In the chicken, maternal IgG is deposited in the oocyte yolk and subsequently transported intact by the foetal chick yolk sac into the chick circulation. Such transport appears to require a specific membrane-localized IgG receptor. Using the assay of 125I-yolk IgG binding, we have investigated the existence and properties of such receptors in yolk sac tissue disks. We find that: (1) There are s...
Study objective — assessment of the humoral and cell-mediated immunity features in COVID-19 convalescents three months after their discharge from hospital. Material Methods The study involved 78 who, depending on profile specific IgM IgG antibodies to SARS-CoV-2, were divided into groups. control group consisted 50 volunteers. Detection blood serum was performed by ELISA. Determination CRP conc...
Background and Purpose: Aspergillus fumigatus as a ubiquitous fungus can be found in the respiratory tract of the asthmatic and healthy people. The inhalation of Aspergillus spores leads to an immune response in individuals with asthma and results in the aggravation of the clinical symptoms. The present study aimed to investigate the prevalence of specific immunoglobulin E and G (IgE and IgG) a...
background : cytomegalovirus (cmv) is the most common cause of congenital infection, with increased morbidity and mortality at birth. the risk of intrauterine infection largely depends on the time of maternal infection during pregnancy. currently, no national screening test for cmv infection is available during pregnancy in iran. the aim of this study was to determine the seroprevalence of cmv ...
Abstract Background and Objective: One of the proteins shared in all strains of Brucella is 31 kDa surface protein (BCPS31) that could be an appropriate target for immunization and serological diagnosis. Material and Methods: In the present study, BCSP31 produced as a recombinant protein in pET28a (+) expression system was utilized, using ELISA, to detect trace specific antibody (IgG) in brucel...
Background: Immunoglobulins are a group of proteins have important role in defense against microorganisms. Human immunoglobulins are divided into five classes: IgA, IgM, IgD, IgE and IgG. Immunoglobulin G (IgG) is the highest abundant antibody in serum and extravascular fluids. The extent of serum IgG is related to severity of several diseases such as infections, so IgG has great diagnostic wor...
EVALUATION OF SEROPREVALENCE MYCOPLASMA PNEUMONIAE SPECIFIC IGM AND IGG ANTIBODIES IN ASYMPTOMATIC PRESCHOOL-AGED CHILDREN
Background and purpose: Aspergillus is a ubiquitous fungus, which causes a wide spectrum of infections including invasive pulmonary aspergillosis (IPA), depending on the patient’s immune status and underlying lung disease. Among the Aspergillus spp, A. fumigatus remains the predominant agent of IPA. In patients with a preexisting lung cavity from a variety of causes, such as pulmonary tuberc...
Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
