Is it possible to insert a GFP gene in gDNA of U87MG by replacing some other gene at that place? If, yes then which GFP vector should I use to transfect in U87MG? Kindly tell me detail procedure to do this experiment ?
I have cloned a gene (750 bp) in pMAL-p5x expression vector. My protein is of size 29 kDa and it is fused with Maltose binding protein (42 kDa). I got 3 bands in SDS-PAGE after the protein...
