Evaluation of a new immunoassay for chromogranin A measurement on the Kryptor system
BACKGROUND Chromogranin A (CgA) is a biomarker for neuroendocrine tumors (NETs). The aims of this study were to evaluate differences in measurement between the ThermoFisher Brahms CgA Kryptor assay and the CisBio assay and to investigate the influence of patient covariates. Temperature stability of CgA using both assays was determined. DESIGN AND METHODS 406 patients were analyzed for serum C...
متن کاملDEVELOPMENT OF A SIMPLE AND SENSITIVE ENZYME- LINKED IMMUNOSORBENT ASSAY (ELISA) FOR CLINICAL MEASUREMENT OF TESTOSTERONE USING PENICILLINASE AS LABEL
An enzyme-linked immunosorbent assay using a homologous combination of antiserum raised against testosterone-3-0-carboxymethyloxime-bovine serum albumin (T-3-0-CMO-BSA ) and penicillinase-labelled T-3-0-CMO was developed. This assay was utilized to measure testosterone in serum samples of male and female subjects. The sensitivity of the assay is 50pg/well and the antibody developed crossrea...
متن کاملClinical significance of blood chromogranin A measurement in neuroendocrine tumours.
BACKGROUND Tumour marker measurement gives clinicians useful information for the follow-up and management of patients with neuroendocrine tumours (NETs). The currently used tumour markers for NETs are neuron-specific enolase (NSE) and chromogranin A (CgA). The clinical accuracy of these biomarkers depends on histotype and disease extent. CgA is thought to be the optimal marker for most NETs, as...
متن کاملMeasurement of transcobalamin by ELISA.
BACKGROUND Transcobalamin is essential for the cellular internalization of cobalamin. Methods to quantify the unsaturated protein are available, but few attempts have been made to develop methods to quantify the sum of unsaturated and cobalamin saturated transcobalamin. METHODS gamma-Globulins from two polyclonal rabbit antibodies against recombinant human transcobalamin were used as capture ...
متن کاملDesigning an ELISA Method for Measurement of Human IgG and IgM Antibodies against SARS-CoV-2
Background and purpose: Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this study, an indirect ELISA method was designed to measure the human IgM and IgG antibodies against SARS-CoV-2. Materials and methods: Protein sequence of nucleocapsid antigen from SARS-CoV-2 was expressed in E. coli BL21 and then was...
