产品简介：

Drosophila S2 cells may be transfected with the recombinant expression vector alone to assay for transient expression of the protein of interest or in combination with pCoBlast to generate stable cell lines. We recommend that you test for expression of your recombinant protein by transient transfection before undertaking selection for stable cell lines. The method of choice for transfection of S2 cells is calcium phosphate. Stable cell lines expressing heterologous proteins can be generated in 2 weeks following cotransfection of the expression vector and the pCoBlast selection vector. By optimizing the ratio of expression vector to selection vector, cell lines with a very high copy number of the desired gene can be generated, leading to increased expression levels of the desired protein.
