首先，构建了ecbp21表达载体，诱导了重组蛋白的表达，并通过胶回收法获得了大量纯化重组ecbp21蛋白，制备了高效价、高特异性抗体；随后，利用ecbp21抗体，结合免疫胶体金电镜定位技术进行了ecbp21亚细胞定位研究，结果显示：在白芷愈伤组织细胞和花序轴细胞中金颗粒主要分布在细胞壁区域，而在细胞内未发现或仅有少量金颗粒分布，表明ecbp21蛋白主要定位于细胞壁区域，这为细胞外cambp ( ecbp21 )的胞外存在提供了直接证据：进一步，利用ecbp21抗体，通过免疫组织化学分析研究了ecbp21组织特异性分布状况，结果表明ecbp21在白芷各组织中均有分布，但在叶、花、花序轴中分布较多，而在叶柄、根中分布较少。 - It is mainly characterized in the triangular - lanceolate leaves which are green but white with dark green reticulation along the midrib and more or less truncate at base ; the flowers are erect on the rachis and half - opened ; the lip is tripartite , glabrous , more or less urceolate in side view ; the hypochile is saccate , ovoid and big while the epichile is relatively tiny , reflexed , undivided and transversely oblong or subreniform
