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.

Microarray having a base cleavable linker

Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules having one or more members of a reactive pair are disclosed which can be used to increase the number of intra-complex binding interactions in a complex comprising a target molecule and a substrate. Intra-complex crosslinking and inter-complex crosslinking can be utilized in connection with these methods and compositions to further strengthen and stabilize the disclosed binding complexes.

Highly reactive functionalized substrates and linker molecules for use in the detection of molecular targets and other analytes of interest are provided as are kits, reaction mixtures and methods utilizing the same.

Methods and compositions for the target-localized anchoring of detectable label

Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules are disclosed which can be used to increase the number of intra-complex binding interactions. Covalent bonds can be introduced to further increase the strength of these binding interactions. Inter-complex cross-linking can be utilized in connection with these methods to further strengthen and stabilize the disclosed binding complexes.

Methods and compositions in particle-based detection of target molecules using linking molecules

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.
