Why Does Material Precipitate In FBS Upon Storage In The Refrigerator?


Written by admin on February 20, 2013. Posted in FAQs

FBS is not pre-aged. When stored at 2 to 8C, the possibility exists for various proteins and lipoproteins in serum (e.g., cold agglutinins, fibrinogen, vitronectin, etc.) to aggregate, and form either perceptible material or observed turbidity. This should not affect serum performance. We recommend that you store FBS at -20C and avoid repeated freeze-thaw cycles.
