Collected from the source: When searchers choose their serum an important factor that should be taken into consideration is the source, which also emphasises the traceability of the serum. Our system of vertical integration allows us to be certain of the origins and traceability of our serum Each batch is rigorously controlled, from the collection of serum, and in all the stages of its treatment and production on our premises through to final packaging. Biosera Rabbit Serum is derived from clotted whole blood collected from rabbits, via the Jugular vein. The serum is collected in EC approved slaughterhouses. Filtration: Final Filter Size: 0.2μm, x 2 Sterility: All sera are tested for the absence of aerobic and anaerobic bacteria, fungi, yeast and Mycoplasma. The sterility test is based on the European Pharmacopoeia requirements. The sera are tested for the absence of Mycoplasma after 21 days of culture. Endotoxin: All sera are tested to determine the levels of endotoxins. Biosera carries out a chromokinetic test (quantitative test). The endotoxin reagent is standardized against the US reference endotoxin. The method is based on "the bacterial endotoxins test", US pharmacopeia 23rd revision. Haemoglobin: The haemoglobin level is measured by spectrophotometer. Osmolarity: Determined by a lowered freezing temperature. The osmometer is calibrated against standard solutions
