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 ...

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...

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...

Background: Lassa virus (LASV) can cause severe acute systemic infection in humans. No approved antiviral drugs or vaccines are currently available. Antibody-based therapeutics considered a promising treatment strategy the management of LASV disease. Methods: We used chimeric Ifnar−/− C57BL/6 (Ifnar−/− Bl6) mice, lethal mouse model, to evaluate protective efficacy polyclonal antibodies purified...

background: the fc receptor like (fcrl) molecules belong to the immunoglobulin (ig) superfamily with potentially immunoregulatoryfunction. among the fcrl family fcrl2 and 4 are predominantly expressed on memory b cells and fcrl1 is a pan- b cell marker. to date, noligand has been identifid for the human fcrl1, 2 and 4 molecules.objectives: cloning, expression, purifiation and structural analysi...

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-...

background: radiolabeled polyclonal human immunoglubins are useful in the detection of inflammations. in this work a novel approach has been presented to use thallium-201 as a comlexed nuclide for the development of radioimmunoconjugates. materials and methods: thallium-201 (t1/2=3.04 d) in tl+ form was converted to tl3+ cation in presence of o3 in 6m hcl, controlled by rtlc/gel electrophoresis...
