Human Serum & Plasma
Blood is comprised of several factors, mainly plasma, serum, white blood cells for immune response and red blood cells for oxygen transport. The most notable difference between serum and plasma lies in the presence of clotting factors, blood serum is mostly water containing dissolved hormones, proteins, carbon dioxide and minerals, it contains 6-8% of the proteins found in blood but does not contain the main blood clotting agent, fibrinogen. Plasma is a yellowish, clear liquid mainly composed of water which makes up 50-60% of the bloods volume. Blood plasma contains fibrinogen and other blood clotting factors not found in plasma. Serum and plasma are usually produced by separating donated blood through centrifugation. Many cell cultures involving the use of human cell lines as well as diagnostic applications such as immunohistochemical staining, antigen typing etc will not function efficiently in the presence of commonly used animal serum media such as foetal bovine serum. Many of these applications require the addition of human serum to the culture medium.
