Innovative Grade US Origin Fetal Bovine Serum from Innovative Research is collected aseptically from the unborn fetus of adult bovine brought to slaughter. The serum is separated aseptically from the blood of the fetus, which is allowed to spontaneously clot. The serum is collected from USDA-licensed abattoirs located within the US. The animals are inspected pre- and post-slaughter by a licensed veterinarian and are certified free of diseases of clawed animals. The animals used for this material are of US Origin, ensuring that only the highest quality material is used for the production of the serum. The serum is kept under quarantine in a USDA-approved facility until tested and released for sale by the USDA. Material is processed in an FDA-registered facility under cGMP. We offer reliable, consistent products that deliver reliable, consistent results.

Please note – this product replaces our old product number IFBS-PU (same product, new number).

• Preheat a water bath to 37 C.
• Place the frozen plasma sample directly in the water bath.
• Gently agitate the plasma sample every 5-10 minutes to insure even thawing.
• The total thawing time will depend on the frozen sample volume. A 10 ml sample might be thawed completely in 5 minutes, but a large sample could take up to 1 hour.
• The thawed sample should be used immediately or stored at 4 C for up to 24 hours. Liquid plasma should never be kept on ice or stored below 0 C as the cold may cause clotting.
• Plasma should be visually inspected for signs of clotting or precipitation before use in experiments. A coagulation test such as aPTT can also be performed to verify the preservation of the hemostasis system.
• Plasma should always be snap-frozen by placing the tube in dry ice for at least 1 hour. Large containers can be covered in dry ice for even freezing.
• Frozen plasma should be stored at –20 C or colder. Lower temperatures will help preserve labile plasma proteins for longer time periods.
