Dialyzed Fetal Horse Serum (DFHS)
Dialyzed Fetal Horse Serum (DFHS) 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, those include; antibiotics, nucleotide, amino acids, hormones, salts, as well as various small proteins in serum.
Description
Background
Animal serum contains many undefined components. PurMa™ Dialyzed Fetal Horse Serum (DFHS) 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. That includes antibiotics, nucleotide, amino acids, hormones, salts, and various small proteins in serum.
PurMaTM Dialyzes- FHS is Free of Tetracycline and other Antibiotics.
PurMa™ Dialyzes FHS (DFHS)
- DFHS has been dialyzes using the 3500 Dalton (3.5 kDa) dialysis tube. The dialysis is carried out against 10X 10-liter PBS (pH 7.4). at the end, the dialyzed FHS is filtered three times (0.1 µM filters).
- PurMa™ Dialyzed Fetal Horse Serum (DFHS) is USA origin.
- The parent DFHShas been gamma irradiated.
- Following the dialysis, the FHS goes through heat inactivation process.
- Following the dialysis, the FHS goes through vigorous analysis and will get a certificate of analysis.
- Moreover, PurMa™ Dialyzed Fetal Horse Serum (DFHS) is free of Mycoplasma, steroids and hormones and other pathogens.
- PurMa™ DFHS is free of endotoxin and also contains Acceptable level of 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% DFHS in your media to make sure of cultured cell well beings.
Further Instructions
On receiving the bottle or on first usage, defrost and aliquot the bottle into smaller quantities as freezing and thawing is not recommended for this product.

Review: I have worked directly with PurMa biologics on a number of projects ongoing in my lab. I find the media and the specialty Lipid Depleted Serum to be high quality and very consistent among batches, which is critical to our adipogenesis projects using primary stem cells. Also, the service from PurMa is outstanding for my lab.
