What is Recombinant Proteins?

Recombinant proteins are a type of proteins that expresses in other species,  such as E.coli, yeast or mammalian system. And they have a lot of advantages.

As they have the known sequences,  researchers can change their amino acids and structures, that may improve their functions.
Because they are expressed in protein expression systems, proteins can be produced ona large scale. This is really good news for therapeutic applications where active protein is always needed.
