We have been using Gibco RPMI 1640 + L-glutamine (catalogue # 11875093), however our supplier recently increased the price AND added a handling charge.
I have found Lonza BioWhittaker RPMI 1640 + L-glutamine (BW12-702F Lonza 12702F) at much more reasonable prices. One of our post-docs is quite hesitant to try it. Does anyone have experience using this supplier for cell media?
