Sample preparation


1.Sample Origin

General information:
Recombinant mucin-type proteins carrying LacdiNAc on different O-glycans

Growth/harvest conditions for recombinantly produced material:
CHO-K1 cells (Cat no CCL-61, ATCC, Manassas) were seeded in 75-cm2 T-flasks (Nunc, Roskilde, Denmark) in Dulbecco's Modified Eagle's medium (DMEM, Lonza Group Ltd., Basel, Switzerland) supplemented with 10% fetal bovine serum (FBS; Invitrogen AB, Stockholm, Sweden), 2 mM L-glutamine (Invitrogen) and 100 units/mL penicillin, and 100 µg/mL streptomycin (Invitrogen). The cells were maintained at 37oC and 5.0% CO2 in a humidified incubator.
