Fetal 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.

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

當科學家選擇他們所用的血清時，考慮到的一個重要的因素就是它的來源。因此，血清的可溯源性變得極其的重要。Biosera的胎牛血清來自于心臟穿刺無菌采集胎牛心臟的凝塊全血。生產的每批產品，從血清的采集到貫穿整個生產過程的每一步，直至 包裝，都嚴格按照我們的標準進行。所有產品運送到世界各地的顧客手中之前均經過Biosera分析，分類和測試。我們的質量體系可追蹤到原材料的供應商和收集血清的屠宰場。Biosera的縱向一體化體系能確保胎牛血清（FBS）真正原產地和可追溯性。 

Biosera的質量

用我們的血清對特定的細胞系生長的促進作用來衡量FBS的質量。適用于一種細胞系的血清可能不完全適用于另一種細胞系。Biosera的顧客可以先做樣品的生長性能的測試再進行購買。有成千上萬的不同細胞系，沒有兩批FBS產品是完全相同的，因此我們提供非常寬廣的樣品和儲備政策. 

血清的批次留存

在60天的測試期間內，Biosera很高興為您提供不同批次保存產品的免費試樣，一般FBS的試樣大小是50ml/批次。如果需要，Biowest可以適當調整以適應客戶的要求。試用過后，Biosera可以為沒有充足的儲存設備的客戶保存24個月，在這種情況下，將按計劃交貨給客戶。
