Biology: Separation Of Proteins

1150 words - 5 pages a basis from which a detailed study of proteins is possible. Following our procedure we were successfully able to set up a quantifying assay to determine the amount of protein within a milk sample, although our yield percentage was rather low. However, errors in this lab (in the form of a low yield percentage) may have an origin from our last lab. In the process of extracting proteins from the milk sample, we may have inadvertently lost some of the protein through erroneous measurements, or perhaps through poor handling of either ammonium sulfate or the dialysis tubing. While not sufficient enough (at this point) to invalidate our results, they do explain the major difference between the expected and the actual amount of protein extracted.
