摘要:
The invention concerns calibrators or calibration solutions which are based on a human serum matrix and which are used in a method for detecting cytokeratin, a process for producing them, a method for stabilizing cytokeratin and an immunological method for detecting cytokeratin in a sample.
摘要:
The invention concerns an immunological process for the detection of an analyte in a sample, in particular of tumor markers wherein for the reduction of interference substances containing a peptide sequence derived from the framework regions of the variable domain of the antibodies to be detected or the antibodies used for immune therapy or scintigraphy are added to the test preparation. Furthermore, the invention concerns the use of such substances for the reduction of interference of immunoassays, a suppressive agent and a process for the reduction of interference of immunoassays by the substances mentioned.
