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 ]
[6] [7] The cell extract-based type are susceptible to problems like quick degradation of components outside their host, as shown in a study by Kitaoka et al. where a cell-free translation system based on Escherichia coli (E. coli), of the cell extract-based type, had the mRNA template degrade very quickly and led to the halt of protein synthesis.
In the in situ method, protein synthesis is carried out on a protein array surface that is pre-coated with a protein-capturing reagent or antibody.Once the newly synthesized proteins are released from the ribosome, the tag sequence that is also synthesized at the N-or C-terminus of each nascent protein will be bound by the capture reagent or antibody, thus immobilizing the proteins to form an ...
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 ...
A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [ 1 ] [ 2 ] The solid phase is a water insoluble three dimensional network of polymers , having absorbed a large amount of water or biological fluids.
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]

Self-healing hydrogels are a specialized type of polymer hydrogel.A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.
