普洱茶茶褐素單克隆抗體的制備
[Abstract]:Pu'er tea is a unique kind of tea in Yunnan and other regions of China. During the processing of Pu'er tea, the content of tea brownin has been increasing, and it is also the most abundant pigment in polyphenol oxidation products. And the quality of Puer tea has a very important role. The main results of this study were as follows: spleen cells were obtained from mice immunized with thefuscin as antigen and fused with myeloma cells (SP2/0) from the same strain of mice. Positive hybridoma cells were cloned and screened. Then the positive hybridoma cells were injected into the abdominal cavity of mice to prepare monoclonal antibodies. Ascites were purified by G protein affinity chromatography. Westernblot analysis showed that the obtained antibody was a monoclonal antibody to tea brownin, and the type and subtype of 2E4 hybridoma were determined by ELISA method. The preparation of monoclonal antibody against brownin in Puer tea provides a theoretical basis for the establishment of a method for determining the quality of puer tea.
