Device for collection, storage, retrieval and shipping of hair follicles from animals
View Patent ↗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 method for collecting and analyzing nucleic acid of a hair follicle sample comprising: obtaining a hair follicle sample; placing the hair follicle sample on low tack adhesive of a device comprising a clear plastic cover that is layered on a base sheet forming opposing clear plastic cover and base sheet surfaces, wherein one or both of the opposing surfaces comprises a low tack adhesive; removing all or a portion of the hair follicle sample; and subjecting the sample to nucleic acid isolation and/or analysis, whereby the hair follicle sample is punched out through the clear plastic cover and base sheet before isolation and/or analysis.
2. The method of claim 1 , wherein the base sheet is touch cut to form a grip for separating the clear plastic cover from the base sheet.
3. The method of claim 1 , wherein the base sheet is filter paper.
4. The method of claim 1 , wherein the base sheet is plastic.
5. The method of claim 1 , wherein the base sheet is clear plastic.
6. The method of claim 1 , wherein the base sheet is paper.
7. The method of claim 6 , wherein the paper is coated with a chemical that is a biological buttering agent.
8. The method of claim 6 , wherein the paper is fingerprinting paper.
9. The method of claim 1 , wherein the device further comprises an outer cover forming flaps.
