Fetal Bovine Serum, Brazil, Tetracycline Free, 500 ml

Tetracycline-free fetal bovine serum (FBS) is a specialized type of FBS that has been rigorously tested to ensure the absence of detectable tetracycline and its analogs. This is crucial for experiments that rely on tetracycline-inducible gene expression systems, where even trace amounts of tetracycline can lead to unintended gene expressions.

Key characteristics of tetracycline-free FBS include:

• Absence of tetracycline: Ensures no interference with tetracycline-inducible systems.
  
• Consistency: Manufactured to provide uniform performance across different batches.
  
• High quality: Undergoes functional, cell-based assays to verify the absence of tetracycline.
  

Applications of tetracycline-free FBS include:

• Gene expression studies: Ensures precise control over gene expression in Tet-On and Tet-Off systems.
  
• Drug screening: Facilitates accurate testing of drug effects on gene expression.
  
• Vaccine development: Used in the production of safer vaccines with controlled gene expression.
  
• Cancer research: Supports studies on gene regulation in cancer cells.
  

This type of serum is particularly useful in experiments where the presence of tetracycline could interfere with the results, allowing for more precise and reliable outcome.
