  • Method for isolating urea while removing objectionable CO2
    Patent number: 10266872
    Abstract: A method for isolating urea and removing CO2 from plasma samples, comprising the following steps: a) providing a plasma sample; b) adding an acid so as to partially remove CO2; c) lyophilizing the sample so as to further remove CO2 and obtain a dried sample; and d) redissolving the dried sample and neutralizing to a pH value of 4 to 7 using a buffer solution, wherein optionally a filtration step is carried out before adding the acid.

  • Process for the preparation of disinfected human cell suspensions
    Patent number: 10017742
    Abstract: In a process for preparing disinfected preparations from mammalian tissues, mammalian tissue is perfused at one step with an enzyme-free liquid antibiotic composition that includes at least one antibiotic and is contained in at least one perfusion buffer. In a step occurring after such one step, enzymatic antibiotic-free treatment of the tissue is carried out to obtain a single-cell suspension. In another step disinfected preparations are obtained.
