Abstract
Devices, methods, and kits directed towards collecting and preparing cells using a separable sample collection layer may be configured to collect or treat cells from a liquid sample with mechanisms for easy transfer of the cells prior to analysis or imaging. The separable sample collection layer may comprise a porous membrane that cells may be collected on, and one or more support layers comprising tape with one or more adhesive coatings and release liner. The devices, methods and kits may be configured with support layers comprising cutouts that form vertically or horizontally oriented microchannels for efficiently removing undesirable liquid. Following collection and/or treatment, cells collected onto the porous membrane may be adhered to another surface for further processing or analysis.
