人血清淀粉样蛋白P的分离,纯化及抗血清的制备   总被引:1,自引:1,他引:0  
目的分离、纯化人血清淀粉样蛋白P(SerumamyloidP,SAP);利用新西兰大白兔制备抗血清。方法新鲜人血清200ml与等体积4%琼脂糖凝胶(Sepharose-4B)混合,在钙离子存在条件下分离SAP,然后用二乙基氨基乙基琼脂糖凝胶CL—6B(DEAE—SepharoseCL-6B)离子交换层析技术进一步纯化SAP,用火箭电泳检测SAP组分,用十二烷基磺酸钠聚丙烯酰胺凝胶电泳(Sodiumdodecylsulfate-Polyacrylamidegelelectrophoresis,SDS-PAGE)检测其纯度,经A280(1%)=182测定其含量。用纯化的SAP与完全佐氏试剂混合注射于新西兰大白兔背部皮内,每次100μg,间隔10天,连续3次,第四次200μg,SAP总用量为500μg,10天后取血制备抗血清。结果从200ml人血清中提取纯品24mg,产率约40%。抗血清经双向扩散法测定效价为1:16。结论该改良法,操作简便,节省时间,但SAP产率并不低。  相似文献

采用20~200U/ml的重组人肿瘤坏死因子(rhTNF-α)处理体外液相培养的人早幼粒白血病细胞珠HL-60,观察到50~200U/ml的小剂量TNF具有诱导其向单核-巨噬细胞途径分化及抑制其增殖的效应。采用细胞总RNA打点杂交技术检测1~100U/mlTNF诱导HL-60细胞早期(12小时内)对其c-myc,c-fos原癌基因表达的影响,发现TNF可抑制c-mycmRNA水平及c-fos短暂性表达增高。结果表明此小剂量rhTNF-α具有诱导白血病细胞分化的效应及调控多癌基因表达的作用。  相似文献
