Our Facilities

RMBIO’s state-of-the-art serum and protein fractionation facility located in Missoula, Montana uses proprietary extraction and purification methods based on forty years of proven processes to produce protein fractions and filtered sera. The primary products manufactured in our facility include a complete line of animal sera, including FBS, calf, porcine, and equine serum, as well as serum treatments including low IgG stripping and gamma irradiation. The purpose-built labs are also where we create RMBIO’s proprietary FBS alternative Fetalgro and cell culture supplement Lipogro a bovine cholesterol concentrate; two products that dramatically reduce costs and match or improve FBS’ performance.

All our biomanufacturing systems are designed to ensure product integrity and demonstrate reliability and consistency. Every single product batch is tracked from start to finish under a comprehensive quality system designed to guarantee a consistent, premium end product. This meticulous attention to quality and traceability earned RMBIO an ISIA traceability certification in 2014.
