A new monoclonal antibody, CSLEX1, directed against sialylated Lewisx was tested in parallel with a monoclonal antibody, CSLEA1, directed against sialylated Lewisa antigen. In tests with a solid-phase radioimmune sandwich assay, the sialylated Lewisx monoclonal antibody detected sera from certain cancer patients that were negative with the sialylated Lewisa monoclonal antibody. Some sera from c...

Five patients treated with intraperitoneal 131I-labeled mouse monoclonal antibody for ovarian cancer also received i.v. exogenous polyclonal human anti-murine immunoglobulin antibody. The pharmacokinetics of 131I-labeled monoclonal antibody in these patients were compared with those of 28 other patients receiving i.p.-radiolabeled monoclonal antibody for the first time without exogenous human a...

Background: Avian influenza viruses (AIVs) including the subtype H9N2 cause considerable financial losses to poultry industries. Rapid and accurate diagnosis of avian influenza (AI) infection is important in control and eradication programs. OBJECTIVES: The aim of this study was to produce monoclonal antibodies (MAbs) specific for the nucleocapsid protein )NP (of AIV H9N2 subtype to improve dia...

Cold agglutinin disease is a rare autoimmune hemolytic anemia characterized by hemolysis that caused activation of the classic complement pathway. Sutimlimab, humanized monoclonal antibody, selectively targets C1s protein, C1 complex serine protease responsible for activating this

Introduction: Pembrolizumab (Keytruda®) is a potent and selective humanized monoclonal immunoglobulin antibody that blocks programmed cell death-1 on T cells, augmenting the antitumor immune response. an approved adjuvant therapy for treating metastatic melanoma.

objective(s):multi-epitopic protein vaccines and direction of vaccine delivery to dendritic cells (dcs) are promising approaches for enhancing immune responses against mutable pathogens. escherichia coli is current host for expression of recombinant proteins, and it is important to optimize expression condition. the aim of this study was the optimization of multi-epitopic hiv-1 tat/pol/gag/env ...

A monoclonal antibody (M2A, IgG2a) was produced against a cultured human ovarian epithelial adenocarcinoma cell line, HEY. Monoclonal antibody M2A reacted with a glycoprotein of molecular weight 40,000 on the surface of HEY cells. The affinity constant of the monoclonal antibody M2A for HEY cells was 10(9) M-1, and the number of binding sites on HEY cells was 2 X 10(4) per cell. The monoclonal ...
