Abstract
A device particularly suited for constructing frozen tissue microarrays. The device comprises: a cooling chamber for receiving at least one frozen material and for maintaining the frozen material in a frozen condition; the cooling chamber moveable in an x and y direction relative to a horizontal surface; at least one coring needle comprising a cutting surface and a lumen for receiving a core of frozen material cut by the cutting surface; and at least one coring needle positioning element, for positioning the at least one coring needle over said frozen material for cutting said frozen material. Frozen tissue microarray blocks and methods of generating these are also provided.
