Gene Tools designs and manufactures Morpholino antisense oligos (PMOs). Morpholinos bind to complementary RNA and get in the way of processes such as translation, splicing and miRNA activity. Morpholinos are the premier knockdown tools used in developmental biology labs, the best RNA-blocking reagents for cells in culture and, as Vivo-Morpholinos, the most specific delivery-enhanced oligos available for animal models. Backed by Ph.D.-level customer support, Gene Tools sells research quantities of Morpholinos world-wide.
