Salmon Whole Blood

Antibodies.com supplies whole-blood reagent collected from Atlantic salmon, provided as a liquid suspension in a 50 mL bottle. Because salmon occupies a phylogenetically distant branch from mammals on the vertebrate tree, its blood proteins carry epitopes that rarely cross-react with antibodies raised against mammalian antigens, making the material a useful auxiliary blocking reagent in immunoassays.

Laboratories deploy this preparation in blocking buffers for western blot, ELISA, immunohistochemistry, and flow cytometry workflows, often layered alongside BSA, casein, or commercial fish-serum blockers. It is also used as a heterologous negative control in antibody validation panels, particularly in aquaculture vaccine research, fish immunology studies, and veterinary diagnostics where baseline serum interactions need to be ruled out.

The liquid format ships ready for dilution into assay buffer or for direct application in blocking steps. Storage at refrigerated temperatures is recommended, and aliquoting upon arrival is advised to minimize freeze-thaw exposure and preserve hemolytic activity across multiple experimental sessions.
