Bovine serum albumin (BSA or Fraction V) is a blood-derived globular protein sourced from fetal bovines. BSA is a component of fetal bovine serum and is considered to be a universal blocking reagent; it is the most commonly used biologic in life science applications because of its stability and and lack of interference with other biologicals. The most common applications are:
Biologos offers general and customized bovine serum albumin.
Our quality control testing, tests for microbiological abnormalities, such as the presence of bacterial, fungal, and mycoplasma contamination and viruses. Fetal Bovine Serum is also tested for adventitious agents using modified procedures from the Code of Federal Regulations, Title 9, Section 113.53 (“Requirements for Ingredients of Animal Origin”). Once the absence of contamination has been confirmed and approved, lots of serum are prepared for the packaging and distribution process.
This process begins with the serum being thawed under controlled conditions and sterile filtered. Sterile filtration involves the serums being filtered through a series of filters in descending pore size, utilizing 0.2 micron filters for the final filtration step. Filling takes place in a laminar flow hood and a certified clean room to maintain ISO Class 5 (FED STD 209E equivalent Class 100) cleanroom conditions . The Fetal Bovine Serum is aseptically dispensed into gamma irradiated, sterile PETG or HDPE bottles and LDPE bioprocess bags (20-100 liter capacity). Filled containers are then labeled, frozen, and maintained at temperatures less than -5°C to preserve the product quality.
Each batch of serum meets the USDA standards for animal products, Biologos’ standard for raw materials, is traceable to date and collection location, and are processed using:
Biologos’ serums are trusted and have been used in the advancements of animal health and diagnostic labs globally for more than 40 years.
Bovine Serum is shipped frozen by truck or next day air in insulated containers packed with dry ice.
Bovine Serum can be supplied in gamma irradiated, sterile PETG or HDPE bottles and LDPE bioprocess bags (20-100 liter capacity). We recommend that the Bovine Serum be stored frozen at a temperature of -5°C to -20°C. Multiple freeze-thaw cycles of the Bovine Serum should be avoided as this may lead to deterioration of the product. Always use aseptic techniques when handling the serum and aliquot into sterile containers.
Bovine Serum Albumin has several industry applications in the fields of Immunology, Biochemistry, and Biotechnology, the most common applications are:
BSA is most commonly used to stabilize enzymes and in the Bradford Protein Assay.
