The Quick-Ray product line is for use in the Histopathology laboratory to fabricate Tissue Micro-Arrays. The Quick-Ray set are principally used for research purposes. The Quick-Ray set comes with one puncher, 4 tips of each size, and 1 recipient block of each size, and a base mold (to hold the recipient block while the tissue cores are transferred to it), guide for 1mm recipient block. A tissue puncher with changeable tips of different diameters. Currently, 4 sizes are available: 1, 2, 3, and 5 mm in diameters. The puncher allows the user to retrieve cylindrical cores of tissues from donor tissues embedded in paraffin blocks. The cores are then distributed into a single use recipient block. The patented recipient block is made of a special material that melts when heated at about 70oC for 30~60 minutes. The recipient block has pre-made, evenly spaced round orifices (wells) arranged in a square matrix (array). Four different recipient blocks are currently available: 10 x12 wells of 1mm in diameter 6 x10 wells of 2mm in diameter 5 x 6 wells of 3mm in diameter 4 x 5 wells of 5mm in diameter Portable Low cost Easy to handle Shortening Tissue Array block production time Minimized size Arrayer comparing with the conventional products Easy to carry and to make the array block anytime and anywhere Inexperienced pathologist can handle easily in the lab. Simple developing procedure Easy to create the various sized blocks with using the disposable bases Steel array block and Cassette array block are available in situ hybridization FISH Special stain Immunohistochemistry
