| [polymorphism of group specific component (gc) in nine han subpopulations in china]. | isoelectric focusing (ief) followed by immunofixation in thin layer polyacrylamide gels (ph4-6) was used to analyse the gc subtypes of 1841 individuals from nine han geographically distributed populations in china. the gc1f gene frequencies in these han subpopulations from lanzhou, huhhot, harbin, xi'an, zhengzhou, chengdu, guiyang, zhangzhou and harras in guangdong province were 0.3905, 0.4333, 0.4193, 0.4146, 0.4182, 0.4035, 0.4045, 0.4381 and 0.4347 respectively; gc1s were 0.3071, 0.2190, 0.2 ... | 1997 | 9575657 |
| polymorphism of phosphoglucomutase 1 (pgm1) in five han subpopulations in china. | pgm1 polymorphism in five han subpopulations in china was investigated by polyacrylamide gel isoelectric focusing. the frequency of pgm1*1a was 0.6256 for xi'an han, 0.5982 for zhengzhou han, 0.6429 for huhhot han, 0.6232 for lanzhou han, and 0.6000 for hakka in guangdong province. there was a north to south cline of pgm1*1a frequency. | 1995 | 8845334 |
