DNA CHAIN ELONGATION METHOD, DNA CHAIN AMPLIFICATION METHOD AND MICROARRAY FOR DNA CHAIN ELONGATION

摘要

A primer for DNA elongation is immobilized to a substrate having a polymer, which comprises a first unit having a group induced from a phosphate constituting the hydrophilic moiety of a phospholipid and a second unit having an active ester group, on its surface. Then, a reaction system, into which a template DNA fragment having a desired sequence and a sample containing a nucleotide monomer have been introduced, is heated to a temperature at which the DNA chain is thermally denatured. Next, the temperature of the above reaction system is lowered to a temperature for performing an annealing treatment and the DNA chain elongation is carried out in this reaction system.
