Depending on your application and cell type, bovine serum alternatives such as newborn calf serum, calf serum or adult bovine serum may be suitable for robust cell lines, short-term culture or specific assay formats. Quimigen also provides sera from other animal species for applications such as immunohistochemistry blocking, veterinary research and autologous culture systems.
Human serum : Human serum can be a relevant alternative for researchers working with sensitive human cells, including macrophages, lymphocytes and other primary human cell types. Human AB serum is particularly useful when a more human-like culture environment is required.
XerumFree™: XerumFree™ is a fully defined, animal-free and human-component-free cell culture supplement designed to replace serum in a wide range of cell culture applications. It helps reduce lot-to-lot variability and avoids undefined serum components that may interfere with experimental outcomes.
UltraGRO™: UltraGRO™ is a xeno-free, animal serum-free human platelet lysate supplement designed to replace FBS for the expansion of mesenchymal stem cells, including bone marrow-, adipose tissue- and umbilical cord-derived MSCs. RUO and GMP-grade options are available depending on your workflow and regulatory requirements.
SEREXISTM : is a defined, homogeneous serum replacement that delivers consistent FBS-like performance across multiple cell lines. Its controlled composition ensures high reproducibility and process control, while enabling direct, seamless substitution for FBS at standard concentrations—no protocol changes required. Combining efficacy, safety, and reliability, SEREXISTM is a versatile, ready-to-use alternative for robust cell culture applications.
