Antigen detection during Western blotting commonly utilizes a horseradish peroxidase-coupled secondary antibody and enhanced chemiluminescent substrate. We utilized this technique to examine the impact of green tea-derived polyphenols on the binding of egg white protein-specific IgE antibodies from allergic human plasma to their cognate antigens. Our experiments unexpectedly showed that green t...
A method is described for the demonstration of specific immunoglobulin in plasma cells and other lymphoid cells in sections taken from routine surgical histology specimens which have been formalin fixed and paraffin embedded. An indirect sandwich technique was employed using specific rabbit antihuman immunoglobulin antisera (anti-K, L, G, A, and M) and a swine antirabbit serum Ig G, conjugated ...
Immunodetection techniques are dependent on enzyme-protein conjugates for the visualisation of antigen-antibody complexes. One of the most widely used is the avidin-biotin-peroxidase complex (ABC) method. The present study demonstrates that direct treatment of goldfish and salamander retinal sections with ABC, followed by an incubation with the chromogenic substrate 3,3-diaminobenzidine tetrahy...
BACKGROUND Staphylococcal protein A (SPA) is a cell wall component of Staphylococcus aureus that binds to different IgG subclasses of human and several animal species. This bacterial protein can be used as an antibody detector in various immunological assays or as an isolation reagent for the purification of antibody molecules via immuno-chromatography procedures. OBJECTIVES Molecular cloning...
background: rh (rhesus) is a highly complex blood group system in man deeply rooted in transfusion medicine. isolation of rhd from cord blod, cloning and expression of recombinant rhd antigen in bacterial expression system was the aim of this study. methods: total rnas were extracted from cord blood (o + ). the quality of rna was determined by electrophoresis. in order to obtain coding sequen...
A dot immunobinding assay ( DIA) was used for a quantitative and qualitative assay of rubella antibody. Purified antigen and conjugated anti-human immunoglobulin (RAHlg) were prepared. Nitrocellulose paper dotted with the antigen was added to serially diluted sera or blood samples. The reacting antibodies were visualized by a peroxidase system. Development of a colored insoluble substrate ...
Background: Hypothyroidism was the diagnosed and treated as a result of health related quality life issues. The aim this study that to evaluate effect IL-36 γ, Tg-Ab TOP-Ab in Hashimoto’s Thyroiditis (HT). Study design: This cross sectional conducted at Rawal Institute sciences, Islamabad duration six month, from April 2022 September 2022. Methods: A total number patients n=150 which divided in...
Metformin has been found to reduce elevated gonadotropin levels. Hashimoto’s thyroiditis is the most common thyroid disorder in iodine-sufficient areas, and it often develops postmenopausal women. The aim of this study was investigate whether autoimmune determines impact metformin on gonadotrope secretory function. Two matched groups women were studied: 35 with euthyroid (group A) without disor...
Monospecific antiserum to human placental alkaline phosphatase was purified by immunoabsorption and labeled with horseradish peroxidase. The binding of this labeled antibody to membrane fragments prepared from placental and tumor tissue was measured using agarose gel filtration to separate bound antibody. The antibody bound only to membrane fragments which contained placental phosphatase, and t...
