The Adhesive Patch Skin Biopsy Kit is designed to reliably collect stratum corneal tissues of the skin from nearly all locations of the body with the exception of mucosals surfaces, palmar and plantar surfaces, and areas with excessive non-vellus hair (e.g scalp). This tissue can be subjected to a variety of analyses including protein, RNA, and DNA. The samples collected using the kit can be shipped to DermTech using standard FedEx overnight shipping, without the need for special storage and handling conditions. DermTech has shown that RNA suitable for analysis can be extracted from the patches for up to 8 days after sample collection with storage at ambient conditions. The shelf life of the biopsy kits is 3 years.
