A novel approach to sensitive and rapid antigen detection is described. In the presence of a specific antigen, quantum dot-antibody conjugates rapidly self-assemble into agglomerates that are typically more than 1 order of magnitude larger than their individual components. The size distribution of the agglomerated colloids depends on, among other things, the relative concentration of quantum do...
For earlier diagnosis of human immunodeficiency virus type 1 (HIV-1) infection, the sensitivities of immune complex transfer enzyme immunoassays for HIV-1 p24 antigen and antibody immunoglobulin G (IgG) to HIV-1 p17 antigen were improved approximately 25- and 90-fold, respectively, over those of the previous immunoassays by performing solid-phase immunoreactions with shaking and increasing the ...
conclusions tuberculosis was an important cause of cap in our region. hence, it should be considered in all patients admitted with a cap diagnosis. results among 120 patients with cap, the most common etiology was s. pneumoniae (24.4%), followed by mycobacterium tuberculosis (17.5%), s. aureus (6.7%), polymicrobial agents including anaerobes (4.2%), complicated hydatid cyst (2.5%), influenza a ...
Tuberculosis is the most common infectious diseases. Current diagnostic methods are either slow or lack enough sensivity or specificity. Several mycobacterial antigens are involved in the complex interaction with the immune system of the host. They can be helpful for mycobacteria diagnosis. Antigen 60 (A60) is thermostable antigen found in Mycobacterium bovis and Mycobacterium tuberculosis...
The performance of a norovirus antigen detection assay was assessed using monoclonal antibody NV23 and single-chain antibody HJT-R3-A9 to identify both virus-like particles and virus-containing fecal samples. The detection of 25 different norovirus genotypes as recombinant virus-like particles or in clinical samples was dependent on virus or antigen concentration.
