Simple method for preparation of cryoprecipitate (CP) and cryodepleted plasma (CDP). 1984

W Prohaska, and V Kretschmer

Cryoprecipitates (CP) and cryodepleted plasma (CDP) were prepared from fresh frozen plasma (FFP). Plasma was easily and cleanly frozen at -50 degrees C using a methanol-bath Ultracryostat, which has been available commercially for the past few years. From a random sample (n = 6), factors VIII:C, IX:C, V:C, fibrinogen, antithrombin III and fibronectin were determined. Concerning the total contents and the in-vitro-recovery of factor VIII:C (x:104 IU/53.5%) and fibrinogen x:175 mg/36.9%), the preparation method was as efficient as other equally common methods. Apart from the well-known applications, CP may be used for the substitution of fibronectin (x:46.2 mg/73.0%). The supernatant plasma of cryoprecipitation (CDP) can be utilized for substitution of coagulation disorders especially deficiencies of the prothrombincomplex and antithrombin III (x:IX:C:183 IU/76.2%; V:C:140.5 U/73.8%; AT III:162 U/80.2%).

UI	MeSH Term	Description	Entries
D010952	Plasma Substitutes	Any liquid used to replace blood plasma, usually a saline solution, often with serum albumins, dextrans or other preparations. These substances do not enhance the oxygen- carrying capacity of blood, but merely replace the volume. They are also used to treat dehydration.

D011232	Chemical Precipitation	The formation of a solid in a solution as a result of a chemical reaction or the aggregation of soluble substances into complexes large enough to fall out of solution.	Precipitation, Chemical
D005164	Factor IX	Storage-stable blood coagulation factor acting in the intrinsic pathway of blood coagulation. Its activated form, IXa, forms a complex with factor VIII and calcium on platelet factor 3 to activate factor X to Xa. Deficiency of factor IX results in HEMOPHILIA B (Christmas Disease).

D005165	Factor V	Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.

D005169	Factor VIII	Factor VIII of blood coagulation. Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin.

D005340	Fibrinogen	Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.

D005353	Fibronectins	Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.
