PEG is used as a fusogen to obtain hybridomas for monoclonal antibody production. Induces cell hybridization.

Recommended for use in a normal fusion protocol requiring 50% PEG and 10% DMSO.


Packaged in sealed ampules under nitrogen.

Other Notes

Contains 50% (w/v) polyethylene glycol (Av. Mol. Wt. 1450) and 10% DMSO (v/v) in DPBS without Calcium.


Solution is ready-to-use. If a less concentrated solution is desired, dilute with sterile DPBS without calcium (D5773). Some precipitate may appear after being exposed to cooler, but should disappear as the solution warms. Solution may be frozen if desired but should first be aliquotted to avoid repeated freeze/thaw cycles.
