    摘要: A method of sterilising a protein, comprises exposing to ionising radiation an at least substantially dry composition comprises a protein and a protective compound or combination of protective compounds having both of the following characteristics: (i) a rate of reaction with singlet oxygen greater than 1 x 10 7 L mol -1 S -1; (ii) being a reducing agent whilst at the same time containing a proton dissociable group with a pKa no more than 3 units from the pH of the composition. The compound having characteristic (i) is selected from histidine, thiamine and tryptophan, the compound having characteristic (ii) is selected from methionine, malate, citrate, lactate and tiron. The radiation is gamma radiation or electron beam, whereby the preferred dose is 15 - 40 kGy.

    摘要: A skin dressing is provided comprising a first component comprising a source of protons, a second component comprising a nitrite salt, the dressing comprising a non- thiol reductant, such that, when the first and second components are brought together and applied to a skin site the nitrite reacts to generate nitric oxide, increasing the pH of the dressing in contact with the skin from an acidic value to a more neutral value.
