Abstract Background: In molecular approach, serum of camel contains a unique type of antibodies devoid of light chains since the light chain is missing, the heavy-chain antibodies should bind their antigen by one single domain, the variable domain of the heavy immunoglobulin chain. Vascular endothelial growth factor receptor-2 (VEGFR-2) is one of the important proteins in angiogenesis which...
Compared to classical antibodies, camel heavy chain antibodies (HCAbs) are smaller in size due to lack of the light chain and the first constant domain of the heavy chain (CH1 region). The variable regions of HCAbs (VHHs) are more soluble and stable than that of conventional antibodies (VHs). Even with such simple structure, they are still functional in antigen binding. Although HCAbs have been...
Chicken egg yolk antibodies (IgY) against camel immunoglobulins were generated and their specificity was shown by double immunodiffusion, immunoelectrophoresis, and Western blotting. Anti camel antibodies specifically react to camel antibodies in immunodiffusion and immunoelectrophoresis were demonstrated. Western blotting revealed that IgY antibodies recognize the heavy chain in a number of ma...
mammalians express several subclasses of the igg molecule. in human being there are four homologous igg subclasses, each of which is structurally unique and has different functions. quantification of igg subclasses is fundamental to clinical assessment and diagnosis of many diseases as such assessments depends on the availability of subclassspecific antibodies (abs), particularly monoclonal ant...
Background: Single domain antibodies from camel heavy chain antibodies (VHH or nanobody), are advantages due to higher solubility, stability, high homology with human antibody, lower immunogenicity and low molecular weight. These criteria make them candidates for production of engineered antibody fragments particularly in transgenic animals. Objective: To study the development of transgenic ch...
Background: Diarrhea caused by Escherichia coli is a major cause of morbidity and mortality in young animals. Few treatment options are available, mainly antibiotic therapy increasingly limited by resistance to commonly used drugs.Objectives: The aim of this work was to develop immunotherapy based on the use of camel VHH antibody fragments, or nanobodies,...
PURPOSE The production of camel heavy-chain antihuman IgE (huIgE) that has the potential to block IgE-FcεRI interaction and histamine release by basophils. METHODS Camels were immunized with a synthetic loop peptide (SLP) designed in a multiple antigen peptide system (MAPS) forming SLP-MAPS immunogen. Camel polyclonal antibodies (PCAs) were produced, purified, characterized using Protein A & ...
objective(s): as t-cell immunoglobulin and mucin domain 3 (tim-3) is an immune regulatory molecule; its blocking or stimulating could alter the pattern of immune response towards a desired condition. based on the unique features of nanobodies, we aimed to construct an anti-tim-3 nanobody as an appropriate tool for manipulating immune responses for future therapeutic purposes. materials and meth...
