In vitro protein production (also known as cell-free protein expression or cell-free protein Synthesis) is a technique that enables researchers to rapidly express and create specific types of protein, particularly from living cells. Because commercial, large-scale protein manufacturing is not viable in vitro, it has a number of advantages that make it more adaptable and beneficial for a variety of applications. To begin, an in vitro production system enables researchers to control the levels of specific types of proteins required for the development, testing, and treatment of a disease or ailment.
Furthermore, cell-free protein expression enables the production of specific types of enzymes, the majority of which cannot be produced chemically. Sugars are broken down by a variety of enzymes. Probiotics (which assist to restore the balance of healthy bacteria in the digestive tract), immunoglobulin, and antimicrobial enzymes are all examples of enzymes that are commonly utilised in medicine and nutrition. Several experimental medicines based on enzyme therapies have been evaluated as successful treatments for various ailments and disorders in recent years. These experimental treatments have even proved successful in some circumstances.For instance, enzyme therapies have been developed to treat acquired brain damage caused by strokes and head injuries, age-related eye disease, and Parkinson's disease.
Furthermore, cell-free protein expression allows researchers to cultivate and harvest a wide range of live organisms, including fungi, viruses, and plants. The majority of living organisms get their food from their surroundings. Using cell-free protein expression, scientists have been able to culture and harvest several of these species. Some fungal cultures have even created medicine within living cells. For instance, in September 2021, a group of researchers from the UCL and MRC London Institute of Medical Sciences, U.K., revealed the results of their clinical trial concluding that lowering natural errors in protein expression can enhance lifespan and overall health in various organisms. This is the first instance of the production of medicine from living cells. Although this technology has not yet been extensively explored to its full potential, it represents a very important step forward in the development of medical care.
