bioGenous™ Primary Tissue Storage Solution (Serum-free) is designed to optimize the short-term storage and transport of primary tissue samples, especially when material needs to be collected from multiple sources or at different time points, or when immediate processing is not possible. This solution effectively prevents necrosis and apoptosis during the storage period, ensuring the preservation of cell functionality, including the activation and pluripotency status of stem cells. The solution maintains the viability of most cells within primary tissue samples for over 48 hours at 2°C-8°C, significantly reducing cellular loss between sample collection and experimental initiation, thereby improving the success rate of establishing primary tissue cultures. bioGenous™ Primary Tissue Storage Solution is widely applicable for the preservation and transport of primary samples from solid tumors and normal tissues of mammals such as human and mice prior to in vitro primary culture.
