Abstract

The "cell freezing pretreatment work plate" in the "Article to the Design" of the present application is used for pretreatment when cryopreserving biological cells such as mammalian eggs, embryos, sperm, hematopoietic stem cells, pluripotent stem cells, and other stem cells. The cell freezing pretreatment work plate has multiple recesses for treating the cells to be frozen (e.g., embryos) with various treatment solutions [ES (treatment solution containing a cell membrane-permeable cryoprotectant) and VS (treatment solution containing a high concentration of a cell membrane-permeable cryoprotectant)]. The article is entirely transparent.
