    Abstract: A process for the isolation of a protein from a natural source in sterile form for use as a pharmaceutical product, comprising the steps of: (1) providing a sterilised membrane whose pores are sufficiently small to exclude pathogens; (2) passing a protein solution derived from a natural source through the membrane in a sterile environment; and (3) collecting the sterile filtrate.

    Abstract: The invention provides articles of manufacture and methods for preparing substantially non-immunogenic soft, and bone tissue xenografts for implantation into humans. The xenografts are prepared by removing at least a portion of a soft or bone tissue from a non-human animal to provide a xenograft; washing the xenograft in saline, and alcohol; subjecting the xenograft to cellular disruption treatment; exposing the xenograft to an aldehyde in an amount ranging from about 0.01 % to about 0.10 %; and digesting the xenograft with a glycosidase, and optionally following with a capping treatment. The invention further provides a soft or bone tissue xenograft for implantation into a human including a portion of a soft or bone tissue from a non-human animal, wherein the portion has extracellular components, and substantially only dead cells. The extracellular components have substantially no surface carbohydrate moieties which are susceptible to glycosidase digestion, and have an aldehyde in an amount ranging from about 0.01 % to about 0.10 % of crosslinking the proteins of the extracellular components. Each of the xenografts of the invention are substantially non-immunogenic, and have substantially the same mechanical properties as a corresponding native soft or bone tissue.
