The COVID Complex: A Review of Platelet Activation and Immune Complexes in COVID-19

Frontiers in Immunology, 2022
Coronavirus disease 2019 (COVID-19) is a highly prothrombotic viral infection that primarily manifests as an acute respiratory syndrome. However, critically ill COVID-19 patients will often develop venous thromboembolism with associated increases in ...

Radioimmunoprecipitation Assay for Australia Antigen, Antibody, and Antigen-Antibody Complexes

Experimental Biology and Medicine, 1971
SummaryPurified Australia antigen [Au(1)], conjugated with 125I, was reacted with and quantitatively precipitated by human anti-Au(1) in the presence of heterologous antihuman IgG and “dilute” ammonium sulfate. The sensitivity of the devised radioim-munoprecipitation assay procedure proved to be up to 1000 times more sensitive for the detection of ...

Surface Properties of Antigen–Antibody Complexes [PDF]

Scandinavian Journal of Immunology, 1997
In this paper, the authors show that liquid–liquid partition chromatography in an aqueous two‐phase system offers unique possibilities of comparing the overall surface properties of intact antibodies in solution before and after binding of antigen. The authors demonstrate that the surface properties of antigen–antibody complexes are dependent on the ...

The Modified Vaccination Technique

Vaccines, 2018
In addition to active and passive immunizations, there is a third method of immunization, the modified vaccination technique, which is based on injecting a combination of target antigens and antibodies against this antigen.

IgG antibody responses to Plasmodium falciparum merozoite antigens in Kenyan children have a short half-life. [PDF]

, 2007
BACKGROUND: Data suggest that antibody responses to malaria parasites merozoite antigens are generally short-lived and this has implications for serological studies and malaria vaccine designs.

Antibody-Antigen Binding Events: The Effects of Antibody Orientation and Antigen Properties on the Immunoassay Sensitivity [PDF]

, 2023
The sensitivity of an immunoassay depends on a complex combination of the physicochemical characteristics of antigens, antibodies, and reaction surfaces, which are the main elements on which the analytical principle of this technique is based.

Isolation of Circulating Immune Complexes from TB Patient Serum for Serodiagnosis

Bio-Protocol, 2012
Estimation of circulating immune complex in tuberculosis patients has shown better insight to the infection. Isolating circulating immune complex helps quantifying both antigen and antibody in the serum. It’s a simple procedure to improve the sensitivity

The T cell receptor/CD3 complex is composed of at least two autonomous transduction modules [PDF]

, 1992
Recent studies have demonstrated that the CD3-ζ subunit of the T cell antigen receptor (TCR) complex is involved in signal transduction. However, the function of the remaining invariant subunits, CD3-γ, -δ, and , is still poorly understood.

Evaluation of a new system (RAD 120) for the serologic determination of the T.O.R.C.H complex analytes

Microbiologia Medica, 2010
The aim of this study was to evaluate the results of the determination of IgG and IgM against TORCH complex antigens obtained by using a new automatic random-access (RAD 120 – RADIM/SEAC) instrument based on FEIA method, in comparison with the results ...
