  • Instrument for taking a tissue sample
    Patent number: 9050071
    Abstract: An instrument for taking a tissue sample includes a tissue receiving element with a distal end and a proximal end and at least partly has a spiral or helix that has an outer surface and a central longitudinal axis (X-X?). The spiral or helix has at least has one zone where the distance (dd) from the outer surface to the central longitudinal axis (X-X?) is smaller than at a more proximally located part of the spiral or helix.
    Type: Grant

  • Capillary electrophoresis method using initialized capillary and polyanion-containing buffer and chemical kit therefor
    Patent number: 5611903
    Abstract: A capillary electrophoresis detection and/or analysis method comprising the following steps:rinsing a ready-to-use capillary with an initiator to create an initialized capillary,adding a capillary buffer into the initialized capillary,injecting a sample to be analyzed (possibly diluted with a sample diluent) into the initialized capillary,optionally, adding a cathodic buffer to the cathodic end of the capillary, andsubmitting the sample to capillary electrophoresis.In this method, the capillary and/or cathodic buffer comprise(s) a polyanion or a mixture of polyanions. The polyanion or the mixture of polyanions is included at least in the capillary or the cathodic buffer. The method can additionally comprise rinsing the capillary with NaOH after electrophoresis.The present invention also includes a capillary electrophoresis detection and/or analysis unit, including an initiator and a capillary buffer and/or a cathodic buffer.

  • Method for the separation of glycosylated hemoglobin Hb A1c by agarose gel electrophoresis
    Patent number: 5246558
    Abstract: According to the invention, an agarose gel containing chondroitin sulfate is used as a support medium for electrophoresis for separating glycosylated hemoglobin Hb Alc from the other types of hemoglobins.A densitometric analysis of the gel after electrophoresis enables the percentage of each type of hemoglobin contained in the sample to be quantified.
