Application

Recommended for cell fusion.

Reconstitution

Melt the PEG at 45 °C or higher in a waterbath. Dilute to 30-50% using sterile, pre-warmed serum-free medium (e.g., for a 50% solution add 5 mL to the 5 g vial of PEG). The pH of the solution should be slightly alkaline (pink, not orange or purple). Adjustment of the pH with sterile NaOH may be required. Store solution below 0 °C. Prolonged storage or repeated freezing and thawing is not recommended.
