Thus, recombinant protein technology is required. Recombinant protein is a manipulated form of protein, which is generated in various ways to produce large quantities of proteins, modify gene sequences and manufacture useful commercial products A recombinant protein is a type of modified protein whose code is encoded by a recombinant DNA. Basically, a recombinant DNA is composed of two segments of DNA joined together in a plasmid (which are generally found in bacteria). When the recombinant DNA is inserted into the bacterial plasmid, they will translate these DNA into proteins. which bear the new sets of characteristics Recombinant Vaccines are revolutionary and have prevented viruses in millions of lives of people and animals.

Recombinant proteins, such as monoclonal antibodies, are produced in mammalian cell lines to introduce proper protein folding and post-translational modifications, which are essential for full biological activity. In both the industrial and academic environments, the use of recombinant proteins varies widely and, with it, the method of production Our fluorescent-labeled recombinant proteins are amine-labeled and rigorously tested to ensure consistent labeling of each lot. The proteins are manufactured with controlled procedures to ensure a consistent F/P ratio, and quality control tested by flow cytometry to evaluate equivalent staining As the bacteria multiply they manufacture molecules of human insulin. Once you have the product you need to extract and then purify. The products are recombinant proteins which can be injected in to the diabetic.Here recombinant DNA has its advantages because it keeps the production of insulin up and saves diabetics lives Recombinant protein vaccines are categorically safer than either killed whole pathogens or live attentuated pathogens, however they tend to need more doses to achieve protection and immunity wains with time and needs to be boosted.
