Description
Background
PurMa Biologics manufactures seven types of horse serum, three of which, including PurMaTM Endotoxin-Depleted Fetal Horse Serum (ED-FHS) are considered as premium fetal Horse serums, each specialized for certain requirements in tissue culture:
- PurMa™ Premium Fetal Horse Serum (P-FHS).
- PurMa™ Ultra-Premium Fetal Horse Serum (UP-FHS).
- PurMa™ Endotoxin-Depleted Fetal Horse Serum (ED-FHS).
Additionally, PurMa™ Endotoxin-Depleted Fetal Horse Serum (ED-FHS) is processed from PurMa™ Premium Fetal Horse Serum (P-FHS). It, therefore, provides an excellent opportunity to compare the two serums from an endotoxin perspective.

Endotoxin Removal
Purma Biologics removes the endotoxin from FHS by passing the premium FHS through the PurMa™ Endotoxin Elimination Column (Cat# P6H1216251). The Sepharose 6B in our proprietary column is covalently conjugated to an endotoxin-specific absorbent. The mentioned procedure follows by eliminating the residual endotoxin by passing the unbound fraction three times through 0.1µm filters.
