Recombinant protein is a protein that it's code was carried by a recombinant DNA.The term recombinant DNA means that two segments of DNA in a plasmid. Plasmids are usually occurring in bacteria. When a recombinant DNA is inserted to a bacteria, this bacteria will produce protein based on this recombinant DNA. This protein iscalled recombinant protein.The use of bacteria in order to produce recombinant protein has grown in the recent years. Using recombinant DNA and inserting it to a plasmid of rapidly reproducing bacteria enables the manufacture of recombinant protein. These recombinant proteins can be variety of types, the can be Antibodies, antigens, hormones and enzymes
