LSBio offers a selection of over 13,000 Expression-Ready ORF clones covering a variety of research species. Each clone is available in several mammalian and lentiviral expression vectors. Several of the expression vectors include protein tags fused to the clone in-frame. These ready-made clones can be used for overexpression of the gene of interest in vivo or for recombinant protein production and isolation in vitro. They offer the researcher significant savings of time and effort by allowing the researcher to commence experiments without having to first create and verify each expression construct.
