Cell-free protein synthesis, also known as in vitro protein synthesis or CFPS, is the production of protein using biological machinery in a cell-free system, that is, without the use of living cells. The in vitro protein synthesis environment is not constrained by a cell wall or homeostasis conditions necessary to maintain cell viability. [ 1 ]
Cell-free production of proteins is performed in vitro using purified RNA polymerase, ribosomes, tRNA and ribonucleotides. These reagents may be produced by extraction from cells or from a cell-based expression system. Due to the low expression levels and high cost of cell-free systems, cell-based systems are more widely used. [29]

Cell-free protein array technology produces protein microarrays by performing in vitro synthesis of the target proteins from their DNA templates. This method of synthesizing protein microarrays overcomes the many obstacles and challenges faced by traditional methods of protein array production [1] that have prevented widespread adoption of protein microarrays in proteomics.
Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. Proteins perform a number of critical functions as enzymes, structural proteins or hormones.
In order to decipher this biological mystery, Nirenberg and Matthaei needed a cell-free system that would build amino acids into proteins. Following the work of Alfred Tissieres and after a few failed attempts, they created a stable system by rupturing E. coli bacteria cells and releasing the contents of the cytoplasm. [7]
Democratic Sen. Bob Casey is one of the longest-serving senators in Pennsylvania’s history. But his run of electoral success ended last month when he narrowly lost to Republican challenger Dave ...
Sutro's cell-free protein synthesis and site-specific conjugation platform, XpressCF+, contributed to the discovery of STRO-001 and STRO-002, internally-developed antibody drug conjugates, or ADCs. STRO-001 is an ADC targeting CD74, a protein highly expressed in multiple myeloma and non-Hodgkin's lymphoma , and is currently in a Phase I ...
