Patent ID: 6900009

Claim:
A method for creating a frozen tissue array, comprising the steps of: selecting at least one frozen tissue core from a frozen tissue embedded within a donor block, said donor block held at a temperature less than the freezing point of said tissue embedded within said block; inserting each of said at least one frozen core into a compartment of a single recipient block, wherein said recipient block is held at a temperature below the freezing point of said tissue; adding an oil in a liquid form into said recipient block, wherein said oil has a freezing point lower than the freezing point of said tissue cores, said oil cooled to and added at a temperature lower than the freezing point of said tissue but higher than the freezing point of said oil thereby keeping said tissue cores frozen; and cooling said recipient block containing said oil to a temperature of about equal to or below the freezing point of said oil, thereby freezing said oil, wherein the frozen oil locks said frozen cores in said recipient block to create said frozen tissue array.
