what is recombinant protein Recombinant protein is a manipulated form of protein encoded by recombinant DNA, which has been cloned in a foreign expression system to support the expression of the exogenous gene. This recombinant DNA construct can be used to manufacture large quantities of useful protein products. The recombinant DNA, usually the cDNA sequence of the target protein, is designed to be under the control of a well-characterized promoter to express the target protein within the chosen host cell to achieve high-level protein expression. https://www.creativebiomart.net/product/recombinant-proteins_1.htm
