Lentivirus

Custom engineered Lentivirus vectors for gene overexpression and knockdown 

 Lentiviruses are the most versatile method for gene delivery. Lentiviruses infect the broadest panel of cells of dividing and non-dividing cells, including primary cells, immortalized cell lines, hematopoietic stem cells. Thanks to a large insert site for an expression cassette, lentivirus offers flexible vector design, including insertion of several genes with a total capacity up to 5 kb. Lentivirus become a tool of choice
whenever a fast, efficient and cost-effective generation of stable homogeneous cell models is required, either with a strong gene expression or when knockdown is needed. In gene therapy Lentivirus are widely used for CAR-T cell therapy applications.

 SIRION Biotech’s custom lentivirus service provides constitutive and inducible vectors for overexpression and gene knockdown. Our multicistronic vector design results in highly homogeneous, stable cell models avoiding time-consuming clonal selection posttransduction. With the all-in-one inducible vector system SIRION enables working with difficult, cytotoxic genes and shRNA strategies. We offer vectors in less than 4 weeks.
