Total RNA was isolated from cultured human pigmental cells and mRNA was reversly transcribed into cDNA. Then PCR was used to amplify the TRP -2 coding region. The PCR product was cloned into pUC19 plasmid and sequenced, then subcloned into vector pGEX-4T-1. The TRP-2 protein was expressed hi E coli of DH5 a as fusion protein with glutathioneS-transferase induced by IPTG. The fusion protein was purified by glutathione resin column.

我们通过RT—PCR的方法扩增TRP—2编码基因，克隆至pUC19载体并测序，再亚克隆至GST融合表达载体pGEX—4T—1，转化大肠杆菌，IPTG诱导表达了GST/TRP—2融合蛋白，并分析鉴定表达蛋白的可溶性，最后第四军医大学硕士学位论文一用谷氨酚胺树脂柱纯化表达的蛋白。
