Fetal Bovine Serum – Premium Select is the highest FBS grade available. It is lowest in endotoxin and hemoglobin, and is suitable even for the most demanding and sensitive cell lines. Premium Select grade FBS is also commonly used when a hormone profile, an extensive biochemical profile and/or an extended virus test panel is required.
Key Benefits:
Highest-grade FBS from R&D Systems
Ideal for sensitive or specialized cell lines
High lot-to-lot consistency
Lowest in endotoxin and hemoglobin levels
Extensive biochemical, hormone, and virus testing
Manufactured from USA-origin or USDA-approved
Manufactured in our ISO 9001:2015 certified facility
Fetal Bovine Serum, also known as Fetal Calf Serum (FCS), is a critical supplement added to cell culture medium to maintain cell health and promote expansion. Different grades of FBS are available from R&D Systems that address the value and premium needs of research.
All lots of Fetal Bovine Serum – Premium Select are sterility, virus, and performance tested, and include a biochemical profile. In addition, a hormone analysis is performed. Lots are manufactured from USA origin or USDA-approved origin material following stringent manufacturing and quality control procedures. All lots of FBS - Premium Select are manufactured in our ISO 9001:2015 certified facility.
Fetal Bovine Serum and other 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.
Collection, Processing, and Testing of R&D Systems FBS
Collection and Processing - R&D Systems FBS is manufactured under a process that meets USDA requirements for animal products and ensures the product is traceable back to the date and location of collection. Our FBS manufacturing adheres to closed-system collection, processing in positive pressure, HEPA-filtered clean rooms, and triple 0.1 um filtration to remove contaminants. 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.
Biochemical Testing - R&D Systems FBS undergo biochemical profiling including total protein, albumin, globulin, IgG, total bilirubin, glucose, iron, cholesterol, triglycerides, sodium and potassium. View the product insert for a complete list of biochemical profiling components, which may vary between grades.
Chemical Analysis - Each lot of FBS is tested for osmolality, pH, hemoglobin, endotoxin (LAL method) and microbiological contamination (using methods recommended by the U.S. Pharmacopeia).
Product Specifications for Fetal Bovine Serum - Premium Select
Scientific Data Examples for Fetal Bovine Serum - Premium Select
Premium Select FBS Performs Consistently Across Lots and Performance Assays.
Quality control data for Premium Select FBS shows high levels of performance consistency. (A) Plating efficiency of cells cultured in media containing 5% or 10% Premium FBS, relative to control lots of FBS. (B) Premium Select FBS is formulated to consistently support hybridoma cloning and is qualified for consistent and healthy expansion of adherent and suspension cell culture lines. In addition to its extended hormonal and biochemical profiling, lots of Premium Select FBS show consistent and high percentage cloning efficiency and cell viability.
Expansion of Human Umbilical Cord Endothelial Cells (HUVECs) using Premium Select FBS.
HUVECs were expanded for 11 passages in media containing Premium Select FBS or an alternate supplier of FBS. (A) HUVEC expansion was consistent over 11 passages and comparable to Supplier #1. (B) Representative images of HUVECs after 9 passages in culture.
