Recombinant Rhesus Macaque Amyloid protein A protein (SAA1) (Active)

Serum amyloid A1 is a major acute-phase reactant implicated in monocyte recruitment and amyloid fibril formation, making validated bioactivity essential for meaningful functional studies. This tag-free recombinant rhesus macaque SAA1 (aa 19–122, full-length mature protein) demonstrates confirmed chemotactic activity on human monocytes at 10–100 ng/ml, providing a reliable positive control or stimulus for monocyte migration assays and innate immune signaling experiments. Expression in *E. coli* yields a non-glycosylated protein that eliminates variability from post-translational modifications, supporting reproducible dose-response characterization in cell-based chemotaxis and inflammation studies. Purity exceeding 97% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for functional cell assays, cross-species reactivity comparisons, and preclinical immunology research involving non-human primate models.
