Lymph node cells from guinea-pigs contact sensitive to 1-thiocyamo-2,4-dinitrobenzene have been fractionated by affinity chromatography over modified polyacrylamide beads. Cells mediating lymphokine release in response to active sensitizer were depleted only by chromatography over dinitrophyenyl (DNP) containing substrates and could be specifically eluted with DNP-glycine. DNP rosette-forming cells (RFC) were equally well depleted by chromatography using either DNP or trinitrophenyl containing materials but could not be eluted from the columns by DNP-glycine. While the antigen receptors of cells mediating the release of macrophage agglutination factor in response to DNP-containing antigens and of DNP-RFC were found to be hapten-specific, their specificity was shown to differ using chromatography over trinitrophenyl containing polyacrylamide.
对1-硫氰基-2,4-二硝基苯接触敏感的豚鼠淋巴结细胞,已通过在修饰的聚丙烯酰胺珠上进行亲和层析进行了分离。响应活性致敏剂介导淋巴因子释放的细胞仅通过在含二硝基苯(DNP)的底物上进行层析而被耗尽,并且可以用DNP-甘氨酸特异性洗脱。使用含DNP或三硝基苯基的材料进行层析时,DNP玫瑰花结形成细胞(RFC)同样能很好地被耗尽,但不能用DNP-甘氨酸从柱上洗脱下来。虽然发现响应含DNP抗原介导巨噬细胞凝集因子释放的细胞和DNP-RFC的抗原受体是半抗原特异性的,但使用含三硝基苯基的聚丙烯酰胺进行层析时,显示它们的特异性有所不同。
