Abstract
Attachment enhanced human embryonic kidney cells, 293, are provided. These cells have been modified to contain a selected mammalian scavenger gene, which has been found to improve the ability of these cells to attach in culture. The improved cells of the invention are useful in assays in which the unmodified 293 cells could be used.
