Exchangeable GFP Expressing Stable CHO Cell Line (CHO-B4)

Description

This cell line, known as CHO-B4, has a landing pad integrated at a single locus enabling extended, stable, GFP expression. Using the phiC31 recombinase, a Herceptin expression cassette was introduced and this was also found to allow stable expression. Successful integration of your target expression cassette can be confirmed by the absence of GFP expression following transfection.
