Optimal Supplements for Serum‑Free Culture Media in Large‑Scale Production of Recombinant Protein Raw Materials
To ensure cells achieve optimal health status, proliferation rate and functional performance during cultivation, abundant nutrients, antioxidants, signaling and transport proteins, hormones, cytokines and other components must be supplemented into the culture system. These elements are all indispensable constituents of the extracellular microenvironment in native tissues.
Although bovine serum albumin (BSA) and fetal bovine serum (FBS), as readily available and widely used nutrient sources, can satisfactorily meet these complex demands, their inherent non‑chemically defined characteristics lead to batch‑to‑batch performance inconsistency and increased variability of experimental results. Furthermore, these materials harbor latent risks of sporadic pathogen contamination, threatening the safety and purity of cell culture.
Accordingly, the use of serum‑free media or chemically defined media is critical for highly sensitive experimental research, as well as strictly regulated industrial and clinical applications. By precisely controlling chemical compositions, these media avoid variability derived from natural sources and potential biosafety risks, providing a more stable, reliable and pure environment for cell culture, thereby ensuring the accuracy and reproducibility of experimental outcomes.
Beijing Anrate Biotechnology Co., Ltd. provides a portfolio of large‑scale manufactured recombinant protein raw materials. All products are produced using animal‑free host‑based recombinant technology to ensure high purity and batch‑to‑batch consistency. Free of animal‑derived serum, these products effectively reduce or eliminate serum, serum proteins and related contaminants in cell culture media.
Product Advantages
- Animal‑Free: Free from animal‑derived contamination
- Reliable: Consistent product quality and stable supply; unlimited single‑batch production available
- Top‑Tier Quality: Premium‑grade performance with ultra‑high purity
Recombinant Human Serum Albumin
Anrate Recombinant Human Albumin is produced via a recombinant Pichia pastoris fermentation process, featuring ultra‑high purity, large‑scale production capacity, and excellent batch‑to‑batch consistency. Free from serum and animal‑derived components, this product can directly replace human serum albumin (HSA) and bovine serum albumin (BSA) while effectively reducing the usage of fetal bovine serum (FBS) in cell culture media. It provides essential nutritional support for cells and promotes healthy growth.
Recombinant Human Transferrin
Anrate Recombinant Human Transferrin (rHTf) is produced via a recombinant Pichia pastoris fermentation process, featuring ultra‑high purity, large‑scale production capacity, and excellent batch‑to‑batch consistency. Free from serum and any animal‑derived components, this product can directly replace bovine transferrin (bTF) while effectively mitigating the risk of animal‑derived contamination. As a key iron transport protein, rHTf is responsible for the chelation and transport of iron ions, promoting the recycling of iron in cell culture media, reducing the generation of harmful reactive oxygen species (ROS), ensuring cells obtain essential iron elements, and supporting their healthy growth.
