BACKGROUND & OBJECTIVE Monoclonal antibodies against red blood cell antigens used in research and as diagnostics in India are commercially procured from western countries. Indigenously generated potent clones are not available in India. Hence, the objective of the present study was to raise potent murine monoclonal antibodies against A, B and H blood group antigens indigenously and establish a ...

We previously demonstrated that patients with carcinoembryonic antigen [CEA]-producing neoplastic tumors, treated with murine monoclonal antibody to CEA, produced antibodies directed against the constant regions [human anti-mouse antibody (HAMA)] and the idiotypes [anti-Id] of these murine immunoglobulins. In this study, we describe a method for analyzing the presence of such antibodies in the ...

Background: Different methods have been used for characterization of Leishmania promastigotes. Monoclonal antibodies are useful in characterization of   Leishmania spp . both amastogotes and promastigotes. Objective: Comparing the characterization of   Leishmania spp. promastigotes with immunoperoxidase test (Avidin-Biotin) techniques and an indirect immunofluorescent assay (IFA).   Methods: Ap...

In this issue of Blood, Rothe et al introduce a new principle of targeted Hodgkin lymphoma (HL) immunotherapy in their report from a phase 1 study of the bispecific anti-CD30/CD16A antibody construct AFM13.

BACKGROUND & OBJECTIVE The antigen H present on the surface of red cells in varying concentration, is maximum in O group red cells, but absent in Bombay phenotype individuals. This differentiation is generally detected by seed extracts of Ulex europaeus. The titre of such an extract is usually low and is subjected to batch variation. Hence, we carried out this study to raise potent murine monoc...

Previous studies have shown that treatment of mice in vivo with xenogeneic anti-idiotype produced against a monoclonal anti-H-2Kk antibody, 11-4.1, leads to the induction of molecules (Id') that inhibit the binding of anti-idiotype to idiotype. To investigate the nature of these Id' molecules, spleens from such anti-idiotype-treated mice were fused with the SP2/0 myeloma to produce monoclonal I...

Evolution of therapeutic monoclonal antibodies significantly benefited from the recombinant DNA technologies that are used to generate chimeric, humanized, and human versions of monoclonal antibody to reduce the problem of immunogenicity and neutralization, as well as from understanding mechanisms of action mediated by monoclonal antibodies (Nelson et al., 2010; Reichert, 2009; Ranson & Sliwkow...

Background and aims: Coeliac disease (CD) is a multifactorial disorder which has an autoimmune component characterised by the occurrence of disease specific autoreactive antibodies against the enzyme tissue transglutaminase (tTG). The aim of this study was to investigate whether binding of antibodies to the enzyme influences tTG activity. Methods: tTG activity was assayed in the presence of imm...

A monoclonal anti-idiotypic antibody (H10E4C9F) that interacts with the aldosterone receptors was generated using an auto-anti-idiotypic approach by immunizing a mouse with a 3-O-carboxymethyloxime of aldosterone coupled to bovine serum albumin. This antibody, an IgG1, displayed internal image properties of aldosterone and was considered as an Ab2 beta according to the following criteria. (i) H...
