  • Patent number: 6635222
    Abstract: A method for sterilizing products to inactivate biological contaminants such as viruses, bacteria, yeasts, molds, mycoplasmas and parasites is disclosed. The method involves irradiating the product at a low dose rate from about 0.1 kGy/hr. to about 3.0 kGy/hr. for a period of time sufficient to sterilize the product. The method does not destroy sensitive materials such as blood and blood components. Further, the method does not require pre-treatment of the product such as freezing, filtration or the addition of chemical sensitizers.

  • Patent number: 6193891
    Abstract: The present invention pertains to improved methods for the selective separation of organic components from biological fluids. More particularly, the present invention pertains to methods for the selective separation of organic components from biological fluids which comprise the step of contacting the biological fluid with a synthetic hydrated alkaline earth silicate (i.e., SHAES), such as synthetic hydrated calcium silicate (i.e., SHCS) or synthetic hydrated magnesium silicate (i.e., SHMS). In a preferred embodiment, the present invention pertains to such methods where the biological fluid is a mammalian blood fluid (e.g., whole blood, blood plasma, blood serum, blood fraction, plasma fraction, serum fraction).

  • Patent number: 5362442
    Abstract: A method for sterilizing products to remove biological contaminants such as viruses, bacteria, yeasts, molds, mycoplasmas and parasites is disclosed. The method involves providing the product in a form that contains less than 20% solids and subsequently irradiating the product with gamma irradiation over an extended period of time. Generally the product is irradiated for a period of not less than 10 hours. The extended irradiation time in conjunction with the low level of solids in the product substantially reduces the damage to the product. The method is useful in sterilizing sensitive materials such as blood and blood components.
