Table 1.
Cytotoxicity gradation | RGR (%) |
---|---|
Band 0 | ≥100 |
Band 1 | 75∼99 |
Band 2 | 50∼74 |
Band 3 | 25∼49 |
Band 4 | 1∼24 |
Band 5 | 0 |
Notes: The RGR was calculated as follow: ODtest cells/ODnegative control × 100%. The band 0 or 1 was qualified, band 2 should be evaluated with morphology, and band 3∼5 was unqualified.23
Abbreviations: OD, optical density; PMBCs, peripheral blood mononuclear cells; RGR, relative growth rate.
