Isolation, Cloning, Sequencing and Functional analysis of �-casein promoter along with the regions of exon1, intron1 and exon2 using mammary gland derived cell line of Buffalo (Bubulus bubalis)

摘要

The present invention relates to a method of in vitro isolation of buffalo beta-caesin promoter (buCSN2) along with the regions exon1, intron1 and exon2 from the genomic DNA in vitro (Bubalus bubalis) and its functional activity in using mammary cell line. The novel buffalo beta-caesin promoter along with exon1, intron1 and exon2 is isolated and cloned upstream of the Enhanced Green flourescence protein (EGFP) gene and sequenced. The transfection of the DNA construct resulted into production of EGFP protein in mammary cell lines, confirming bioactivity of this newly isolated buffalo promoter sequence. More specifically, the present invention relates to isolation, cloning, sequencing and functional analysis of the buffalo beta-casein promoter in vitro using mammary cell line.
