ABSTRACT
<p><b>OBJECTIVE</b>To study the allergen in key processes during the production of Fufang Kushen injection by IgG promoter-HepG2 cells in vitro.</p><p><b>METHOD</b>By transfecting a IgG promoter-regulating the expression of green fluorescent protein(GFP) plasmid into HepG2 cells, this transferred cells were incubated with common allergens (like puerarin, ovalbumin, LPS or Sal typhoid vi polysaccharide vaccine), excipients using in Fufang Kushen injection (NaOH, acetic acid, Tween-80 and ethanol) and samples from the key production processes of the injection for 30 minutes . Fluorescent photographs were analyzed the fluorescence intensity of the cells by using an image analysis software.</p><p><b>RESULT</b>All of common allergens significantly increased the IgG expression. Two of the excipicents, acetic acids and Tween-80 were shown to increased the IgG expression, while others had no effect on IgG expression. In the 8 samples from the key processes in the production of Fufang Kushen injection, two of them stimulated IgG expression.</p><p><b>CONCLUSION</b>IgG promoter-HepG2 cells are highly sensitive and specific to allergens, and thus can be applied to rapid screening of allergens in components and injections in transcriptional level. It is possible to use the IgG-promoter HepG2 cells in a real-time monitoring of allergens in the production processes of Chinese medicine injections.</p>
