A method of constructing a polynucleotide microarray whereby a sufficient amount of polynucleotide can be immobilized on a support and thus a uniform and strong signal can be obtained in a spot area even in the case of synthetic oligopolynucleotides which are known as being hardly immobilized via electrostatic bonds because of short chain length. Namely a method of , constructing a polynucleotide microarray characterized in that a solution in which a polynucleotide is dissolved in the step of immobilizing the polynucleotide on a support comprises water or a mixture of water with an organic solvent and is substantially free from any anionic electrolytes and, in case where the solution …

Why it's free to use
- Filed May 10, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 10, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
