Precipitates in serum can often appear as large round bodies, even as doublets per microscopic exam. This can be mistaken as a yeast contamination. Brownian motion may be mistaken for motility. These are lipid aggregates that will be readily dissolved when exposed to lipase. Also, these particles will not gram stain or show any growth in culture on aerobic, anaerobic, or fungal media and culture conditions. The performance of the material is not effected. Centrifugation or filtration of small volumes will remove these particles.

This serum is not heat inactivated. If heat inactivated serum is needed, the serum can be heated to 56 °C for 30 minutes. Heating inactivates the complement cascade. Active complement can participate in cytolytic events, leading to contraction of smooth muscle, histamine release from mast cells and platelets, and activation of lymphocytes and macrophages.
Blood is collected and has citrate added as an anticoagulant to inhibit clotting. The blood is then centrifuged and separated into cells and plasma. The plasma is separated from the cells, and calcium is added to the plasma to activate the clotting cascade. The preparation is then centrifuged again, and the serum is the liquid product remaining. This process yields a serum low in growth factors, as it does not contain those factors released from the cells upon clotting.
It is not unusual for our human serum products to be cloudy. This product is from pooled serum and cloudiness indicates that lipids are present in the serum. No clear, lipid-free human serum products are available.
Male blood is used in serum products, where specified, because female serum can have more antibodies resulting from pregnancy. Type AB serum is used as there are no anti-A and/or anti-B antibodies that are found in other blood types.

Product H6914 is prepared from whole blood that is allowed to clot, centrifuged and the serum removed. There is no additional processing required.Product H4522 is prepared from anticoagulated (sodium citrate) whole blood. This is centrifuged to pellet the cells (RBC, WBC, some platelets) and the plasma is removed. This plasma is then treated with calcium to activate the clotting cascade. The preparation is centrifuged again and the supernatant is removed. This product can also be called plasma derived serum.Product H6914 will contain more growth factors since it is allowed to spontaneously clot and there will be the release of growth factors from many of the cells (WBC, platelets) present. The cells are removed before the plasma is clotted for Product H4522, so this plasma will have fewer growth factors present (more similar to what is circulating). Unless testing for growth factors, most researchers are looking for Product H6914.We offer both products heat inactivated.Product H5667 Human Serum Heat Inactivated, from male AB clotted whole bloodProduct H3667 Human Serum Heat Inactivated, from human male AB plasma
