"Stem Cell Keep" is a vitrification freezing solution for primate ES/iPS cells that allows for the cryopreservation of stem cells while maintaining their pluripotency (undifferentiated state). It is optimized to maintain high vitrification capability while minimizing cytotoxicity. By using the vitrification method, cells can be cryopreserved in their colony form. Additionally, it is a product that does not contain DMSO or animal-derived protein components. 【Features】 ■ Does not contain DMSO or animal-derived protein components ■ Allows for cryopreservation in colony form using the vitrification method ■ Can cryopreserve stem cells while maintaining their pluripotency ■ Efficiently cryopreserves ES/iPS cell colonies ■ When used according to the protocol, it can preserve up to 100 vials *For more details, please refer to the related links or feel free to contact us.

"Seriokeeper" is a DMSO-free preservation solution for skin and nerve tissues that can maintain the membrane morphology of physically fragile tissues and retain proliferation functions for 1 to 2 weeks under refrigeration. It is applicable not only to humans, mice, and rats but also to a wide range of mammalian tissues. In an unopened (pre-preparation) state, it can be stored at 4°C for about one year. 【Features】 - Preserves thin and fragile tissues due to the protective effect of green tea polyphenols. - Usable for epithelial and endothelial tissues, as well as nerve tissues. - Preserved tissues can be used for various experiments with appropriate media after washing. - Confirmed to be free of bacterial, fungal, and mycoplasma contamination through sterility testing. - In an unopened (pre-preparation) state, it can be stored at 4°C for about one year. *For more details, please refer to the related links or feel free to contact us.

"Cryoscalis DMSO-Free" is a cell freezing preservation solution that allows for approximately 90% survival rate even after thawing, while maintaining the differentiation potential of stem cells during cryopreservation. It does not contain proteins or DMSO and can be stored stably at 4°C for long periods. Due to the absence of toxicity from DMSO and the influence of proteins, cells can be cryopreserved safely with a high survival rate. 【Features】 ■ Contains no serum or protein components ■ Approximately 90% survival rate even after thawing ■ Stem cells can be cryopreserved while maintaining their differentiation potential ■ Confirmed to be free from bacterial, fungal, and mycoplasma contamination through sterility testing ■ Can be stored stably at 4°C for long periods *For more details, please refer to the related links or feel free to contact us.

"Stem Cell Keep" is a vitrification freezing preservation solution optimized to maintain high vitrification ability while minimizing cytotoxicity, specifically designed for primate ES/iPS cells. Thanks to the high cell protection effect of a novel cryoprotectant with high safety and the ability to maintain a glassy state, it has become possible to freeze and preserve ES/iPS cell colonies more efficiently. 【Features】 - Does not contain DMSO or animal-derived protein components - Allows for freezing preservation of colonies through vitrification - Can freeze and preserve stem cells while maintaining their differentiation potential - Confirmed to be free from contamination by bacteria, fungi, and mycoplasma through sterility testing - Can be stored stably for long periods at 4°C (shelf life of 2 years) *For more details, please refer to the related links or feel free to contact us.
