For over 30 years, MTF Biologics has been focused on evolving processing technology with aseptic techniques. Aseptic processing ensures preservation of key biological matrices, cell attachment sites, and vital matrix proteins.

Terminal sterilization has been shown to alter tissue structure and matrix properties making cell infiltration and integration more difficult.  The harsh treatment has also been shown to denature matrix proteins that are necessary for cell recruitment and differentiation.1

MTF Biologics requires strict ISO-certified clean rooms and batch/lot testing to confirm sterility assurance levels that conform to USP <71> standards.
