  13. Then using ecbp21 antibody and immunogold transmission electron microscopy method, we studied the subcellular localization of ecbp21. the results indicated that the gold particles were mainly localized in the cell wall in callus cells and rachis cells of angelica dahurica. these results indicated that ecbp21 mainly localized in cell wall, which provide a direct evidence of the extracellular existence of ecbp21. furthermore, using ecbp21 antibody and immunohistochemical method, we studied the organic specially distribution of ecbp21, the results indicated that ecbp21 distributed in all organize, but it distributed more in leave n flower rachis than in leafstalk and root

    首先,構建了ecbp21表達載體,誘導了重組蛋白的表達,並通過膠回收法獲得了大量純化重組ecbp21蛋白,制備了高效價、高特異性抗體;隨后,利用ecbp21抗體,結合免疫膠體金電鏡定位技術進行了ecbp21亞細胞定位研究,結果顯示:在白芷愈傷組織細胞和花序軸細胞中金顆粒主要分佈在細胞壁區域,而在細胞內未發現或僅有少量金顆粒分佈,表明ecbp21蛋白主要定位於細胞壁區域,這為細胞外cambp ( ecbp21 )的胞外存在提供了直接證據:進一步,利用ecbp21抗體,通過免疫組織化學分析研究了ecbp21組織特異性分佈狀況,結果表明ecbp21在白芷各組織中均有分佈,但在葉、花、花序軸中分佈較多,而在葉柄、根中分佈較少。
