With the aim of the production of human factor VIII antigen and its corresponding antibody an epitope coding fragment of the light-chain of hFVIII, fused to a His6-tag, was isolated and over-expressed in Escherichia coli. The over-expressed hFVIII-epitope containing peptide was confirmed by its reaction with a rabbit serum directed against native hFVIII as well as antiHis6-tag antibody. An expr...

Background: Human epidermal growth factor receptor 2 (HER2) has a crucial role in several malignancies. The extracellular domain of HER2 (HER2-ECD) has been extensively employed as an important target in passive and active immunotherapy. Isolated recombinant prokaryotic HER2-ECD subdomains were previously found to be ineffective in inducing anti-tumor antibody response. Objective: To employ rec...

Fc fragments derived from human immunoglobulin were found to be capable of inducing both a proliferative and polyclonal antibody response in human peripheral blood lymphocyte cultures. The cell population proliferating in response to Fc fragments belongs to the B cell lineage. Expression of polyclonal antibody formation requires the presence of both adherent monocytes and T cells. The role of t...

in this study we produced and purified a high titer of specific and high affin¬ity fab fragments of anti-digoxin antibody. immunization of rabbits with a conju¬gate of the cardiac glycoside digoxin, coupled by a periodate oxidation method to the amino group of lysine in bovine serum albumin resulted in the production of this type of high titer digoxin-specific antibodies with exceptionally high...

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...

Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. Objective: In this study we aim to measure,...

background: rabies virus (rabv) is a deadly neurotropic virus that causes the disease of rabies in humans and animals. l protein is one of the large structural protein of rabies virus, which displays multiple enzymatic activities, and is required for viral transcription and replication.objectives: a truncated l protein of rabies virus is being cloned, expressed and purified to produce relevant ...

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 S...

Many different radiolabeled antibodies have been used for radioimmunotherapy and radioimmunoscintigraphy of human diseases in animal experiments. In order to study the in vivo tissue distribution of antibody, we labeled human nonspecific polyclonal IgG with Na125I using chloramine-T method. An animal model was developed by injecting turpentine in the posterior left thigh of Balb/c mice. Tissue ...
