What is HyClone FBS?

What is HyClone FBS?

HyClone characterized fetal bovine serum (FBS) is produced using true pool technology, which minimizes bottle-to-bottle variability. This FBS product is filtered through three sequential 100 nm (0.1 µm) pore size-rated filters. Each lot of FBS is subjected to virus panel testing according to 9 CFR 113.53.

What FBS means?

Fetal bovine serum (FBS) is a nutrient-rich cell culture supplement that is high in growth factors and low in antibodies, compared to non-fetal sera.

What is HyClone used for?

HyClone was the first large scale producer to collect fetal bovine blood using a patented closed-system collection method that resulted in serum with exceptionally low levels of endotoxin and hemoglobin.

What does FBS contain?

FBS contains ~100 mg of immunoglobulin per liter, growth factors and hormones, binding and transport proteins, factors for spreading and attachment, aminoacids, vitamins, trace elements, fatty acids, lipids, protease inhibitors.

Why does FBS need to be heat inactivated?

A common treatment of FBS is heat-inactivation, where FBS is heated at 56°C for 30 minutes in a water bath with occasional shaking. The purpose is to inactivate whatever components of the complement system are present in the FBS [24], and other potential unknown inhibitors of cell growth.

What is the normal value of FBS?

A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it’s 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Oral glucose tolerance test.

How can I reduce FBS?

Here are 15 easy ways to lower blood sugar levels naturally:

  1. Exercise regularly.
  2. Manage your carb intake.
  3. Increase your fiber intake.
  4. Drink water and stay hydrated.
  5. Implement portion control.
  6. Choose foods with a low glycemic index.
  7. Manage stress levels.
  8. Monitor your blood sugar levels.

Why is FBS so expensive?

Growing demand, coupled with a lower supply of FBS has resulted in a volatile market for US FBS and consequently prices have increased significantly in the past few years.

How does FBS neutralize trypsin?

FBS contains protease inhibitors particularly α1-antitrypsin, which inhibit the trypsin activity. Even before the addition of trypsin, cells should be washed with PBS to remove any left over FBS, because this could hinder the trypsinisation process.

What happens if you heat inactivate FBS for too long?

The longer you heat inactivate your FBS the more profound such undesired side effects will be. Thus your 2h treated medium could not be perfect any more. 2 hours at 56 °C could destroy the proteins of FBS that are necessary to support the cell growth ( they are cooked). Half an hour at 56 °C is enough.

Why do we use fetal bovine serum?

Fetal bovine serum (FBS) is used as a growth supplement for the in vitro cell culture of eukaryotic cells. FBS contains growth factors and very low levels of antibodies, allowing for versatility in many different cell culture applications.

Is the HyClone premium bovine serum traceable?

For decades, Cytiva’s HyClone premium bovine serum products have exceeded industry standards for quality, purity, and regulatory compliance. HyClone serum processes are traceability-certified by the International Serum Industry Association (ISIA).

How much endotoxin is in HyClone defined FBS?

Our patented closed-system blood collection method and rigorous quality control testing ensure that HyClone defined FBS contains ≤ 10 EU/mL endotoxin and ≤ 10 mg/dL hemoglobin.

Are there any other treatments for HyClone FBS?

Additional treatments are available: HyClone FBS heat inactivated (HI) and HyClone FBS irradiated (IR). Additional testing, including EMEA-conforming testing, is also available.

Where does HyClone characterized fetal bovine serum ( FBS ) originate?

HyClone Characterized Fetal Bovine Serum (FBS), U.S. Origin Enhance cell growth and division using HyClone FBS of U.S. origin, confirmed by ISIA and Oritain.
