详细介绍:A cost-effective alternative to Fetal Bovine Serum (FBS). Sourced from New Zealand with complete traceability back to original source. Age of animal at time of collection less than 10 days old. Low in antibodies and high in growth factors. Virus panel testing according to 9 CFR 113.53. Supplemented with iron. All New Zealand calf serum products are carefully collected, processed, and filtered in New Zealand to ensure safety against bovine diseases. We follow the same standards in processing of our calf serum as with our Fetal Bovine Serum (FBS) to enable offering the highest quality and traceability.
