After doing the preliminary studies on redcrest protein extract, Tighnari proceeded with its characterization and analysis proper. He purified the crude protein extract through ammonium sulfate precipitation (40-60%) and gel filtration chromatography. Shown below are the results of the analyses. ||||| 250 kDa Crude Protein Extract 200 kDa 100 kDa 80 kDa 40 kDa 20 kDa ||| || Partially Purified Protein Extract Purified Protein Extract Figure D.1. Electrophoretogram obtained after NATIVE PAGE of the provided protein extracts. PAGE Analysis: 1. Based on Figure D.1., the series of purification procedures led to the isolation of two major redcrest proteins, COL and LEI. Determine the molecular weight of COL and LEI if the results of GFC showed that COL eluted out of the column first.
