DEVICE FOR NUCLEIC ACID PREPARATION
First Claim
1. A device for nucleic acid preparation comprising:
- a first part defining a chamber therein and having first and second ports communicating with said chamber;
a nucleic acid extraction substrate contained within said chamber; and
a second part having a sample input port, first and second wash ports, and first and second elute ports,wherein said first and second parts are configured in operative relation with each other and are moveable with respect to each other so that (a) one of said first and second ports of said first part can be selectively aligned with said sample input port to permit a sample material to be introduced to said chamber through said sample input channel, (b) said first and second ports of said first part can be selectively aligned with said first and second wash ports to permit a wash medium to be introduced to said chamber through one of said first and second wash ports and removed from said chamber through the other of said first and second wash ports, or (3) said first and second channels of said first part can be selectively aligned with said first and second elute ports to permit an elution medium to be introduced to said chamber through one of said first and second elute ports and removed from said chamber through the other of said first and second elute ports.

Abstract
A device for nucleic acid preparation includes an outer housing and an inner housing carried within the outer housing and rotatable with respect to the outer housing. The inner housing defines an inner chamber and includes inlet and outlet ports and a nucleic acid extraction substrate within the inner chamber. The outer housing includes a sample inlet port, wash fluid inlet and outlet ports, and elute fluid inlet and outlet ports, and the ports of the inner housing can be selectively aligned with ports of the outer housing by rotating the inner housing with respect to the outer housing. By aligning one or both ports of the inner housing with the appropriate ports of the outer housing, sample material can be introduced into the chamber and wash and elution fluids can be passed through the chamber. Nucleic acid from the sample introduced into the chamber is captured on the extraction substrate and is released from the extraction substrate by sonication prior to being eluted out of the chamber.

12. A method for extracting nucleic acid from a sample within a cartridge comprising a first part defining a chamber therein and having first and second ports communicating with said chamber and a nucleic acid extraction substrate contained within said chamber and a second part having a sample input port, first and second wash ports, and first and second elute ports, wherein said first and second parts are configured in operative relation with each other and are moveable with respect to each other, said method comprising the steps of:
-
moving the first and second parts with respect to each other to align the first or second port of the first part with the sample input port of the second part; introducing sample material into the inner chamber through the sample input port and the aligned first or second inner port under conditions that will allow nucleic acid within the sample material to bind to the nucleic acid extraction substrate; moving the first and second parts with respect to each other to align the first and second ports of the first part with the first and second wash ports, respectively, of the second part; introducing wash fluid into the inner chamber through the first wash port and the aligned first port; removing wash fluid from the inner chamber through the second wash port and the aligned second inner port; applying energy to release nucleic acid from the substrate; moving the first and second parts with respect to each other to align the first and second ports of the first part with the first and second elute ports, respectively, of the second part; introducing an elute medium into the inner chamber through the first elute port and the aligned first port; and removing elute medium from the inner chamber through the second elute port and the aligned second inner port. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A genomic isolation chamber comprising:
-
a housing; a chamber within the housing; a first set of channels, wherein the first set of channels is configured to deliver a first medium to the chamber and extract a second medium from the chamber; a second set of channels, wherein the second set of channels is configured to deliver a third medium to the chamber and extract a fourth medium from the chamber; an input channel, wherein the input channel is configured to deliver a sample to the chamber; and an adsorption substrate, wherein the adsorption substrate is configured to adsorb at least a portion of nucleic acid in the sample, and wherein the genomic isolation chamber is configured so that a combination of flowing the first, second, third, and fourth mediums through or from the chamber isolates the adsorbed nucleic acid in the fourth medium. - View Dependent Claims (21)
