Cell culture laboratories use FHS\u00a0 for various purposes. P-FHS contains undefined nutrition, growth factors as well. Therefore, it remains a widely used supplement for cell culture. PurMa Biologics has developed and processes three main premium fetal horse serums, each specialized for certain requirements in tissue culture.<\/p>\n<h3>Our Serum Products<\/h3>\n<p>PurMa Biologics produces seven types of horse serums. The three following are considered premium:<\/p>\n<ul>\n<li>PurMa\u2122 Premium Fetal Horse Serum (P-FHS).<\/li>\n<li>PurMa\u2122 Ultra-Premium Fetal Horse Serum (UP-FHS).<\/li>\n<li>PurMa\u2122 Endotoxin Depleted Fetal Horse Serum (EDP-FHS).<\/li>\n<\/ul>\n<h3>PurMa\u2122 Premium FHS<\/h3>\n<ul>\n<li>All three PurMa\u2122 Premium FHS are, indeed, of USA origin.<\/li>\n<li>We additionally sterilize FHS by gamma irradiation.<\/li>\n<li>Have been heat inactivated.<\/li>\n<li>PurMa Biologics vigorously analyzes all bovine and horse serums and, that results in a certificate of analysis for each Lot.<\/li>\n<\/ul>\n<h3>The major differences between P-FHS and UltraPremium Fetal Horse Serum UPFHS<\/h3>\n<ul>\n<li>The source of the Blood and therefore:<\/li>\n<li>Significantly higher growth by Ultra-Premium Fetal Horse Serum (UP-FHS) compared to P-FHS, which determines the potency of the serum.<\/li>\n<li>The depth of the analysis:<\/li>\n<li>Quality of PurMa\u2122 Premium Fetal Horse Serum (P-FHS)<\/li>\n<\/ul>\n<p>Over the years, we have tested and analyzed PurMa\u2122 Premium Fetal Horse Serum (P-FHS).
