Sino Biological's ProPure endotoxin-free proteins are produced at the company's Center for Bioprocessing in Texas, achieving endotoxin levels below the quantification limit (< 0.05 EU/mg) - far exceeding the industry standard of 0.5 EU/mg. Some ProPure products even reach 0.01 EU/mg, meeting the demands of sensitive scientific and translational applications where endotoxin contamination can corrupt experimental results and compromise patient safety.

Why it matters

Endotoxins, components of bacterial cell walls, can trigger dangerous hyperinflammatory responses and life-threatening conditions like septic shock. Contamination is a major concern in research, immunology, cell/gene therapy, and vaccine production, where even trace endotoxin levels can skew results and jeopardize safety. Sino Biological's ultra-low endotoxin proteins support accurate experimental outcomes, enhance data reliability, and improve safety for preclinical studies and assays.

The details

Sino Biological's advanced technological processes and equipment allow the company to produce ProPure endotoxin-free proteins with levels as low as 0.01 EU/mg, far exceeding the industry standard of 0.5 EU/mg. The company's rigorous quality control system ensures consistent ultra-low endotoxin levels, providing researchers with reliable assurance.

• Sino Biological's Center for Bioprocessing facility in Texas began producing ProPure endotoxin-free proteins in 2026.
