对33例患者用0.0025%低浓度胰酶消化10分钟左右,行染色体 G 式显带,同时对12例患者用0.25%高浓度胰酶消化2～3分钟 G 式显带作对照,发现低浓度胰酶效果稳定、可靠、简单、易握掌。
Thirty-three patients were digested with 0.0025% trypsin at a low concentration for about 10 minutes, and chromosome G banding was performed. At the same time, 12 patients were digested with 0.25% high concentration of trypsin for 2 to 3 minutes. Pancreatin is stable, reliable, simple and easy to hold.
