Heat inactivation is required based on the specific application or protocol. It is typically necessary for hybridoma cultures or immunological studies that require the inactivation of complement proteins. However, heat inactivation is not required for all applications.

How to heat inactivate this serum Fetal Bovine Serum USA origin,(Cat Log - F2442)
1 answer-
Heat inactivation occurs when serum is heated to 56°C for a period of 30 minutes.
Here's a protocol for heat inactivation:
1. Allow serum containers to come to room temperature. Swirl bottles of serum immediately before adding to the water bath.
2. A water-filled control bottles (T1) should be placed in a 56 °C water bath. Place the containers in the water bath up to the serum line. Do not completely submerge the containers. When the temperature of T1 reaches 56 °C, start the timer set for 30 minutes. Do not allow temperatures to exceed 56 °C. Higher temperatures will denature the proteins, gel the serum or alter the performance of the serum.
3. Gently swirl the bottles every 5 to 10 minutes while in the water bath and check the temperature in the control bottle. It is not uncommon for plastic containers to bow slightly after heat treatment. This is not harmful to the serum.
4. At the end of 30 minutes remove the serum bottles from the water bath. Aliquot the serum into smaller volumes and freeze. Sigma-Aldrich does not recommend repeated thaw-freeze cycles.Helpful?

can F2442 FBS be used for culturing peritoneal macrophages? what is the suitable one?
1 answer-
This product is tested for suitability in mammalian cell culture. While it is not specifically tested on macrophages, it is subject to stringent specifications, including low endotoxin, and should perform well. Please see the link below to review a sample Certificate of Analysis:

Does Sigma-Aldrich offer fetal bovine serum (FBS) that is antibiotic-free?
1 answer-
FBS can be tested for the presence of antibiotics. Products F2442, F0926, and F6178, Fetal Bovine Serum are routinely tested for Tetracycline (by far the most commonly used antibiotic in animals) and the results are reported on the lot specific Certificate of Analysis.Per the USDA, Antibiotics may be given to prevent or treat disease in cattle. A "withdrawal" period is required from the time antibiotics are administered until it is legal to slaughter the animal. This is so residues can exit the animal's system. FSIS randomly samples cattle at slaughter and tests for residues. Data from this Monitoring Plan have shown a very low percentage of residue violations.The USDA does random sampling of all cattle submitted for slaughter in USDA inspected facilities for antibiotics. The mandatory withdrawal period is 24 hours. Based on withdrawal periods required by the USDA, animal testing at slaughter and finished product testing, our serum is antibiotic free.

Is Fetal Bovine Serum, Product F2442, available as a charcoal stripped, de-lipidated serum?
1 answer-
We offer Product No. F6765 (Fetal Bovine Serum, charcoal stripped). The charcoal stripping decreases the levels of hormones; it may also decrease the levels of lipids. If further reduction of lipid levels is required, you may need to treat the serum with fumed silica (e.g. Product No. S5130). Use 20 grams of S5130 per Liter of serum (not plasma). It is mixed for 3-4 hours, then centrifuged in 1 L containers for about 15 minutes at 2000 xg. The supernatant can then be decanted, and filtered if desired. NOTE: Silica is extremely fluffy, and care must be taken not to inhale its dust. Allow for about 15% loss of the serum due to adsorption.

Does Sigma-Aldrich offer delipidated bovine serum?
1 answer-
At this time, Sigma-Aldrich does not offer delipidated bovine serum (either FBS or calf serum).A method for lipid depletion, though not necessarily that of Sigma:1. While mixing, gradually add 10 g fumed silica (Product S5130 or Aerosil) per liter of serum2. Mix at room temperature and then transfer to 2-8 °C for overnight mixing.3. After overnight mixing, remove flumed silica (Aerosil) by centrifugation at 3000-5000 rpm for 5 minutes.4. Retain the supernatant. The lipids should stick to the silica. There may be some protein loss
