Cellstor-S is a cell suspension and preservation solution, and Cellstor-W is a cell wash and preservation solution manufactured by Otsuka Pharmaceutical Factory, Inc.
They are used for refrigerated and room-temperature storage. They do not contain any components of human or animal origin.

※They are reagents for research use and are not intended for medical use in humans or animals.

Features

  • Store cells at room or refrigerated temperature
  • Human and animal origin-free

How to use

Extract the solution with a needle and a syringe. The product package is not designed for cell storage. When storing cells, use a container suitable for cell storage.

Differences in Usage of Cellstor-S and Cellstor-W


  • Since Cellstor-S is formulated with dextran 40, it is not suitable for washing cells when performing centrifugation. In such cases, using “Cellstor-W” solution, which does not contain dextran 40, is recommended.

Example of Use 3

Confirmation of Adipogenic Differentiation Ability

Representative images of the adipogenesis differentiation assay with hADSCs (5×105 cells/mL) preserved in Cellstor-S and Cellstor-W after 24-hour storage at 5℃ or 25℃. Adipogenic differentiation was induced and evaluated by Oil Red O staining.

Example of Use 4

Confirmation of Osteogenesis Differentiation Ability

Representative images of the osteogenesis differentiation assay with hADSCs (5×105cells/mL) preserved in Cellstor-S and Cellstor-W after 24-hour storage at 5℃ or 25℃. Osteogenic differentiation was induced and evaluated with an alkaline phosphatase staining kit and a calcified nodule staining kit.
