The determination of immunoglobulin light chain restriction using monoclonal and polyclonal antibodies is a rapid method for the detection of a neoplastic B-cell-population. Cytocentrifuge preparates of mononuclear blood cells from 42 patients with chronic B-lymphoid leukaemia and of lymph node aspirates from 24 patients with B-non-Hodgkin's lymphoma were examined using the alkaline phosphatase...

Antibodies are known to affect the morphology, growth, and metabolism of mollicutes and thus may serve as candidate molecules for a plantibody-based control strategy for plant-pathogenic spiroplasmas and phytoplasmas. Recombinant single-chain variable fragment (scFv) antibodies are easy to engineer and express in plants, but their inhibitory effects on mollicutes have never been evaluated and c...

BACKGROUND Detection of Trypanosoma cruzi antigens in clinical samples is considered an important diagnostic tool for Chagas disease. The production and use of polyclonal antibodies may contribute to an increase in the sensitivity of immunodiagnosis of Chagas disease. METHODOLOGY/PRINCIPAL FINDINGS Polyclonal antibodies were raised in alpacas, rabbits, and hens immunized with trypomastigote e...

The interleukin (IL)‑12 family cytokines have been examined as therapeutic targets in the treatment of several autoimmune diseases. Our previous study showed that a novel IL‑12 family cytokine, IL‑39 (IL‑23p19/Ebi3) mediates inflammation in lupus‑like mice. In the present study, the effect of anti‑mouse IL‑39 polyclonal antibodies on autoimmune symptoms in lupus‑like mice was investigated. Rabb...

Pemphigus vulgaris (PV) is an autoimmune epidermal blistering disease caused by autoantibodies directed against the desmosomal cadherin desmoglein-3 (Dsg3). Significant advances in our understanding of pemphigus pathomechanisms have been derived from the generation of pathogenic monoclonal Dsg3 antibodies. However, conflicting models for pemphigus pathogenicity have arisen from studies using ei...

Laboratory detection of specific foot-and-mouth disease virus (FMDV) is routinely carried out by ELISA and RT-PCR. Identification and serotyping of FMDV by ELISA requires polyclonal antibodies raised in rabbits and guinea pigs. The polyclonal antibodies have certain disadvantages such as batch to batch variation, inconsistent yields of antibodies and limited quantity of serum obtained from indi...

We investigated two techniques of immunoblotting--the Western blot and the dot blot--for use in detecting prostatic acid phosphatase (PAP, EC 3.1.3.2). We used polyclonal antisera to human PAP, produced in rabbits by hyperimmunization with purified PAP, and PAP-specific monoclonal antibodies in the immunoenzymatic protocols. We conclude that PAP can be readily detected by Western blots with use...
