The goal of this lab was to create and purify DHFR from BL21 ecoli using column chromatography. To know if we isolate DHFR their will be one band at 53 KD or above 50 KD and in our desalted eluate page should have the highestOD₂₈₀ which translates to the highest enzyme activity .Column chromatography is a method used to purify individual chemical compounds from mixtures of compounds. The main advantage of column chromatography is the relatively low-cost and disposability of the stationary phase used
