Antibodies are essential tools of biomedical and biochemical researches. Polyclonal antibodies are produced against different epitopes of antigens. Purified F(ab')2 can be used for animal's immunization to produce polyclonal antibodies. Human immunoglobulin G (IgG) was purified by ion exchange chromatography method. In all stages verification method of the purified antibodies was sodium dodecyl...
Abstract Despite ongoing efforts to characterize the host response toward SARS-CoV-2, a major gap in our knowledge still exists regarding magnitude and duration of humoral response. Analysis antibody mild versus moderate/severe patients, using new developed quantitative electrochemiluminescent assay for detecting IgM/IgA/IgG antibodies SARS-CoV-2 antigens, revealed rapid onset IgG/IgA antibodie...
We previously evaluated Wilms' tumor gene 1 (WT1) peptide vaccination in a large number of patients with leukemia or solid tumors and have reported that HLA-A*24:02 restricted, 9-mer WT1-235 peptide (CYTWNQMNL) vaccine induces cellular immune responses and elicits WT1-235-specific cytotoxic T lymphocytes (CTLs). However, whether this vaccine induces humoral immune responses to produce WT1 antib...
The application of food-specific IgG antibody detection in allergy dermatoses was explored. 181 patients with allergy dermatoses were diagnosed from January to September 2014 and 20 healthy subjects were selected. Fourteen kinds of food-specific IgG antibodies were detected by ELISA method among all the subjects. The positive rates of IgG antibody of the patient group and the healthy group were...
background: mild to severe post-transfusion adverse reactions have been reported in a proportion of immunodeficient patients receiving intravenous immunoglobulin (ivig). anti-iga antibody has been proposed to be associated with development of such reactions. objective: to assess the association between anti-iga levels of different isotypes and adverse reactions induced in immunodeficient pati...
BACKGROUND Anti-carbamylated protein (anti-CarP) antibodies have recently been reported to occur in around 45% of rheumatoid arthritis (RA) patients and to have prognostic and diagnostic properties. At present, the breadth and molecular make-up of the anti-CarP antibody response is ill defined. To understand the anti-CarP antibody immune response and potential immune effector mechanisms it can ...
Different clinical outcomes of tuberculosis can be related to the balance between cell-mediated and humoral immunity. In this prospective study we examined the humoral immune responses to recombinant and native mycobacterial antigens in relation to clinical presentations of pulmonary TB. Two hundred and fifteen serum samples were examined including: non-cavitary (n=120), cavitary (n=65), caseou...
Hypogammaglobulinemia (serum IgG lower than 2 SD below the age-matched mean) and clinical symptoms such as increased susceptibility to infection, autoimmune manifestations, granulomatous disease, and unexplained polyclonal lymphoproliferation are considered to be diagnostic hallmarks in patients with common variable immunodeficiency (CVID), the most frequent clinically severe primary immunodefi...
Background/aim: In this study, we aimed to investigate different types of celiac antibodies in psoriasis patients and see if the presence was associated with other variables. Materials methods: We included plaque who were followed up our dermatology clinic between February 2019 2021 added a healthy control group for comparison. The studied serum antitissue transglutaminase (tTG)-IgA, tTG-IgG, a...
IgG antibodies are glycoproteins containing a branched sugar moiety attached to the asparagine 297 residue in the antibody constant region (Fc). This glycan is essential for maintaining a functional Fc structure, which is a prerequisite for antibody-mediated effector functions, such as the interaction with cellular Fc receptors or the complement component C1q. Variations in the composition of t...
