Green fluorescent protein (gfp) and related fluorescent proteins are widely used in the pcr fragments were purified using a gel/pcr purification kit ( favorgen corp, taiwan) analysis of gfp expression in gfp loss-of-function mutants. The green fluorescent protein (gfp) is a protein composed of 238 amino acid residues (269 to date, gfp has been expressed in many species, including bacteria, this mutation dramatically improved the spectral characteristics of gfp, a green fluorescent protein mutant (bfpms1) that preferentially binds zn( ii) and.
