Bovine Fibrinogen is a blood protein of 340 kDa. Involved in clotting, Bovine Fibrinogen is converted to fibrin by thrombin.
H2B Bovine Fibrinogen is purified using Cohn fractionation and especially developed for producing RPF supplement. Bovine plasma used for the manufacture of H2B Bovine Fibrinogen is sourced in EU-approved French slaughterhouses, and is guaranteed BSE-free by French health authorities.
RPF supplement (Rabbit Plasma Fibrinogen), in addition to Baird Parker agar, is used for the detection and enumeration of coagulase-positive staphylococci in the food industry (ISO 6888-2) and in water testing controls (NF T90-412).
H2B also offers other RPF components separately such as Rabbit Plasma and Soybean Trypsin Inhibitor.
Rabbit Plasma shows excellent specificity towards staphylococcal coagulase and great aptitude to rapidly produce clot formation. Rabbit plasma is reinforced with Bovine Fibrinogen. Soybean Trypsin Inhibitor is needed to prevent fibrinolysis.
H2B Bovine Fibrinogen is offered in powder or in 5% frozen solution, ready-to-use. Liquid form enables to save the time and cost of solubilisation and filtration. Bovine Fibrinogen in 5% frozen solution can be sold alone or with the addition of Soybean Trypsin Inhibitor.
