Based on the high standards and high-quality requirements of the industry and its own management experience, the series of fetal bovine serum products are collected from fetal cattle within 6-8 months of age, and blood is collected by using cardiac puncture technology to avoid pollution. Newborn bovine serum products from Australia or New Zealand are generally collected from newborn bovine blood sources about 7-10 days after birth. All bovine serum products are filtered through 0.1μm grade 3, and the product packaging is made in the original imported PET bottle from Germany, so as to ensure asepsis and no heat source pollution, and the production workshop meets the requirements of cGMP. The production management system and product quality control standards are managed and operated in strict accordance with the international standards of the European pharmacopoeia (EP) and the United States pharmacopoeia (USP).
