Substantial amounts of DNA (at least 25 microgram per cm2) can be stably bound to diazobenzyloxymethyl (DBM)-paper. Complementary RNA will hybridize to the DNA paper almost completely in 24 hours. Using several different conditions of hybridization and washing, the background of RNA bound non-specifically is very low (between 0.01 and 0.02%) and the efficiency of hybridization is very high (75 to 50% of complementary RNA is bound and retained through the washing procedure). Because the DNA is bound to the paper convalently, it is retained through all the washing and elution steps, and the DNA papers can be re-used many times.
大量的DNA(每平方厘米至少25微克)能够稳定地结合到重氮苄氧基甲基(DBM)纸上。互补RNA在24小时内几乎能与DNA纸完全杂交。使用几种不同的杂交和洗涤条件,非特异性结合的RNA背景非常低(在0.01%至0.02%之间),杂交效率非常高(75%至50%的互补RNA在洗涤过程中被结合并保留)。由于DNA与纸共价结合,它在所有洗涤和洗脱步骤中都能保留下来,并且DNA纸可以多次重复使用。
