●Chick Embryo Extract, Ultrafiltrate is used as a supplement in some growth media formulations. It is prepared by blending 11-14 day old chick embryos in a balanced salt solution (3X embryo volume). The solution undergoes centrifugation to remove larger particles and debris. The supernatant is subjected to an ultrafiltration step with a 10kD MW cutoff to remove protein from the solution, producing a clear, amber liquid. This liquid is sterile-filtered.
●Animals are sourced from a specific USDA-Registered facility using a veterinary-inspected flock. Final processing at an ISO9000 facility. Chick Embryo Extract, Ultrafiltrate is protein free. It does not support the growth of viruses.
