I want to link two proteins with the linker (G4S)3. The linked (fused) proteins will then be expressed in E. coli. I will therefore be grateful if anybody could recommend a suitable DNA codon for this linker.
Just check the bacterial codon usage and select those with the most frequency in bacteria.
MICA and its receptor NKG2D were expressed as an inclusion bodies in E coli. It was therefore denatured and renatured employing dialysis method of refolding. Carrying out ELISA of MICA and it...

It has been documented that apoptotic cells themselves can induce phosphorylation of serine 139 on H2AX (γH2AX) due to DNA fragmentation during apoptosis (doi: 10.1074/jbc.275.13.9390). As γH2AX...
