We have studied functional alteration of immunocytes in mice following inoculation of Toxocara canis second stage larvae. Results indicated depression of lymphocyte blastogenesis in response to concanavalin-A, phytohemagglutinin and allogeneic non B-cells; however, B-cell polyclonal activation was not affected as indicated by the production of total IgG. In contrast, frequency of antibody ...

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 ...

OBJECTIVE B7 (CD80/CD86) molecules are over-expressed in patients with SLE. However, it is not clear whether CD80/CD86 molecules are involved in the pathogenic autoantibody production specifically or in the polyclonal antibody production in human SLE. The present study was carried out to characterize B7 molecules on B cells in autoantibody production. METHODS Expression of costimulatory molec...

Background: Currently immune checkpoint pathways of PD1-PD-L1 is being used to treat lung cancer and PD-L1 served as predictive biomarker. Investigations expression a target immunotherapy in specimens Indonesia needed. This study aimed evaluate resected using immunohistochemistry techniques. Methods: Thirty surgically sample from patients were obtained. The whole stained by techniques automatic...

Monoclonal antibody against P. mameffei yeast secreted antigen was produced in order to develop a serological test for penicilliosis marneffei. The yeast form of P. marneffei was cultured in brain heart infusion broth at 37 degrees C for 7 days. A secreted antigen was prepared, partially purified from culture supernatant and subsequently immunized in a BALB/c mouse. Mouse monoclonal antibody wa...

BACKGROUND Induction immunosuppression is perceived as an expensive therapy, so is often given only to select patients. This study evaluated the cost-effectiveness of antibody induction comparing interleukin-2 receptor antagonists (IL2Ra) to standard therapy with no induction or induction with polyclonal antibodies. METHODS A Markov model was developed to estimate costs and health outcomes [s...

Polyclonal antibodies against the Hop1 phospho-T318 and phospho-S298 were obtained as following: The α-pT318 polyclonal antibody [Cambridge Research Biochemicals] was obtained by immunising two rabbits with the antigenic [C]-Ahx-ASIQP-[pT]-QFVSN where C is a cysteine residue added at the N-terminus of the peptide, Ahx is aminohexanoicacid and pT is a phosphorylated threonine residue. Upon bleed...

Polyclonal antibodies raised against 4-phosphothiophen-2-yl alanine 2a, a novel five-membered ring analogue of phosphotyrosine, showed high selectivity for phosphotyrosine and no cross-reactivity with other phosphorylated amino acids. Western blots showed that the polyclonal was similarly effective, but different in selectivity, to a commercially available monoclonal antibody.

Inhibitors of clotting factors occuring in humans are often antibody molecules synthesized in response to exogeneous proteins used in replacement therapy. Extensive studies of inhibitors to factor VIII indicate such antibodies may be monoclonal or polyclonal in nature. To date, only one factor IX inhibitor has been subjected to detailed immunochemical analysis and it appears to be a monoclonal ...

Monoclonal anti-idiotypic antibodies (3C3F3E4 and 10D3F8H7) that interact with platelet activating factor (PAF) receptors were generated using an auto-anti-idiotypic approach by immunizing mice with an aldehydic analog of PAF coupled to bovine thyroglobulin. The resulting hybridomas were screened for anti-idiotypic antibody (anti-anti-PAF) with F(ab')2 fragments of affinity-purified polyclonal ...
