Rainbow Trout Serum

Rainbow Trout Serum is a specialized biological product derived from the blood of rainbow trout (Oncorhynchus mykiss), often used in cell culture applications, particularly for research in aquaculture, fish biology, and immunology. It is considered a suitable alternative to mammalian sera like fetal bovine serum (FBS) in situations where fish cells or aquatic models are being studied.

This serum is phylogenetically distinct from mammalian sources, reducing the risk of cross-species reactivity, making it ideal for research requiring fish-specific proteins or for studies where mammalian sera may interfere with experimental outcomes. Rainbow Trout Serum is commonly used in applications such as cell-based assays, nutrition and metabolism research, and aquaculture health management, where the need for non-mammalian serum is crucial. It is also employed in blocking buffers and as a replacement for FBS in certain cell cultures.

The serum is carefully processed to retain key proteins essential for cell growth. Its use is increasingly recognized in the field of cultured meat production and in studies focused on fish disease diagnostics and research.

Researchers working on fish cell line development, serum-based immunoassays, and aquatic toxicology often rely on Rainbow Trout Serum for its species-specific protein profile and low cross-reactivity with mammalian antibodies. It supports optimal growth conditions for primary and immortalized rainbow trout-derived cells, making it highly valuable in pathogen-host interaction studies, vaccine efficacy testing, and immune response modulation in teleost fish.

The use of Oncorhynchus mykiss serum is also gaining momentum in biocompatibility assays for aquaculture therapeutics and in the production of serum-supplemented media for cold-water species. Its compatibility with various downstream applications—including Western blotting, flow cytometry, and ELISA development—makes it a versatile reagent in comparative immunology and marine biotechnology workflows.
