Insect cell lysate Cell-Free Protein Expression

Cell-free protein expression continuous exchange system based on insect cell extracts is a new in vitro cell-free expression system capable of synthesizing complex proteins such as membrane proteins.

Profacgen provides an insect lysate cell-free protein expression system with a membrane protein and glycosylation environment. The lysate contains some endogenous microsomal vesicles originating from the endoplasmic reticulum，which can be used as a place where the target protein is fused with a signal peptide and then modified.

Protocal of the insect lysate cell-free protein expression system:

1. Preparation of Spodoptera frugiperda (Sf21) cell extracts;
2. Add amino acid, T7 RNA polymerase, and energy substance to form the reaction system; or you can use our TNT system which is a single-tube, coupled transcription/translation system for the cell-free expression of proteins from DNA templates;
3. Add plasmid DNA or PCR products, synthesize mRNA in vitro under the action of RNA polymerase, incubate and detect; you can also use our companion vectors to improve translation efficiency; proteins are expressed from genes cloned downstream of the T7 promoter;
4. The mRNA released after translation is recycled using a cell-free system to synthesize the protein, and the mRNA is inactivated after repeated several times.

Advantages of the insect lysate cell-free protein expression system:

1. Easy cell breakage and quick preparation of extract
2. Various eukaryotic-specific modificationskede
3. Signal sequence processing
4. High-yield protein available for many downstream experiments
