Biosera Fetal Bovine Serum (FBS) iFetal Bovine Serum (FBS) is derived from coagulated whole blood, collected from the fetus by cardiac puncture. The blood is immediately centrifuged and the serum is frozen for transfer to our treatment facilities. Upon receipt at the processing plant, the serum is thawed, tested for acceptability, collected and passed through three sterilization filters of 100 nm (0.1 μm). The serum is bottled by an asceptic filling process.s derived from coagulated whole blood, collected from the fetus by cardiac puncture.

Complete Traceability

For all our batches, we have complete traceability. The labeling system is computerized and designed for clarity from batch to batch. Each batch is monitored throughout processing and production to final packaging. The geographical origin is indicated on the Certificate of Analysis which accompanies each delivery of fetal bovine serum.

Quality Control Tests

All sera are rigorously tested for sterility, mycoplasmas, viruses (BVD, IBR and PI3). Each batch is also tested for its ability to withstand cell growth in vitro, plating efficiency and cloning efficiency on the following cell lines: HeLa, L929, SP2 / O-AG14, MRC-5. Certified and specially certified sera are subjected to a battery of additional tests including endotoxin, chemical components, protein electrophoresis and radial immunodiffusion.

BSE

Donors of European origin are tested for BSE before treatment in accordance with European Regulation 999/2001. All animals tested are BSE negative.

原材料的溯源

当科学家选择他们所用的血清时，考虑到的一个重要的因素就是它的来源。因此，血清的可溯源性变得极其的重要。Biosera的胎牛血清来自于心脏穿刺无菌采集胎牛心脏的凝块全血。生产的每批产品，从血清的采集到贯穿整个生产过程的每一步，直至 包装，都严格按照我们的标准进行。所有产品运送到世界各地的顾客手中之前均经过Biosera分析，分类和测试。我们的质量体系可追踪到原材料的供应商和收集血清的屠宰场。Biosera的纵向一体化体系能确保胎牛血清（FBS）真正原产地和可追溯性。

Biosera的质量

用我们的血清对特定的细胞系生长的促进作用来衡量FBS的质量。适用于一种细胞系的血清可能不*适用于另一种细胞系。Biosera的顾客可以先做样品的生长性能的测试再进行购买。有成千上万的不同细胞系，没有两批FBS产品是*相同的，因此我们提供非常宽广的样品和储备政策.

血清的批次留存

在60天的测试期间内，Biosera很高兴为您提供不同批次保存产品的免费试样，一般FBS的试样大小是50ml/批次。如果需要，Biowest可以适当调整以适应客户的要求。试用过后，Biosera可以为没有充足的储存设备的客户保存24个月，在这种情况下，将按计划交货给客户。
