Abstract
Official abstract text for this publication.
Provided is a device for vitrification-based cryopreservation which enables easy and reliable vitrification freezing of cells or tissues. The device of the present invention for cell or tissue cryopreservation by vitrification has a porous structure made of a material having a refractive index of 1.45 or less as a vitrification solution absorber.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for cryopreserving eggs or embryos by vitrification, the device comprising a vitrification solution absorber having a porous structure made of a material having a refractive index of 1.45 or less, wherein after a cell or tissue immersed in a vitrification solution is placed on said vitrification solution absorber, the vitrification solution absorber absorbs excess vitrification solution surrounding the cell or tissue, the diameter of the largest opening of the porous structure measured according to the method for bubble point testing specified in JIS K3832 is 0.75 μm or less, and a thickness of the porous structure is 25 to 150 μm. 2. The device according to claim 1 , wherein the porous structure is made of fluororesin. 3. The device according to claim 1 , wherein the diameter of the largest opening measured according to the method for bubble point testing specified in JIS K3832 of the porous structure is 0.02 to 0.75 μm. 4. The device according to claim 1 , wherein the diameter of the largest opening measured according to the method for bubble point testing specified in JIS K3832 of the porous structure is 0.2 to 0.75 μm. 5. The device according to claim 2 , wherein the diameter of the largest opening measured according to the method for bubble point testing specified in JIS K3832 of the porous structure is 0.02 to 0.75 μm. 6. The device according to claim 2 , wherein the diameter of the largest opening measured according to the method for bubble point testing specified in JIS K3832 of the porous structure is 0.2 to 0.75 μm.
