The use of the agar gel diffusion technique has established the presence of three distinct antigenic reactions in the sera of Ad. 12 tumor-bearing hamsters. Only one of these antigens is directly demonstrable in the tumor. This "tumor" antigen is also formed during early stages of the infectious cycle in tissue culture cells. Other antigens present in the tumor, but only demonstrable indirectly...
Vi antibody response of rabbits varied depending on whether Vi antigen was administered in particulate or soluble state. Vi antigen in particulate form induced hemagglutinins, bacterial agglutinins, and passive cutaneous anaphylaxis (PCA) antibodies, whereas soluble Vi antigen induced only hemagglutinins. Guinea pigs passively sensitized with antisera against particulate Vi antigen gave PCA rea...
BACKGROUND Non-ABO alloantibodies are frequently implicated in hemolytic transfusion reactions and are a leading cause of transfusion-related mortality. Detection of clinically significant non-ABO alloantibodies is reliant on an antibody screen, which is prone to clerical, technical, and reagent error. Data on the frequency of false-negative antibody screens due to the occurrence of these error...
Background: Lung carcinoma is a multiple type cancer comprising of small cell and non-small cell carcinomas (NSCLC). For therapeutic and diagnostic purposes, serum monoclonal antibodies have been produced against lung cancer. Objective: To charac-terize a murine monoclonal antibody (ME3D11) reactive with human NSCLC. Methods: A murine monoclonal antibody (ME3D11) reactive with human NSCLC was s...
Guinea pig 7Sgamma(2) antibodies were demonstrated to fix complement in the presence of antigen and to sensitize antigen-coated, tanned erythrocytes for lysis in the presence of complement; guinea pig 7Sgamma(1) antibodies did not participate in these reactions. Gamma-2 antibodies were more efficient in provoking hemorrhagic necrosis in reverse passive Arthus reactions than equal amounts of non...
Background: Streptococcus pneumoniae is a common cause of respiratory infection. Pneumococcal upper respiratory tract infection (URTI) in children is seldom bacteremic. Determination the prevalence of S.pneumoniae infections in children with URTI using rapid urinary antigen test (BINAX now) and titration of serum pneumolysin antibody (added to conventional culture) was the object of this study....
We demonstrate continuous label-free detection of two cardiac biomarker proteins (creatin kinase and myoglobin) using an array of microfabricated cantilevers functionalized with covalently anchored anti-creatin kinase and anti-myoglobin antibodies. This method allows biomarker proteins to be detected via measurement of surface stress generated by antigen–antibody molecular recognition. Referenc...
Glucanase (endo-beta-1, 3-glucan 3-glucanohydrolase, EC 3.2.1.6, laminarinase, callase) and chitinase (poly-beta-1, 4-[2-acetamido-2-deoxy] -d-glucoside glycanohydrolase, EC 3.2.1.14) were extracted from ethylene-treated bean (Phaseolus vulgaris L. cv. Red Kidney) leaves and purified on hydroxyapatite and carboxymethyl Sephadex columns. The glucanase prepared was homogeneous as judged by analyt...
Double diffusion in agarose was employed for the characterization of a soluble nucleoprotein antigen that gave precipitin reactions with sera from patients with systemic lupus erythematosus. The soluble antigen that was isolated from calf thymus nuclei was demonstrated by enzyme degradation and ultracentrifugation studies, and by immunologic analysis, to be a complex of deoxyribonucleic acid an...
Advanced and Commonly Used Serological Techniques for Detection and Diagnosis of Plant Virus: Review
Plant diseases caused by viruses are the most menace to sustainable agriculture, leading numerous billion dollars in losses annually. Proper and accurate detection of plant is always key developing appropriate solutions manage economic them. Advances technology have simplified tools available detect diagnose at a time when control measures should be used. Currently, nucleic acid serological bas...
