用卧式平面二维电泳,并用敏感的银染色方法,首次比较了两个地区(无锡和郑州)中华按蚊的蛋白质多肽点的差异。全虫匀浆可查出142～144种蛋白质或多肽,两者之间有35点差异,其中2点为量的差异,33点为不同的多肽点。无锡的中华按蚊共有142个多肽点,差异点为16个,占11.3％;郑州的中华按蚊共有144个多肽点,差异点为19个,占13.2％。其总的差异点为12.2％。 Using horizontal plane two-dimensional electrophoresis and the sensitive silver staining method, we first compared the difference of protein polypeptide spots in Anopheles sinensis from two regions (Wuxi and Zhengzhou). There were 142 ~ 144 proteins or peptides in all the homogenates, with a difference of 35 points between them, of which 2 points were the difference in quantity and 33 points were different polypeptide points. Anopheles sinensis had a total of 142 polypeptide spots in Wuxi, with a difference of 16, accounting for 11.3%. There were 144 polypeptide spots in Anopheles sinensis in Zhengzhou, with a difference of 19, accounting for 13.2%. The total difference was 12.2%.
