以不同浓度的凝集素作为刺激剂，研究人外周血中的淋巴细胞的激活效应。结果白桂木凝集素促淋转浓度为１．２μｇ／ｍｌ，转化串７６％；红桂木凝集素和Ｊａｃａｌｉｎ的促淋转浓度为０．３μｇ／ｍｌ，转化率分别是６７％和８０％。在相同的条件下，对照ＰＨＡ的促淋转浓度是１６８μｇ／ｍｌ。几种凝集素的促转高峰均在７２ｈ出现。
Using different concentrations of lectins as stimulators, the activation effects of lymphocytes in human peripheral blood were studied. Results The concentration of leucocephalae promoting leaching was 1.2μg / ml and the transformation was 76%. The promoting concentration of leucogylin and Jacalin was 0.3μg / ml and the conversion rates were 67% and 80% respectively. Under the same conditions, the concentration of the control PHA was 168 μg / ml. Several lectins promote the peak appeared in 72h.
