Three pairs of primers were designed according to known DNA sequences tyrosinase in human and cattle, and exons 2, 3 and 4 were amplified of DNA sequences of tyrosinase in pig, which were 210, 135 and 182 bp in length.

• 实验根据人、牛的酪氨酸酶(TYR,tyrosinase)基因序列设计了3对引物,扩增出猪的酪氨酸酶基因外显子2,3,4序列,其长度分别为210,135,182bp。
