try codon optimisation use Rosetta 2 strains fuse to MBP I expressed a yeast protein of ~100 KDa, expression was low until I fused it to MBp (resulting protein ~ 150 KDa)

[ccp4bb] purification

Hello everyone, I am expressing a 100 KDa eukaryotic membrane protein in E coli. The protein is fused to 6His-MBP in the N terminus and the resulting mass is ~ 150 KDa. However, the protein get severely degraded so after putting through a Ni-NTA column, the protein came out with a lot of

Dear all, I am wondering if anyone is working on Blue Natve PAGE or other alternate methods. I need some help to troubleshoot my Native PAGE experiments. It will be great if anyone can help me in this regard. I am working on membrane proteins which have pI around less than 7. i need to run

[ccp4bb] LDAO SDS-PAGE

Hello everyone... I have a protein solubilised in 1% LDAO, 50 mM Phosphate pH 7.5, 150 mM NaCl. When I mix it with laemmli buffer and heat at 95C, 3 mins for SDS-PAGE, it aggregates (as in when you mix GuHCl with SDS) and can't be loaded onto the gel. Does anyone know why it happens? Thanks a
