| Abstract: | Objective To clone the promoter of buffalo β-casein gene. Method The buffalo DNA was extracted rom a hybrided-buffalo mammary gland.The promoter of buffalo β-casein gene was amplified by PCR which was cloned into the pGEM-T Easy vector. Results The sequencing analysis showed the promoter included CAAT and TTA signal ?progesterone regulatory region as well as octamer motif which was 100 percent of homologous to that of the milk cow. Conclusion Our results suggested. The DNA fragment is the buffalo β-casein upstream regulatory sequence. |
