    Production and Purification of Dengue Virus-like Particles from COS-1 Cells
    Authors:  Jedhan Ucat Galula, Gwong-Jen J. Chang and Day-Yu Chao, date: 06/20/2019, view: 773, Q&A: 0
    [Abstract] Non-infectious virus-like particles (VLPs) containing dengue virus (DENV) pre-membrane (prM) and envelope (E) proteins have been demonstrated to be highly immunogenic and can be used as a potential vaccine candidate as well as a tool for serodiagnostic assays. Successful application of VLPs requires abundant, and high-purity production methods. ...
    DNA Immunization Using in vivo Electroporation for Generating Monoclonal Antibodies Against Mouse IL-9R
    [Abstract] Membrane proteins such as cytokine receptors and G protein-coupled receptors can be drug targets. Recently, we have generated specific monoclonal antibodies (mAbs) against the mouse IL-9 receptor (IL-9R) and found that IL-9R on memory B cells have critical roles in T-dependent immune response. So far, most antibodies against cell surface proteins ...
    Kinetic Analysis of Monoclonal Antibody Binding to HIV-1 gp120-derived Hyperglycosylated Cores
    Authors:  Jidnyasa Ingale and Richard T Wyatt, date: 10/05/2015, view: 5028, Q&A: 0
    [Abstract] Kinetic analysis of antibodies is one of the important studies for characterization of antibodies and screening of ligands. In our recent study (Ingale et al., 2014), we compared the antigenic profiles and binding characteristics of four HIV-1 envelope glycoprotein (Env) core immunogens using multiple monoclonal antibodies by Bio-Layer ...
    Fluorescence-linked Antigen Quantification (FLAQ) Assay for Fast Quantification of HIV-1 p24Gag
    Authors:  Marianne Gesner, Mekhala Maiti, Robert Grant and Marielle Cavrois, date: 12/20/2014, view: 6720, Q&A: 1
    [Abstract] The fluorescence-linked antigen quantification (FLAQ) assay allows a fast quantification of HIV-1 p24Gag antigen. Viral supernatant are lysed and incubated with polystyrene microspheres coated with polyclonal antibodies against HIV-1 p24Gag and detector antibodies conjugated to fluorochromes (Figure 1). After washes, the ...
    Binding Affinity Measurement of Antibodies from Crude Hybridoma Samples by SPR
    [Abstract] Surface Plasmon Resonance (SPR) is widely used to generate kinetic and affinity information on specific interactions between biomolecules. This technique is label-free and monitors the binding event in real-time. It is generally used for characterization of monoclonal antibody - antigen interactions. This protocol describes specifically the use of ...
    α2β1-integrin Clustering and Internalization Protocol
    [Abstract] α2β1-integrin clustering experiment can be used to trigger internalization of α2β1-integrin. When clustering is performed with sequential administration of primary and fluorescent secondary antibodies, the entry kinetics of integrin can be followed into the cell. The idea is first to allow binding of primary antibodies (recognizing the ...
    Chikungunya ELISA Protocol
    Authors:  Caitlin Mattos Briggs, Amanda Piper and Raquel Hernandez, date: 02/20/2014, view: 6675, Q&A: 0
    [Abstract] This protocol will result in the accurate qualitative measurement of anti-Chikungunya virus antibody (Ab) from infected mouse tissue or serum. This assay was developed by Dr. Caitlin Briggs, Arbovax, Inc. Chikungunya is a BL3 agent and should be handled in a biosafety level 3 laboratory under BL3 conditions. This protocol was used in the ...
    Surface Plasmon Resonance Analysis of Antigen-Antibody Interaction
    Authors:  Mitsuhiro Nishimura and Kazuyoshi Ikuta, date: 12/20/2013, view: 8916, Q&A: 0
    [Abstract] Molecular interaction between monoclonal antibodies (MAbs) and their recognized antigen is a fundamental event leading to the neutralization activity. Estimation of their binding affinity gives beneficial information to characterize the MAbs and to develop more effective MAbs. Surface plasmon resonance (SPR) analysis is a powerful tool to analyze ...
    Generation of Polyclonal Specific Antibodies
    Authors:  Maureen Wirschell and Mary E. Porter, date: 06/05/2013, view: 7469, Q&A: 0
    [Abstract] Generation of antibodies specific for a protein of interest is a common method in many disciplines. This protocol details the steps in production of a polyclonal antibody in rabbits using a bacterially expressed fusion protein as an antigen. The protocol is generated based on data presented in Wirschell et al.(2013).
    Antibody Purification from Western Blotting
    Author:  Lin Fang, date: 03/20/2012, view: 15861, Q&A: 2
    [Abstract] This protocol describes a method of purifying antibodies from sera with denatured antigens immobilized on western blot membranes. Advantages include (1) fast and easy; (2) purification of antibody with antigen in denatured form allows high yield in case antigen protein solubility is limited. Disadvantage is that possible antibodies that recognize ...
