Endotoxin (LPS) is known to induce systemic and neuroinflammatory responses in animals, which can complicate experimental results and potentially invalidate pre-clinical data. Also, recombinant proteins contaminated with endotoxins may adversely affect cellular behaviour due to their immunostimulatory and cytotoxic properties.
Sino Biological's Center for Bioprocessing (C4B) in Texas produces ProPure™ endotoxin-free proteins with levels below the quantification limit (BQL) (< 0.05 EU/mg), which exceed the industry standard (0.5 EU/mg according to USP <85>), best for pre-clinical animal studies, accurate cell assays, and detection assays.
