Tripeptide, Arg-Gly-Asp, inhibits the transfection of protein-linked DNA of bacteriophage M2

The effect of tripeptide, Arg-Gly-Asp (RGD), on the transfection activity of Bacillus phage M2 DNA was examined. The transfection activity decreased when M2 DNA was preincubated with RGD before it was added to competent cells.
