Protein Overexpression and Purification from Bacteria

This illustration describes the key steps for protein overexpression and purification from bacteria. First, the desired gene is introduced into bacterial cells through transformation. Upon selection for transformed cells, protein production is induced. Cells are then lysed to release the overexpressed protein. Protein purification analysis follows, typically utilizing western blot. Post-purification analysis confirms protein identity and assesses purity. Dialysis removes residual contaminants, and finally, an activity assay validates protein functionality. This technique is crucial for obtaining pure proteins for downstream applications.
