Cell-free protein synthesis (CFPS) systems have been widely used for decades as a fast and effective tool in basic biology. Profacgen has developed a variety of protein expression systems using cell extracts, such as E. coli cell-free expression system, wheat germ cell-free expression system, rabbit reticulocyte lysate cell-free expression system, and tobacco cell-free expression system. Among them, Rabbit reticulocyte lysate, which reticulocytes are highly specialized cells primarily responsible for the synthesis of hemoglobin, is an efficient in vitro eukaryotic protein synthesis system used to translate foreign RNA (naturally or in vitro generated RNA).
The RNA used in the standard rabbit reticulocyte lysate translation system is derived from transcription products synthesized in vitro using SP6, T3, and T7 RNA polymerase promoters, requiring three separate reactions, and requiring multiple steps between each reaction.
Protocal of the rabbit reticulocyte lysate cell-free protein expression system:
Profacgen can now provide you with a TNT-coupled reticulocyte lysate system with shorter translation time and higher protein expression than traditional rabbit reticulocyte lysate translation systems. This is a single-tube, coupled transcription / translation system, which refers to the incorporation of transcription products directly into the translation mixture (including RNA polymerase, nucleotides, salts, RNasin nuclease inhibitors), only need to add templates (PCR fragments or plasmids) and methionine (generally radioisotope labels) to complete the entire translation process. At the same time we can provide different concentrations of Mg2+ and K+ and the option of adding DTT to optimize the translation process.
Advantages of the rabbit reticulocyte lysate cell-free protein expression system:
