Hi all, I have two constructs having different ori, p15ori and M13 ori, different promoters araC and LacI, and different antibiotic resistance chloramphenicol and Ampicillin respectively. I would like to know which *expressing E. coli host cells* will be good for the co-transformation of these con

Hi All, I am purifying the biotinylated protein (cloned into the pET28a vector) using Avidin beads. Since I need the protein for SPR but when I used the purified protein to interact with Streptavidin coated onto the SPR chip. There was no signal. Can anybody tell me why is it so or how can I make

Hi, Is anyone has worked with STAT1 proteins? I have cloned the SH2 domain of STAT1 protein into pet28a vector but there was no expression so far or rather say inconsistent expression. Sometimes the expression was in inclusion bodies. I have tried different methods to pull out the protein from i
