Ten micrograms of genomic DNA was digested with each enzyme (BamHI, BamHI/HindIII, EcoRI, and BgIII; Gibco-BRL, Gaithersburg, Md) in the following reaction mixture: 10 [micro]g of DNA, sterile double-distilled water to 39 [micro]L total, 5 [micro]L of 10x buffer, 4 [micro]L of restriction enzyme (50 units/[micro]L stock), and 2 [micro]L of 0.1 mol/L spermidine (Sigma Chemical Co, St Louis, Mo).
Total DNA samples were digested according to manufacturer's specifications, with the addition of spermidine (0.1 mM final concentration) to facilitate completion of enzymatic digestion.
