The ORF of profilin of Caryota mitis pollen was amplified by RT-PCR using specific primers and cloned into the expression vector pET-28a. The recombinant Caryota mitis pollen profilin was expressed in Escherichia coli BL21 (DE3). The recombinant protein was purified by affinity chromatography using Ni(superscript 2+) coupled sepharose.

然后设计带有酶切位点的特异性引物，采用RT-PCR获得整个短穗鱼尾葵花粉profilin的开放阅读框，将其与pET28a载体连接并转化大肠杆菌BL21(DE3)进行诱导表达，通过Ni(上标 2+)亲和层析柱对重组蛋白进行纯化，采用Western-blot检测其IgE结合活性。
