involves treatment with a mild alkali barium hydroxide 5% Ba(OH)2 at 50 degrees C for 5-15 min and subsequent incubation in salt solution (2 x SSC at 60 degrees C for 1 h). We here present a new, easy and reliable technique for C-banding, which basically involves heat denaturation of chromosomal DNA in the presence of formamide and incubation in 2 x SSC at room temperature.
