  • Patent number: 11598772
    Abstract: A diagnostically useful carrier includes a means for specifically capturing an antibody to a polypeptide from the group including squid MLC1 or squid MLC2 or a variant thereof in a sample from a subject. A method includes the step detecting in a sample from a subject the presence or absence of an antibody to squid MLC1 or squid MLC2. The polypeptide or the carrier or a polypeptide binding specifically to an IgE antibody from the sample of a patient to squid MLC1 or squid MLC2 are useful for the manufacture of a diagnostic kit, preferably for the diagnosis of allergy.

  • Patent number: 11504718
    Abstract: An elongated incubation trough has an indentation open toward a top end as well as a bottom. The indentation has a first receiving area to receive an elongated test strip as well as a second receiving area to receive an end section of a fluid line. The second receiving area is in fluidic communication with the first receiving area. A maximum width of the second receiving area at bottom height is greater than a maximum width of the first receiving area at bottom height.

  • Patent number: 11119109
    Abstract: The present invention relates to a method for diagnosing an allergy, comprising the steps of bringing into contact of basophils from a whole blood sample of a patient with an allergen in an aqueous solution in the presence of whole blood, with a volume content of whole blood in the aqueous solution of at least 20 percent by volume, under conditions that allow activation of the basophils by the allergen, enrichment of the basophils from step a) and detection of activated basophils, wherein the detection is carried out in that the expression of a marker characteristic of activated basophils is detected by means of chemiluminescence; and a kit comprising a vessel for bringing the basophils into contact with the allergen, wherein the vessel is preferably a microtiter plate, optionally an allergen, an agent for detecting a marker characteristic of activated basophils by means of chemiluminescence, wherein the agent is preferably a ligand against the marker provided with a label capable of chemiluminescence and the

  • Publication number: 20200398269
    Abstract: A sample support has an absorbent membrane layer which is based on a nonwoven polyolefin and which has at least one take-up region with dried blood constituents. It moreover has a film layer based on a plastic, where the film layer has received antistatic pretreatment. The membrane layer and the film layer have been connected to one another mechanically in one subregion of the sample support. but the layers have moreover not been connected to one another mechanically in the take-up region. It is preferable that, when the sample support is placed onto a uniformly level surface the membrane layer covers the film layer at least in the take-up region.

  • Patent number: 10871493
    Abstract: A diagnostically useful carrier has a polypeptide for specifically capturing an antibody to Ara h 7 isotype 7.0201 in a sample from a subject. A method includes detecting in a sample from a subject the presence or absence of an antibody to Ara h 7 isotype 7.0201. A pharmaceutical composition includes Ara h 7 isotype 7.0201 or a variant thereof.

  • Publication number: 20200341005
    Abstract: A carrier includes at least one take-up region based on a non-woven polyolefin containing dried-up capillary blood. The carrier is useful for semi-quantitatively, preferably quantitatively determining the concentration of an analyte in a blood sample. Further, a method is used for detecting an analyte in a blood sample and includes the steps of providing the carrier, applying a blood sample to the take-up region of the carrier, drying the carrier, contacting the carrier containing the dried-up capillary blood with a liquid which is suitable for taking up the analyte from the dried-up blood sample, and detecting the analyte in the liquid.
