BLOOD PLATELET LYSATE, METHOD OF ITS PREPARATION AND A CELL CULTURE MEDIUM CONTAINING SAID BLOOD PLATELET LYSATE

摘要

The present invention relates to a blood platelet lysate which has been obtained from plasma from animal whole blood. The invention also relates to a method for preparing said platelet lysate and a cell culture medium containing the same. The platelet fraction is separated from plasma and concentrated, whereupon the platelets are caused to lyse. The obtained lysate of platelets can be used to wholly or partly replace foetal calf serum in cell culture, such as in culture of hybridoma cells for preparing monoclonal antibodies.
