Dialyzed Fetal Bovine Serum (D-FBS)

Dialyzed Fetal Bovine Serum (D-FBS) provides more consistency among the cell culture experiments, especially the studies requiring a more defined environment of small molecules. The dialysis process eliminates/ reduces the concentration of low molecular weight components such as antibiotics, nucleotides, amino acids as well as hormones

Description

Background

Dialyzed Fetal Bovine Serum (D-FBS) provides more consistency among the cell culture experiments. That especially stands out in studies requiring a more defined environment of small molecules. moreover, The dialysis process eliminates/ reduces the concentration of low molecular weight components. That includes antibiotics, nucleotides, amino acids, hormones, salts, as well as various small proteins in the serum.

PurMaTM Dialyzed FBS is Free of Tetracycline and other Antibiotics.

PurMaTM Dialyzed FBS (DFBS)

  • PurMaTM Premium FBS is USA origin.
  • We perform the dialysis using the 3500 Dalton (3.5 kDa) dialysis tube. The procedure carries out against 10X 10-liter PBS (pH 7.4). At the end, the dialyzed FBS sterilized  by 0.1 µM filters for three times.
  • The parent FBS Has gone through gamma irradiation as well as heat inactivation process.
  • PurMa Biologics performs vigorous analysis following the dialysis which results in  and certificate of analysis.
  • Free of Mycoplasma, steroids and hormones, and other pathogens.
  • Acceptable level of endotoxin (10 mg/Dl) and hemoglobin (20 mg/Dl).
  • Due to the loss of small growth factors and other essential elements below the size of 3.5 kDa we recommend using 15-20% DFBS in your media to make sure of cultured cell well beings.
