The invention discloses a dedicated centrifugal tube and method for
manufacturing cell blocks. The dedicated centrifugal tube is composed of a cylindrical centrifugal
pipe with two opened ends and two centrifugal tube covers. The surfaces of the
pipe walls of two ends of the centrifugal tube are provided with external threads, the centrifugal tube covers are covers with a flat bottom, the bottoms of the covers are provided with a sealing ring (
cushion), the internal walls are provided with internal threads, and the internal threads and the external threads can be engaged together to form a sealed cylindrical space. The
cell block is produced by the following steps: heating a centrifugal tube containing matrix to liquidize the matrix, then adding
cell (cluster) suspension on the upper surface of the matrix layer, turning the centrifugal tube upside down to mix the matrix and the
cell suspension, then carrying out
centrifugation, (or directly carrying out
centrifugation), so as to enrich the cells to a plane on the bottom layer of the matrix through the matrix (
cushion); after the matrix is cured, removing the centrifugal tube cover on the two ends of the centrifugal tube, pushing out the matrix containing a
cell layer by a
piston or pressurized air from the centrifugal tube, and
cutting the matrix to manufacture cell blocks. The provided method can conveniently and efficiently make trace cell samples into a complete and regular
cell block with a
large cell distribution area and
high cell density.
