Protein ladders are a set of standards known as molecular weight proteins that are utilized to identify the approximate size of a protein molecule run on a PAGE gel electrophoresis. The challenges in running the ladders are the choice of appropriate protein standard as it is used as visual evidence of protein migration, transfer efficiency, and positive control. Suitable protein markers can be selected on the basis of required properties and applications, i.e., fluorescent ladder, IEF, 2D SDS-PAGE ladder, natural ladder with an isoelectric point, and optimized ladders for Western Blot chemiluminescence detection. The key factors for running a distinct protein ladder are buffer conditions, charge/voltage at migration time, and the gel's concentration.
I am currently using a recombinant protein which shows metal-dependent DNase activity. Is it possible to pinpoint the source of the DNase activity after protein purification? More specifically, can I ensure that the DNase activity is not because of nuclease contamination from the E.coli that might have persisted and passed with the protein of interest during purification?
