摘要:
There is disclosed a microarray having base cleavable linkers and a process of making the microarray. The microarray has a solid surface with known locations, each having reactive hydroxyl groups. The density of the known locations is greater than approximately 100 locations per square centimeter. Optionally, oligomers are synthesized in situ onto the cleavable linkers and subsequently cleaved using a cleaving base. Optionally, the oligomers are cleaved and recovered as a pool of oligomers.

摘要:
The present invention provides a microarray having base cleavable, sulfonyl-containing linkers and a process to make the microarray. Oligonucleotides of any sequence may be synthesized on the microarray having the cleavable linker. The oligonucleotides may be cleaved and recovered as a pool of oligonucleotides having a three prime phosphate moiety. Specifically, the microarray is an electrode containing microarray, and the oligonucleotides are electrochemically synthesized.

摘要:
There is disclosed a microarray-based single nucleotide polymorphism, sequencing, and gene expression assay method. Specifically, there is disclosed a method using a microarray device wherein a plurality of hybridized structures is formed by contacting the microarray under a hybridizing condition to a hybridizing solution comprising a plurality of tagged targets and a plurality of detection sequences. The detection sequences of each hybridized structure is extended using an extension-ligation solution and an extension-ligation condition. After extension, ligation of the extended sequence occurs to a probe if the terminal nucleotide of a probe is complementary to the hybridized tagged targets. Non-bound material is removed by using a washing solution and a washing method. The target nucleotide and the target sequence of the tagged targets is determined by which probe is ligated to the detection sequences.
