  • Treating protein-containing liquids
    Patent number: 8226776
    Abstract: Abnormal infective prion proteins are removed from liquids containing biologically active substances, particularly blood products, by filtration using a depth filter formed of a matrix comprising solid particles of porous material and having a pore size less than 6 microns. Preferably the filter is free of cationic or anionic charged material.
    Type: Grant
    Filed: January 19, 2000
    Date of Patent: July 24, 2012
    Assignee: Bio Products Laboratory Limited
    Inventors: Anne Gillian Welch, Peter Reynolds Foster
  • Removal of prion infectivity
    Patent number: 7252720
    Abstract: Prion infectivity adsorbed onto substrates (for example, chromatographic columns used to fractionate blood plasma) is removed by treatment with 2M sodium chloride. Optionally, the substrate is further washed with 0.1 M sodium hydroxide.

  • Uv irradiation control
    Publication number: 20040214335
    Abstract: The present invention relates to methods of monitoring UV-irradiation of and determining, as well as controlling, UV irradiation dosages received by a fluid 16 containing at least one protein, which method comprises the step of monitoring 21 the increase in absorbance which has a peak in the region from 305 to 325 nm, due to said UV-irradiation. The present invention also provides apparatus 1 suitable for use in the methods of the invention.

  • Storage of liquid compositions
    Publication number: 20040199138
    Abstract: Liquid pharmaceutical compositions stored in glass containers, (particularly of blood plasma proteins such as albumin) having a shelf-life in excess of 18 months; over which time the aluminium content is maintained below 200 micrograms per litre. This is achieved by silicone-coating the glass container. Also the particles/ml post-autoclave and post-pasteurisation are kept to low levels.
