  • Patent number: 7718579
    Abstract: A method for electrochemical removal of acid-labile protecting groups on an electrode microarray using an organic solution is disclosed. The solution comprises a hydrazine derivative and a salt in an organic solvent. The hydrazine derivative has at least one hydrazine group having at least one hydrogen. The hydrazine derivative provides acidic reagent when an electrode is active and isolates the acidic reagent to the area around the active electrode. The salt is an organic salt or ionic liquid having a concentration sufficient to provide electrochemical conductivity under an applied voltage. During the applied voltage, acidic reagent is generated, which removes acid-labile protecting groups thereby allowing continued addition of monomers to build a custom microarray of oligonucleotides, peptides, or other polymers.

  • Patent number: 7541314
    Abstract: 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.

  • Publication number: 20080039342
    Abstract: There is disclosed a process for performing an isolated Pd(0) catalyzed reaction electrochemically on an electrode array device. Specifically, there is disclosed a process for conducting an isolated Pd(0) catalyzed reaction on a plurality of electrodes, comprising providing an electrode array device having a matrix or coating material over metallic or conductive electrodes surfaces and a plurality of electrodes; providing a solution bathing the electrode array device, wherein the solution comprises a transition metal catalyst and a confining agent; and biasing one or a plurality of electrodes on the electrode array device with a voltage or current to regenerate the transition metal catalyst required for the isolated Pd(0) catalyzed reaction, whereby the confining agent limits diffusion of the transition metal catalyst to a volume surrounding each selected electrode surface.

  • Publication number: 20070037169
    Abstract: The present invention provides a method for selective dehybridization by electrochemically-generated (ECG) reagent on an electrode microarray. The ECG reagent is generated by activation of selected electrodes. Activation alters pH in the vicinity of only the selected electrodes. In one embodiment, the increase or decrease in pH is sufficient to cause dehybridization of an oligonucleotide duplex at the selected electrodes. In another embodiment, the increase or decrease in pH is sufficient to prevent chemical dehybridization at the selected electrodes. The dehybridized single stranded target oligonucleotide may be recovered and amplified by PCR.
