This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely as they can either by haemoglobin or cytochrome c‚ using the spectrometer their absorbance readings will determine if they are haemoglobin or cytochrome c.

oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase‚ the browner the substance will turn‚ and the faster it will achieve the color. In the present lab‚ different concentrations of catechol oxidase were mixed with pure catechol and the rate at which each solution browned was measured using a colorimeter. The results showed that the solution with the high concentration of catechol oxidase had the fastest rate at which it turned brown. However‚ it did not
