  • Processes and agents for detecting Listerias
    Patent number: 6951925
    Abstract: The invention relates to agents and processes for detecting bacteria of the genus Listeria, in particular L. monocytogenes. The agents according to the invention include primers whose sequence is selected from the iap gene of L. monocytogenes. In addition, the agents according to the invention include peptides whose sequence is selected from the p60 protein and which are suitable for producing specific antibodies for the immunological detection of L. monocytogenes.

  • Method of detecting protein and a kit using the same
    Patent number: 6703243
    Abstract: A method for detecting protein present on the surface of a sample is disclosed, wherein substances present on a portion of said surface are transferred to a sampling means and wherein, subsequently, these substances are contacted with a reagent capable of forming or changing color upon reaction with protein. Finally, the color changed or formed by this reaction is visually determined. In this method, the substances transferred onto the sampling means are also contacted with a specific type of nonionic or zwitterionic surfactant.

  • Compositions and procedures for the determination of hydrolytic enzymes
    Patent number: 6004769
    Abstract: The invention relates to compositions and procedures for the determination of hydrolytic enzymes in liquid samples with the aid of indoxyl compounds and oxidizing agents. The procedure is characterized in that the absorbent carrier impregnated with an indoxyl compound is wetted with the sample solution, immersed in the solution comprising the oxidizing agent, incubated and analysed by reflectometry.
