Lampire® Lysed Horse Blood
Defibrinated Blood is manufactured when animal whole blood is aseptically drawn, without the use of an anticoagulant, into a bag or bottle containing marbles to promote clotting. The container is placed on a shaker to ensure the clot aggregates on the marbles. The clot is then removed, effectively eliminating the clotting factors and negating the need for an anticoagulant. A 48 hour microbial content test is performed to screen for gross bacterial contamination, however this test may be waived if a fresher draw is required. Defibrinated blood is sold as a refrigerated liquid, however the following two processing options can be performed in order to keep the product frozen for extended storage: Defibrinated Blood is often used in the manufacturing of Blood Agar Plates, due to the reduced risk of clotting.
Lysed Blood is defibrinated blood which is frozen causing the red blood cells to lyse (rupture), releasing their contents into the serum. Lysed Blood is often used in selective culture media, as some organisms show increased growth in the presence of the red cells’ contents, as opposed to the whole intact cells.
