Omega Scientific offers a variety of Specialty Treated Fetal Bovine Serum manufactured from the same high quality raw material as their standard FBS, in an ISO 13485 facility. See below for product specifications.
Female Only Fetal Bovine Serum is collected only from female fetuses during cattle harvesting.
Lipid Depleted Fetal Bovine Serum is obtained by using fumed silica precipitation method for removing lipids. The fumed silica powder is mixed into the serum and centrifuged. The lipids attach to the silica in the pellet and the supernatant contains only the serum. After treatment the level of cholesterol is < 10mg/100ml. Lipid Omega Scientific’s Depleted FBS is suitable for lipid-metabolism studies or Arteriosclerosis research. This product is also known as Delipidated FBS
Exosome Depleted Fetal Bovine Serum gives you faster and more accurate results for your research. This product has undergone a proprietary protocol to remove at least 95% of Exosomes that could interfere with your research. The depletion rate is measured by a nanoparticle tracking analysis apparatus (NTA using the NanoSight NS300 apparatus from Malvern).
*TET- System Approved Fetal Bovine Serum is screened for the presence of Tetracycline using a cell-based luciferase reporter system. This FBS has no detectable level of Tetracycline present. Tetracycline is an antibiotic commonly found in Fetal Bovine Serum which can cause problems for researchers using sensitive tet-inducing expression systems.
Charcoal Dextran-Treated Fetal Bovine Serum has lower levels of hormones and steroids. The concentration of these are reduced using charcoal, dextran and NaCl until progesterone concentration is less than 0.2 ng/mL. A hormone panel is performed pre and post-treatment and reported on the COA. Processed serum is thawed and then heated in a water bath at 56°C for 30 minutes. The serum is swirled every 10 minutes to ensure proper integration of concentrated protein.
The heat inactivates the complement in the serum. Complement is defined as a series of 20 proteins produced by the liver which amplify the action of antibodies.
Dialyzed Fetal Bovine Serum is passed through a 0.15M NaCl column to reduce the concentrations of low molecular weight components. The molecular weight cut off used in this process is 10,000.
All FBS is available Heat Inactivated (request if not shown) Processed serum is thawed and then heated in a water bath at 56°C for 30 minutes. The serum is swirled every 10 minutes to ensure proper integration of concentrated protein.
*Replaces TET- Approved Fetal Bovine Serum. SKUs FB-15 and FB-16 were discontinued in 5/2025.
Every lab experiment carries more than just scientific weight. It carries the pressure of deadlines, grant expectations, publication goals, and the simple but critical need for results that can be trusted. Yet all too often, experiments are compromised not because of a flawed hypothesis, but because of something much smaller;
Behind every successful experiment is a series of small, consistent choices and often, the most overlooked are the tools we use every day. In cell culture, even the best protocols and techniques can’t compensate for consumables that fall short on sterility, reliability, or performance. Contamination, variability, and unexpected failures rarely
In the intricate world of cell culture, precision is everything. Monitoring plays a pivotal role in ensuring that cells thrive, experiments succeed, and data remains reliable. However, for many researchers, this critical aspect often becomes a source of frustration. From contamination to data inconsistencies, the challenges of cell culture monitoring
A future where new drugs are developed faster, safer, and with greater precision—without relying on animal testing or lengthy clinical trials. A future where treatments are tailored specifically to your genetic makeup, providing maximum efficacy with minimal side effects. This is the promise of 3D bioprinting in drug discovery, a
Imagine a future where your favourite burger doesn’t come from a farm but a lab—produced without slaughter, with minimal environmental impact, and with the same taste and texture you know and love. This is the promise of cell-based meat cultivation, a revolutionary approach that’s reshaping the way we think about
If you’re working with cell cultures, you already know how critical it is to monitor cell viability and growth at every stage. Whether you’re a PhD student in the middle of a crucial experiment, a seasoned scientist in biotech, or part of a cutting-edge research lab, keeping a close eye
The field of cell culture is evolving at an unprecedented pace, driving breakthroughs across biomedical research, drug discovery, and sustainable bioproducts. From 3D models revolutionizing cancer research to bioreactors scaling up production, the innovations in this space are transforming how we approach science and medicine. In 2022, the global cell
Cryopreservation is an indispensable method that underpins modern biological research and biomanufacturing. By halting biological activity through ultra-low temperature storage, cryopreservation ensures the preservation of cellular integrity, enabling long-term storage without compromising viability or functionality. This process is more than just freezing cells; it is a precise science that demands
At the heart of every successful cell-based experiment lies a simple yet powerful factor: cell culture media. Serving as the lifeblood of cells, it provides essential nutrients, growth factors, and environmental stability, acting as a surrogate microenvironment to replicate physiological conditions. Whether you’re growing mammalian cells for research, hybridomas for
With over 20 years of experience in the life science industry, we work hard to bring our customers the highest quality and most relevant products and services. We specialize in cell culture and diagnostic processed serum, cholesterol concentrates, and purified proteins.
