Basic Media

September 8, 2004 7:05 am | Articles | Comments

Miltenyi Biotec has recently introduced the MACS basic media product line comprising RPMI and DMEM with classical formulations and modifications thereof with stable glutamine. RPMI and DMEM are used for a broad spectrum of applications.

Competent Cells (3929)

September 8, 2004 7:05 am | Articles | Comments

Chemically competent E.coli cell lines have been developed using a proprietary process that both improves and maintains transformation efficiencies of the cells in single-shot tubes and 96-well plates. The process has been applied to strains of BL21, DH5Alpha and JM109.

Tissue Culture Dishes (3917)

September 8, 2004 7:05 am | Articles | Comments

CellStar dishes are manufactured from the virgin polystyrene and offer distortion-free optical clarity. Dishes are available in 35 × 10, 60 × 15, 94 × 16, 100 × 20 and 140 × 20mm formats. Lids are vented to provide uniform gas exchange and reduce condensation.

Reduced Serum Media Formulations

September 8, 2004 7:05 am | Articles | Comments

Gibco Advanced D-MEM/F-12 and Advanced RPMI 1640 reduced serum media formulations enable researchers involved in mammalian cell culture to reduce Fetal Bovine Serum (FBS) supplementation by 50 to 90 percent with little or no change in cell growth, promotion, morphology or function.

Heavy Wall Filter Flasks

September 8, 2004 7:05 am | Articles | Comments

Kimble and Kontes have upgraded all of their filter flasks, which now feature a heavier, more uniform bead for less chipping and maximum durability. Heavier walls mean less chance of breakage during vacuum filtration. Beaded bottoms increase scratch resistance.

Bioreactor Applications Reports

September 8, 2004 7:05 am | Articles | Comments

New Brunswick Scientific has published a series of application reports on the use of their benchtop BioFlo 110 fermentor/cell culture system. Five studies document step-by-step procedures for culturing Chinese Hamster Ovary (CHO), hybridoma and insect cells, as well as E. coli and Pichia pastoris.

Large Capacity Flask

September 8, 2004 7:05 am | Articles | Comments

New 225 cm 2 NUNC EasYFlask is equipped with a system that allows opening or closing the flask by a mere one-third turn of the cap. Maximum airflow underneath the flask optimizes temperature equilibration during incubation, even when stacked.
