title: [A new blocking method for DNA chip].
abstract: Suggested a new blocking method for DNA microarray: 1-iodo-propane. We compared the difference between the two block reagents and the blocking results in different blocking time. The results showed that 1-I-propane is batter-blocking reagent than succinic anhydride in DNA chip. 1h blocking time is enough for blocking.
