产品型号：GM-J#003328 -Cryorecovery

产品应用：A cre recombinase coding sequence, driven by the mouse protamine 1 promoter (Prm) in this transgenic strain, mediates the efficient recombination of a cre target transgene in the male germ line, but not in other tissues. The use of embryonic stem cells of this strain can substantially simplify the production of subtle or conditional mutations in mice.
