My question is whether I can infiltrate Cy3-labelled ssDNA or siRNA into intact plant leaves without carriers (agrobacterium or gene gun) and still have a chance to see fluorescence through a confocal microscope? IF YES, without a carrier, how come ssDNA or siRNA will deliver and show fluorescence? IF NO, what is the reason? Your response is highly helpful to me. Thanks in advance for your answers or responses.
