Dear Skivesh,
My favourite media is TPB - (paper is: Moore et al Protein expression
and purification (1993) 4: 160-163). I've had luck with this and
BL21 (DE3) Gold cells. I'm also a fan of cold shocking cells - after
initial growth at 37 deg C, put flasks in an ice water bath for 10
min, then add IPTG and tranfer to 16-25 deg C for expression. This
combination rescued a protein that behaved like ball bearings in all
other conditions. It always seems worth trying an array of strains
vs an array of media vs cold shock/heat shock/chaperones, and a bit
of tweaking of [IPTG]
Good luck,
Lou
