Device for collection, storage, retrieval and shipping of hair follicles from animals
The present invention relates to a novel device for the collection, storage, shipping and retrieval of hair follicles from animals for the purpose of isolating DNA or other genetic material from the follicles for analysis. The device has outer flaps for the protection as well as identification of the samples and an inner part where samples are placed. The inner device has thicker base and a clear plastic cover, the easy peel back of which is facilitated by a) low tack adhesives that hold the two together and b) a touch cut on one end, through the base sheet which creates a grip. This makes the device convenient and easy to use, and yet a robust collection device for hair follicles from animals in a farm or real-life situation. Hair follicles can be punched out through the inner device for direct DNA isolation and analysis.
1. A collection device for collecting biological samples comprising:
(a) a top flap;
(b) a bottom flap coupled to the top flap at a seam; and
(c) an inner device disposed between the top flap and the bottom flap and coupled to one or both of the top flap and the bottom flap at a region proximate to the seam, the inner device comprising a base and a top sheet, the top sheet being fixedly coupled to the base at a region proximate to the seam and the top sheet being partially separably coupled to the base at a region comprising substantially all of an area of overlap of the base by the top sheet and extending away from the seam;
wherein:
(i) the top sheet is partially separably coupled to the base by an adhesive extending over substantially all of the area of overlap of the base by the top sheet,
(ii) the top sheet comprises a grip extending in a direction distal to the seam,
(iii) the grip is positioned at a distal end of the top sheet relative to the seam,
(iv) the base comprises (A) a first portion proximal to the seam and fixedly coupled to the top sheet at the region proximate to the seam and (B) a second portion distal to the seam and separated from the first portion of the base,
(v) the grip comprises the second portion of the base coupled to the top sheet by the adhesive at the distal end of the top sheet relative to the seam, and
(vi) the top sheet and base are configured to be punched out to provide portions of the top sheet and the base with a portion of the biological sample disposed therebetween.
2. The collection device of claim 1 , wherein the top sheet comprises a clear plastic.
3. The collection device of claim 2 , wherein the base comprises a plastic that is more rigid than the clear plastic of the top sheet.
4. The collection device of claim 1 , wherein the base comprises paper.
5. The collection device of claim 1 , wherein the biological sample is an animal sample.
6. The collection device of claim 1 , wherein the inner device is coupled to one or both of the top flap and the bottom flap by an adhesive.
7. The collection device of claim 1 , wherein an outer surface of one or both of the top flap and bottom flap comprises a unique identifier for the collection device.
8. The collection device of claim 7 , wherein the unique identifier comprises a machine readable barcode.
9. The collection device of claim 1 , further comprising a hair follicle sample fixed by the adhesive in the inner device between and in contact with both the base and the top sheet of the inner device.
10. The collection device of claim 1 , wherein:
(i) the inner device is coupled to the top flap and the bottom flap; and
(ii) the top sheet cannot be completely removed from the base sheet.
11. The collection device of claim 1 , wherein the collection device comprises only a single inner device between the top flap and the bottom flap.
