FBS, AUS Origin, 500mL

Sourced from Australian cattle under veterinary supervision, this 500 mL bottle of Fetal Bovine Serum carries the AUS Origin designation that places it within the negligible BSE-risk category recognized by WOAH/OIE. STEMCELL Technologies sterile-filters the serum through a triple 100 nm pore-size membrane cascade and qualifies each batch against embryonic stem cell proliferation benchmarks, so it supports pluripotent culture workflows rather than only transformed lines.

Researchers add the serum to basal media such as DMEM or RPMI at 5 to 10 percent v/v to deliver growth factors, attachment proteins, hormones, and trace nutrients required for mammalian cell expansion in vitro. Common applications include the maintenance of human embryonic and induced pluripotent stem cell colonies, mesenchymal stromal cell expansion, hybridoma production for antibody generation, fibroblast feeder-layer preparation, and supplementation of viral vaccine production cultures.

For handling, keep the bottle frozen at -20°C or colder until use, thaw overnight at refrigerator temperature without agitation, and protect from light to preserve growth-factor activity. Aliquot into single-use volumes to limit freeze-thaw cycles, then either refreeze or hold the working aliquot refrigerated for short-term use. Each shipment arrives with a lot-specific Certificate of Analysis listing total protein, hemoglobin, osmolality, endotoxin, and virus-screening results, allowing laboratories to match performance data to protocol requirements.
