Cell culture in vitro,ABC ELISA,RNA dot blot and atom absorption spectrum analysis were used to study biological effects of low concentration of iron citrate (Fe cit) on the expression of transferrin receptor (TfR) in healthy human peripheral lymphocytes.

• 为了研究铁缺乏的生物学作用，采用体外细胞培养、ABC－ELISA法、RNA斑点杂交和原子吸收光谱分析等技术方法，观察了低浓度柠檬酸铁（Fe－cit）对健康人外周血淋巴细胞转铁蛋白受体（TfR）及其基因表达的影响。
