Human and animal whole blood, plasma and serum can be supplied as single or a pool of donors.
Human whole blood, human plasma and human serum are drawn from healthy donors. All donors of blood and blood derivatives are tested for HBsAg, HIV1/2 and HCV. Other serological tests can be performed upon request.
All animal biological materials are obtained from licensed facilities. Whole blood is collected from healthy laboratory animals that were maintained under controlled conditions. A health certificate is delivered by a Veterinarian ensuring that the animals were healthy at the collection time.

Processes for blood products
Whole Blood is collected into a sterile blood collection bag or tube containing the anticoagulant for whole blood and plasma or without anticoagulant for serum.
Whole blood can be separated into plasma, serum and globular fractions.
Plasma is the yellow liquid component of blood obtained by centrifugation of whole blood collected with anticoagulant. The most important elements in plasma include proteins (i.e. albumin, globulins and fibrinogen), glucose, clotting factors and hormones.
Serum is the liquid component of blood obtained after blood clotting. The serum is prepared by centrifugation to remove the clot.
Human buffy coat is the fraction derived from a blood sample which contains a mix of platelets and leukocytes (which play a key role in immune reactions). This product is prepared by centrifugation of whole blood.
Globular fractions are the red blood cells whose primary function is to transport oxygen to body tissues via the blood stream. This component is prepared by centrifugation or sedimentation of whole blood to remove the majority of the plasma.
Lipoprotein fractions are plasma proteins, which play a significant role in the transport and metabolism of cholesterol. Lipoprotein fractions include HDL (high density lipoprotein), LDL (low density lipoprotein) and VLDL (very low density lipoprotein).
Use of blood products
To thaw frozen plasma and serum, place the container in a water bath at +37°C and periodically agitate the bottle or the tube during the thawing process to resuspend the viscous solutes and to avoid precipitation. Once the plasma or the serum is thawed, it should be used promptly or divided into single-use aliquots and frozen again.
The thawed plasma and serum may be stored refrigerated at temperatures between +2°C and +8°C for a maximum of one week.
These products are for in-vitro and research use only. They are not intended for any other use.
