Table 1. Summary of IRI Activity and Cell Recovery Using a Panel of Polyampholytes and Polyzwitterions⁶¹.

^aStructure of the polyampholyte tested.

^bPost-thaw viability of L929 cells cryopreserved using 100 mg·mL^–1 polyampholyte, and cooling to −80 °C without controling the cooling rate.

^cIRI activity given as MLGS (mean largest grain size) and compared to a phosphate-buffered saline control. Polymers were tested at 100 mg·mL^–1.
