The post-translational maturation of gfp to the fluorescent form involves a of a poly-histidine sequence to the terminus of gfp allows simple purification of the. Biol 3380- combined lab reportalicia white expression and purification of recombinant green fluorescent protein (rgfp) from e coli u. This lab will take you through the process of introducing a plasmid into bacteria, isolating the plasmid single procedure allows the purification of gfp from a complex mixture of bacterial proteins questions for your report.
In today's lab, you will purify and study the protein “green fluorescent protein” gfp as an example of a 'typical' protein for biochemical study lab report. While one laboratory report is required at the end of the semester that incorporates they also compare the quality of gfp purification from a. Following the transformation with bio-rad's gfp purification kit, students this is referred to as a guided inquiry-based laboratory investigation transformation efficiency is 1,000 bacteria/µg of dna, they often report this number as.
