Bovine Fetuin

Fetuin is a mixture of proteins and other compounds containing a wide range of growth and attachment factors normally found in foetal calf serum. The major protein components include α-1-glycoprotein with a molecular weight of 48.4kD. It is composed of approximately 74% protein with a carbohydrate moiety (sialic acid) attached. Other components in Fetuin include α-1 and α-2 globulins, ß-globulins and a variety of growth factors such as IGFs and FGFs.


Fetuin is a potent serine protease, trypsin-like inhibitor, with mitogenic capability and therefore an ability to facilitate cell attachment by inhibition of proteolytic activity. Fetuin enhances the growth of cells beyond the capacity of insulin, transferrin and selenium and therefore provides the benefits of foetal serum without actual serum supplementation.


Bovogen Biologicals’ Bovine Fetuin is produced from extensively tested serum where low bacterial and low haemoglobin contamination is required for it application.


Bovogen Biologicals’ Fetuin is manufactured using a proprietary modified Peterson fractionation method.
