WebTransgenic embryos produced by pronuclear injection showed a discrete pattern of GFP expression with clusters at 25, 50, and 100% of blastomeres expressing GFP. This pattern of mosaicism is interpreted to indicate that the integration of microinjected DNA occurred, not only at the pronuclear stage, but also in the subsequent cell divisions. WebThe facility requires at least 30ul of DNA fragment at a concentration of at least 50ng/ul. The more concentrated the better, but aim for quality over quantity!
