An immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) was developed by using a 24-amino-acid peptide of the 18-kDa Epstein-Barr virus (EBV) viral capsid antigen (VCAp18). IgM detection was increased by 23% by using this antigen. Detection of IgM antibodies to the EBV proteins in the new ELISA was 100% specific and 95% sensitive.
A new rapid lateral flow fecal antigen detection test for Cryptosporidium was evaluated using diarrheal stool samples from a cohort of children in Bangladesh. The test had a sensitivity of 100% and a specificity of 94% when compared with enzyme-linked immunosorbent assay antigen detection.
A simple and sensitive immunosensor for the detection of cancer biomarker prostate specific antigen (PSA) has been developed. Around the percolation threshold of the graphene film, the conductivity of the graphene film varies significantly with the surface adsorption of molecules, which can be used for the detection of proteins based on antibody-antigen binding.
BACKGROUND AND OBJECTIVES Although parvovirus B19 is a significant blood product contaminant, few methods other than polymerase chain reaction (PCR) have been developed to detect the presence of the virus. MATERIAL AND METHODS A B19 antigen enzyme immunoassay (EIA) has been developed and the sensitivity of detection is ascertained using dilutions of the B19 capsid protein VP2 and 10-fold dilu...
