//Blood Red
  • An enriched general purpose broth enriched with 10% defibrinated horse blood for the isolation of fastidious organisms.

  • It is not possible to sterilise whole blood products and therefore they must be collected aseptically. Horse and sheep blood are the most widely used animal blood products in culture media. The choice of  which type of blood to use with culture media is largely traditional, with much of continental Europe preferring sheep blood, whilst the UK and certain parts of the Commonwealth  prefer horse blood. Defibrinated horse blood is aseptically collected whole horse blood that has been processed to remove fibrin. There are no additives or preservatives in this product. Defibrination is now accepted as the best method of preventing blood clotting. It must be carried out immediately after drawing the blood and the agitation must be sufficient to denature the fibrinogen but not to cause rupture of the erythrocytes and haemolysis. The haemolytic reactions of horse blood are not identical to sheep blood and blood agar media designed for horse blood may not be satisfactory with sheep blood and vice versa.

  • It is not possible to sterilise whole blood products and therefore they must be collected aseptically. The sodium citrate solution that is added to the sheep blood is manufactured from a salt through the reaction of sodium carbonate with citric acid and this solution serves as an anticoagulant and helps to preserve the blood. The Sheep Blood Citrate (SBC) is aseptically collected and prepared to order from our colony of animals. Sheep Blood Citrate is ideal for blood agar plate preparations. Blood Agar is a general purpose enriched medium often used to grow fastidious organisms and to differentiate bacteria based on their haemolytic properties. Citrated Sheep RBCs are also useful for the titration of Complement, adsorption procedures, testing for agglutinins/HA assays, and for other serological testing.

  • This product is primarily used as a fixation agent in immunological complement fixation assays. The Sodium citrate acts as an anticoagulant in the Alsever’s solution once it is combined with the sheep blood.
