Lentiviral vectors are now recognised as an efficient transgene delivery system which can result in greater than 90% of founder animals carrying the transgene. Vector injection into the perivitelline space has emerged as the standard delivery method but is limited by the need for high-titre lentivirus vector preparations. Based on a modified perivitelline injection method we demonstrate that transgenic animals can be generated from low-titre virus vector preparations further simplifying lentiviral transgenesis. Repeat injection of 10(7) TU/ml vector preparation resulted in 23% of embryos carrying the transgene compare to 1% from a single injection. Embryos exposed to repeat injection of vector developed to blastocyst with the same efficiency as non-injected embryos and produced transgenic mice capable of transmitting the transgene through the germline.
