LoSera™ Dulbecco’s Modified Eagle Medium/Nutrient Mixture F-12 Ham (DMEM/ F12, 1:1 Mixture)
With L-Alanyl-L-Glutamine, HEPES buffer, Sodium bicarbonate and Trace elements
1X Liquid Cell Culture Medium requiring reduced serum supplementation

Product Code: HM-RSL006G

Product Description:

LoSera™ media are based on the classical formulations supplemented with insulin, transferrin and other advanced nutrients. The additional nutrients help in reducing the percentage of serum required to grow most of the common cell lines. The percentage of serum reduction may vary with type of cell line used. For nonfastidious cell lines serum can be reduced from 10% to as low as 1%. For fastidious cell lines serum usage can be reduced from 10% to 2.5%. LoSera™ medium can be used without prior adaptation and sub cultured using normal procedures. Reduced serum supplementation improves the reproducibility of experimental results by decreasing the variability caused due to undefined serum constituents. It also facilitates down regulation process in bioassays and in purification process of culture products.

RSL006G is LoSera™ DMEM/Nutrient Mixture F-12 Ham with trace elements, sodium bicarbonate and HEPES buffer. HEPES, a zwitterionic buffer having a pKa of 7.3 at 37ºC prevents the initial rise in pH that tends to occur at the initiation of a culture and increases the buffering capacity of the medium. It does not contain L-glutamine. Users are advised to review the literature for recommendations regarding medium supplementation and physiological growth requirements specific for different cell lines.

Recommendations for use with LoSera™ Media:
  1. LoSera™ media have been optimized at 2.5% serum concentration for a broad range of cell culture applications. Recommended concentrations of serum using LoSera™ media ranges from 1-5%. However the concentration of serum used may need to be adjusted for specific cell types or applications to achieve optimal results. Titration of FBS concentration is recommended to determine maximum serum reduction.
  2. In case of antibiotics being used to control contamination, it is recommended to reduce the amount of antibiotics in proportion to the amount of serum reduced.

Material required but not provided:
  • Fetal Bovine Serum (RM1112/RM10432)

Quality Control:
  • Appearance: Red colored, clear solution.
  • pH:7.00 -7.60
