一般描述

胎牛血清（FBS）是一种由低、高分子量生物分子组成的复杂混合物，具有最佳的生长促进和抑制功能。FBS中含有如生长因子、蛋白质、维生素、微量元素、激素等多种分子。这些分子对于细胞的生长和维持至关重要。它是细胞培养基中的一种常见补剂。[1][2]FBS来自于小牛血。它不含有纤维蛋白和凝血因子。FBS的热灭活可阻断补体系统。[3]来源于凝结血的FBS是真核细胞，尤其是哺乳动物细胞培养中最广泛使用的未确定补充剂。[4][5]它通常与在1950年代和1960年代开发的经典培养基一起使用。这些包括多种常用培养基，如Minimum Essential培养基（MEM）、[6]Dulbecco′s改良Eagles培养基（DME，DMEM）、Iscove′s改良Eagles培养基（IMDM）、[7]M199[8]以及Roswell Park Memorial Institute培养基RPMI-1640。[6]

应用

胎牛血清还可作为组分用于：
  • 血管周围巨噬细胞样黑素细胞（PVM/M）生长培养基[9]
  • 合成输卵管液（SOF）[10]
  • Eagle′s minimum essential培养基（EMEM）[11]
  • neurobasal培养基[12]
  • Hyclone McCoys 5 A培养基[13]
  • Hanks培养基[14]

生化/生理作用

FBS仍然是一种常用的培养基补充剂，因为它在细胞培养中提供了广泛的功能。FBS提供营养、生长和附着因子，并通过难以在无血清培养基（SFM）系统中复制的机制保护细胞免受氧化损伤和细胞凋亡。

分析说明

  • 内毒素和血红蛋白测试
  • 检测了是否存在细菌、病毒和支原体
  • 在无菌条件下用0.1微米膜过滤三次

其他说明

Questions

1–10 of 15 Questions  

  1. How to heat inactivate this serum Fetal Bovine Serum USA origin,(Cat Log - F2442)

    1 answer

    1. 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.

  3. can F2442 FBS be used for culturing peritoneal macrophages? what is the suitable one?

    1 answer

    1. 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:

  4. Can this f2442 fbs be used for culture expansion of mesenchymal stem cells? Please confirm Thanks

    1 answer

    1. Fetal Bovine Serum (Cat. no.: F2442) is suitable for use in mammalian cell culture. However, it is not tested specifically in mesenchymal stem cell culture. There is some evidence in the literature that this product would be suitable. See the link below for a relevant reference:
      https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4545441/

  5. How is Fetal Bovine Serum, Product F2442, cell culture tested?

    1 answer

    1. Biological performance is assessed using Sigma cell culture medium supplemented with the serum and tested at a final concentration of 10%. Seeding efficiency, doubling time, and final cell density are measured on appropriate cell lines. Growth studies are carried through two subculture generations and cell growth is plotted as a logarithmic function of time in culture. During the testing period, cultures are examined microscopically for atypical morphology and evidence of cytotoxicity. Hybridoma -tested serum has been shown to support mouse myeloma cells and hybridoma cells in culture.

  6. What is the difference between Fetal Bovine Serum F2442 and 12103C?

    1 answer

    1. Product No. 12103C meets most of the specifications of F2442.  Both products are from the same raw material suppliers and undergo the same stringent testing prior to release. However, the F2442 has been use-tested in hybridoma culture, whereas 12103C has not.

  8. There is a precipitate in my serum.  Is my serum contaminated?

    1 answer

    1. Precipitates in serum can often appear as large round bodies, even as doublets per microscopic exam. This can be mistaken as a yeast contamination. Brownian motion may be mistaken for motility. These are lipid aggregates that will be readily dissolved when exposed to lipase. Also, these particles will not gram stain or show any growth in culture on aerobic, anaerobic, or fungal media and culture conditions. The performance of the material is not effected. Centrifugation or filtration of small volumes will remove these particles.

      Helpful?

  9. Is Fetal Bovine Serum, Product F2442, available as a charcoal stripped, de-lipidated serum?

    1 answer

    1. 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.

      Helpful?

  10. What is the level of growth factors in Fetal Bovine Serum, Product F2442?

    1 answer

    1. Sigma Aldrich does not determine the levels of growth factors (such as TGF beta, VEGF, EGF, PDGF, or FGF) for serum with reduced levels of growth factors and plasma derived serum.
