Background: The use of IgYs in a variety of methods in different areas of research, diagnostics, medical application and biotechnology should be considered widely. Objectives: Development of antibodies against extra cellular domain of influenza M2 (M2e) protein in egg yolk of laying hens. Methods: A Fusion construct harboring C-terminal of bovine heat shock protein 70 (Hsp70) and influenza M2e ...
A problem for the generation of polyclonal antibodies is the potential difficulties for obtaining a renewable resource due to batch-to-batch variations when the same antigen is immunized into several separate animals. Here, we have investigated this issue by determining the epitopes of antibodies generated from parallel immunizations of rabbits with recombinant antigens corresponding to ten hum...
Mycobacterium leprae-specific and polyclonal immunoglobulin G (IgG) subclass and IgE antibodies in leprosy patients across the histopathological spectrum were determined by using a quantitative enzyme-linked immunosorbent assay. Antibody responses to M. leprae sonicates were detected only in IgG1, -2, and -3 subclasses. Even at 100-times-lower dilutions, very little IgG4 and IgE antibody activi...
Monoclonal antibodies to purified human urinary kallikrein have been developed. Selection of antibody producing clones was based on 125I-kallikrein binding activity of hybridoma media in both radioimmunoassay and enzyme-linked immunosorbent assay. Three clones (2 IgG1, 1 IgG2b) were subcloned, characterized, and compared with the polyclonal antiserum generated in rabbits immunized with the puri...
phage-displayed random peptide libraries (rpl) provide a powerful technique for identification, structural and functional analysis of ligands for many different target molecules, including, antibodies, receptors or other proteins. this strategy has been verified to be an effective tool for research in immunology and successfully has been used to determine the target sequence for monoclonal and ...
Recent immune correlates analysis from the RV144 vaccine trial has renewed interest in the role of non-neutralizing antibodies in mediating protection from infection. While neutralizing antibodies have proven difficult to induce through vaccination, extra-neutralizing antibodies, such as those that mediate antibody-dependent cellular cytotoxicity (ADCC), are associated with long-term control of...
Transient receptor potential vanilloid type 1 (TRPV1) can be activated by multiple chemical and physical stimuli such as capsaicin, anandamide, protons, and heat. Capsaicin interacts with the binding pocket constituted by transmembrane regions 3 and 4, whereas protons act through residues in the prepore loop of TRPV1. Here, we report on characterization of polyclonal and monoclonal antibodies t...
Primary antibodies: Details of the antibodies used as primary reagents for immunostaining germinal center T cells are given in Table 1. The anti-SAP antibody used in this study was a commercial polyclonal reagent. A monoclonal antibody of the same specificity (anti-SH2D1A, Cell Signaling Technology, Inc, Boston, MA, Cat. No. 2805) was tested on tonsil sections and a limited number of diffuse la...
Antibodies are a class of biomolecules that has an important role in the immune system and lots of applications in biotechnological methods and in pharmaceutics. Production and purification of antibodies in laboratory animals is one of the first ways to manufacture of these prominent tools. The obtained antibodies from these process could be used in various types of bioassay techniques such as ...
background: the ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. the aim of this study was purification of mouse igg2a and production of polyclonal antibody against purified mouse igg2a subclass. materials and methods: mouse igg2a was purified by proa affinity. verification method of the purified antibody was sds-...
