[Detection of GLO I phenotypes in blood and blood stains using agarose starch gel electrophoretic analysis].
The distribution of GLO I phenotypes was studied using mixed agarose starch gel electrophoresis in 234 Chinese Han population in Changsha area. Three GLO I phenotypes were detected. The gene frequencies were as follows: GLO I1 = 0.1303 and GLO I2 = 0.8697. The phenotype frequencies of GLO I were compared not only among the different nationalities but with those reported by other countries. Both the 20 bloodstain samples kept at room temperature for 40 days and the other 20 bloodstain samples kept at 4 degrees C for at least 100 days could be correctly phenotyped. Two out of 8 watered bloodstains, their GLO I2-1 phenotype was changed to GLO I2-2. In blind trial, 15 bloodstain samples kept at room temperature for 40 days could be phenotyped correctly.
