Materials Sold Separately

• NEB® 10-beta/Stable Outgrowth Medium

1. STORAGE AND HANDLING: Competent cells should be stored at -80°C. Storage at -20°C will result in a significant decrease in transformation efficiency. Cells lose efficiency whenever they are warmed above -80°C, even if they do not thaw.
2. CAUTION: This product contains DMSO, a hazardous material. Review the MSDS before handling.
