In 1977, human embryonic kidney cells were transformed with fragments of human adenovirus type 5, giving rise to today’s widely used HEK293 cell line. HEK293 has since become a popular choice for recombinant protein expression and viral production due to its relatively easy maintenance as well as its amenability to various transfection methods. In addition to basic research, recombinant HEK have greatly contributed to advances to biological manufacturing, pharmaceutical screening and development. Naturally, commercial kits and reagents for transfecting the HEK line are available, developed and optimized for your convenience and to suit your experimental needs.
