Peripheral blood lymphocytes were cultured in microtiter plates with phytohemagglutinin which was added on the day of testing or had been previously pipetted and frozen. There was good correlation of transformation results using PHA concentrations from 0.25 to 10 microgram/ml (r = 0.772) to 0.828) PHA could be prepipetted and frozen for up to four weeks maintaining good correlation.
外周血淋巴细胞在微量滴定板中培养，加入的植物血凝素是在测试当天添加的，或者是预先吸取并冷冻的。使用浓度为0.25至10微克/毫升的植物血凝素时，转化结果具有良好的相关性（r = 0.772至0.828）。植物血凝素可以预先吸取并冷冻长达四周，仍能保持良好的相关性。
