GFP, active recombinant protein

Jellyfish GFP, full length with C-terminal HIS tag, MW= 28.6 kDa, expressed in E-coli expression system. Absorbs light at 395 and 470nm, emits green fluorescence at 509nm. Useful as a quantitative control for GFP expression studies using GFP reporter vectors. It can also be used as a standard on protein gels and western immunoblots or for calibration of Fluorometers, flow cytometers and FACS machines.
