With efficiencies near 100% and the ability to transduce virtually every cell type of interest, lentiviral vectors are the superstars of gene delivery. In the past, researchers made their own vectors or bought them off the shelf. Now, Baltimore, Md.-based Lentigen offers another option. Using the company's online LentiDesign tool - available at https://lentigen.com/products/custom/design - researchers can specify not only the gene or gene-silencing sequence, but also the promoter, reporter, envelope pseudotype and other elements of their desired vector.
