Horse Serum (HS)
Laboratories across the world use Horse Serum (HS) as a growth source for many cell types In vitro. HS provides proper growth for human Embryo Fibroblast as well as models of hepatitis. PurMa Biologics collects US origin Horse Serum (HS).
Description
Background
Laboratories around the globe use Horse Serum (HS) to support the growth of many cell types In vitro. HS provides proper growth for human Embryo Fibroblast as well as models of hepatitis. Moreover, it performs well with U937 macrophage, Human lymphocytes as well as blood cells including cord blood cells, T and B lymphocytes We collect Horse Serum (HS) from foals less than 12 months old.
Horse Serum (HS) Vs. Fetal Horse Serum (FHS)
- HS Contains approximately two folds protein compared to fetal horse serum (FHS), among them, are Iggs and other antibodies.
- Contains fewer growth factors than fetal horse serum, however, is proven to be adequate for the above-mentioned cell lines.
- Importantly, it is much more cost-effective than Fetal Horse Serum (FHS).
Special Features
- PurMa™ Horse Serum (HS) has US origin.
- PurMa™ Horse Serum (HS) has been triple-filtered through 0.1 µM filters.
- PurMa Biologics sterilizes HS with gamma irradiation methodology.
- PurMa Biologics performs heat-inactivation on our HS.
- Has been tested for mycoplasma as well as endotoxin (see below), see the certificate of analysis.

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.
