DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention provides a device system for collecting, transporting, and processing a biological sample, comprising: a) a sample collection assembly; b) a collection extraction basket; c) a place holder; and 4) a hinged holder.

[0023] In certain embodiments, the sample collection assembly comprises a) a swab, b) a cap, and c) a handle comprising an area for a barcode or sample identification. In certain embodiments, the swab, the cap, and the handle, each can be detachable from each other.

[0024] As illustrated in FIG. 1, the swab (1) with or without removing the handle can be inserted into the collection extraction basket (2) and the cap provides a lid for the collection and/or extraction basket (2). In certain embodiments, the cap or lid contains a sticker or imprinted sample identification via barcode which matches removable sample identifier. In certain embodiments, the handle contains a removable sample identifier, including but not limited to, sticker or printing, which can be removed by either removal of the sticker or breaking off.

[0025] In certain embodiments, the swab is a buccal swab which can be used for collection of any cheek tissue samples, whole blood, faces, urine, skin, hair, including forensic samples.

[0026] In certain embodiments, the collection extraction basket also comprises a barcode and/or any other readable identifier which matches the sample identifier labeled on either the cap or the handle of the detachable sample collection assembly. In certain embodiments, the collection extraction basket comprising tubes having small holes at the bottom that allow for liquid to enter the collection and/or extraction basket without remove the swab.

[0027] In certain embodiments, the collection extraction basket (2) with the detachable sample collection assembly (1) can be placed for centrifugation where the biological sample on the swab is in contact with a sample processing solution. After the centrifugation, the biological sample remains in the sample processing solution while the swab can be discharged. In certain embodiments, the remaining sample processing solution comprising the biological sample can be removed from the collection extraction basket during the centrifugation if the collection extraction basket is above liquid level.

[0028] In certain embodiments, the collection extraction basket (2) with the detachable sample collection assembly (1) is used as a transport chamber for transporting and/or shipping samples collected without additional transferring steps.

[0029] In certain embodiments, the place holder (3) of the invention device system is for alignment and support between the detachable sample collection assembly (1) and the collection extraction basket (2). In certain embodiments, the place holder is made of polypropylene or other suitable polymers, glass, and/or plastic materials. In certain embodiments, the place holder is a plastic cover comprising 96 wells corresponding and/or suitable to be laid on top of a 96-deep well microtiter plate. The invention encompasses other type of plastic and/or polymer holders comprising different numbers of wells (e.g., 24 wells, 48 wells, etc.) which corresponding to and/or suitable to be laid on top of a microtiter plate with the same number of wells.

[0030] In certain embodiments, the invention device system further comprises a hinged holder (4) also comprising 96 spaces corresponding to a 96-well microtiter plate. The hinged holder allows for the detachable sample collection assembly (1) and the collection extraction basket (2) to be inserted into the spaces but limit the top of the detachable sample collection assembly (1) and the collection extraction basket (2) from fully passing through hinged holder piece (4). Once detachable sample collection assembly (1) and the collection extraction basket (2) are inserted into the place holder (3) and the hinged holder (4), the barcodes on each individual sample can be read with a 2-D barcode reader thus identifying the position of the well containing each sample.

[0031] In certain embodiments, the hinged holder (4) has two positions. When hinges are horizontal to the microtiter plate, it is in the lowered position which lowers the detachable sample collection assembly (1) and the collection extraction basket (2) containing the biological material to be in contact and/or merged with the sample processing solution pre-placed in each well of the 96-deep well microtiter plate. When hinges are extended vertically and lock into the place holder (3), it is in a raised position where the detachable sample collection assembly (1) and the collection extraction basket (2) are at the level above the sample processing solution. The device with this raised position can then be placed into a centrifuge to separate and remove the component containing the nucleic acids (e.g., DNA and/or RNA) or protein from the swab, and for further sample processing, such as DNA, RNA, or protein extraction, isolation, purification, and analysis.

[0032] The present invention 1s also described and demonstrated by way of the following examples. However, the use of these and other examples anywhere in the specification is illustrative only and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to any particular preferred embodiments described here. Indeed, many modifications and variations of the invention may be apparent to those skilled in the art upon reading this specification, and such variations can be made without departing from the invention in spirit or in scope. The invention is therefore to be limited only by the terms of the appended claims along with the full scope of equivalents to which those claims are entitled.

Examples

[0033] Using this device, the medical staff or donor will swab the donor then place the swab portion of the device in the collection basket. The identification portion from the swab is placed on the paperwork accompanying the donor's sample. The swab/basket and paperwork is then shipped to the molecular biology laboratory for testing. At receiving, the laboratory can fill a 96-deepwell plate with lysis buffer and then place the swab/basket into a detachable collection assembly without the need for identifying the well which the sample is placed into. Once fully assembled, a barcode scanner/reader can take an image of the assembled detachable collection device thus identifying the location of each sample and the corresponding well location. The detachable assembly can then be lowered into the lysis buffer to release the DNA from the cells contained on the swab. The detachable assembly can then be raised above the liquid level and then centrifuged to remove any remaining liquid absorbed by the swab. The detachable assembly can then be discarded which contains the swab sample. The DNA, RNA or protein has been transferred to the lysis buffer in the 96-well deep well plate where it can be further processed by liquid handlers or magnetic processors.

[0034] The present invention is not to be limited in scope by the specific embodiments described herein. Indeed, various modifications of the invention in addition to those described herein will become apparent to those skilled in the art from the foregoing description. Such modifications are intended to fall within the scope of the appended claims.
