Recombinant protein can be used in many different ways. The lab's purpose is to create functional proteins that have practical uses in fields such as medicine, food, agriculture, bioremediation, etc. This is accomplished by constructing a recombinant plasmid containing DNA sequence that corresponds to the target protein. The plasmid is then inserted into Pseudomonas fluorescens, which can then secrete the protein. The proteins manufactured in the lab have several uses. In the medical field, for example, proteins are biologically active in combination with specific receptors on the human cells and the complexes formed by them have vital roles in the processes of cell signaling, resulting in some biological responses or treatments.
