Profile: Southern Cross Biotechnologies (NZ) Ltd. produces animal sera from the best bred pasture-grazed cattle. Our products include adult bovine serum, defibrinated adult bovine serum, new born calf serum, fetal calf serum, adult bovine plasma, bovine albumin, and bovine hemoglobin. All the animals are subjected to ante-mortem and post-mortem examinations by qualified and registered veterinarians. Blood is collected from animals which are fit for human consumption. Immediately after slaughter, whole blood is collected, clotted or defibrinated (depending on client requirements), centrifuged and frozen. Frozen serum is sent to the laboratory for filtration and sterilization. Finally, serum is stored in 4.5/20 L HDPE containers at -20 °C. Low endotoxin bovine albumin is ideal for sensitive cell and tissue culture.
