摘要:
A peptide according to the present invention is not more than 40 amino acids long and contains a sequence which is at least 6 amino acids long from the amino acid partial sequence between the amino acids 144 and 183 of human .alpha.1-microglobulin or/and a sequence which is at least 6 amino acids long from the amino acid partial sequence between the amino acids 1 and 20 of human .alpha.1-microglobulin.An antibody according to the present invention is capable of specific binding to a peptide according to the present invention as well as to human .alpha.1-microglobulin.In order to determine human .alpha.1-microglobulin in a sample liquid by an immunoassay, the sample liquid is brought into contact simultaneously or sequentially with defined amounts of the components antibody and peptide whereby one of the components is labelled and the determination is carried out by means of this label.

摘要:
Method and device for processing nucleic acids in a reaction mixture on a surface that can be temperature-controlled and its immediate vicinity wherein the main space of the reaction mixture remains essentially isothermal. The method has the advantage of a very short processing time.
摘要:
The invention involves methods and kits useful in determining specific mRNA molecules. The methods can be carried in a single reaction vessel, in that both reverse transcriptase and amplification can be carried out in the same, heat stable reaction vessel.
摘要:
Device for the isolation of nucleic acids from a liquid sample by introducing the liquid into the device through an inlet opening and passage of the sample through a nucleic acid binding material and discharging of the resulting liquid through an outlet opening, wherein the nucleic acid binding material is inserted through the outlet opening during the manufacture of the device and the outlet opening is narrowed in order to hold the material. The device is particularly simple and reliable to manufacture but yet ensures that nucleic acids can be isolated without contamination.

The invention concerns interference-eliminating agents for avoiding unspecific interactions in immunoassays in which avidin or streptavidin or a derivative thereof are used as the interference-eliminating agents.
摘要:
The invention concerns a method for the simultaneous colorimetric and electrochemical measurement of an analyte using an oxidizing enzyme and a chromogen A that accepts electrons from the enzyme which is characterized in that the chromogen A after reduction to A' reacts by coupling to a substance BX to form a colored substance A'B the concentratin of which is measured colorimetrically as a measure for the presence or amount of the analyte and in that an electrochemically measurable group X.sup.- is cleaved off during the coupling reaction the concentration of which is measured electrochemically as a measure for the amount of the analyte.
