Why is there lot-to-lot variability in serum?
Serum products, including fetal bovine serum, contain a complex mixture of biological components, a majority of which have not yet been fully defined. The composition of these serum components naturally varies from lot-to-lot.
The best serum lot for you is the one that works for your cells in your specific application. Strict control of the process from collection through processing enables us to provide a stable, consistent performing, and traceable supply of quality serum throughout global fluctuations in serum availability and regulatory requirements. We can help you select the serum lot that is ideal for your application by offering a variety of programs such as lot matching, extended lot reserves, and free on-site serum storage, geared towards minimizing the impact of serum variability for our customers.
What quality parameters should I consider when sourcing my fetal bovine serum?
When sourcing your fetal bovine serum, the range of quality parameters to consider will be dependent on the cells you culture. As a standard, you can expect the following specifications when considering the quality of R&D Systems™ FBS:
- Endotoxin
- Mycoplasma
- Biochemical profile
- Hemoglobin
- Chemical analysis
- Virus testing
For more demanding or sensitive cell lines, extensive hormone, biochemical and viral testing profiles should be considered. R&D Systems FBS manufacturing processes meet USDA requirements for animal products and ensure the product is traceable back to the date and location of collection.
