About Kuraray’s microcarriers
PVA Microcarriers are polyvinyl alcohol (PVA)-based microcarriers developed by Kuraray. The high transparency of the PVA hydrogel enables clear observation of cells. In addition, due to the nature of the material, PVA hydrogel is resistant to mechanical impacts like stirring, and the risk of contamination from fragments can be reduced. Two product options are available. PVA Microcarriers CL features a Type I collagen-modified surface, while PVA Microcarriers AS features an activated surface that can be coated with selected cell-adhesion molecules.
Ease of handling
PVA Microcarriers are supplied ready to use. No additional sterilization or washing is required before use. The microcarriers hydrate rapidly in PBS or culture medium and become highly transparent. This transparency facilitates clear cell observation using phase-contrast microscopy.

Safety testing
PVA Microcarriers are manufactured and quality-controlled under an ISO 9001-certified quality management system. Due to the nature of the materials, it is resistant to mechanical impacts like stirring, which helps reduce the risk of foreign matter contamination from broken pieces.
