Donor Bovine Serum, Heat Inactivated

Donor Bovine Serum, Heat Inactivated Summary

Why Use Donor Bovine Serum, Heat Inactivated?

Donor Bovine Serum is collected from healthy, live animals greater 12 months of age or older.  The donor cattle are carefully selected and maintained in closed herds ensuring complete control of their care, diet and health. Before acceptance into the segregated herd, all cattle must test sero-negative to Infectious Bovine Rhinotracheitis (IBR) and Bovine Viral Diarrhea (BVD). The animals are used exclusively for the production of donor bovine products such as bovine serum and are not medicated or fed sub-therapeutic levels of antibiotics.

Serum products should be stored and handled correctly to assure long-term stability and to preserve growth performance consistency throughout its shelf-life. In addition, heat inactivation of serum is frequently desired to inactivate complement within the serum. Below are protocol links for serum storage/handling and heat inactivation.

Why Heat Inactivate Serum?

The objective of heat inactivation is to destroy complement activity in the serum without affecting the growth-promoting characteristics of the product. Removal of complement activity from the serum is not required for most cell cultures, but may be necessary for cultures that are sensitive to the complement activity. Since heat inactivation of the serum may, to some extent, decrease the growth performance properties of the serum, this procedure should only be performed if actually required for optimal cell growth. Researchers should evaluate the applicability of heat inactivation in regards to their own application. If heat inactivation is required, the process should be carefully controlled to avoid increased formation of crystalline and flocculent precipitates, gelling of serum proteins and excessive loss of growth performance. Significant damage to serum can occur when it is subjected to higher than required temperatures or heated over extended lengths of time.
