Background: Pancreatic carcinoma is the fourth-leading cause of cancer death in the United States and due to its late presentation, only few patients would be candidates for the curative treatment of pancreactomy. Monoclonal antibodies have brought hope to targeted therapy.Objectives: To identify new biomarkers, a panel of monoclonal antibodies was genera...

alpha-fetoprotein (afp), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. monoclonal anti-afp antibodies are essential reagents in developing appropriate techniques for measurement of this protein. in this study, in order to produce anti-afp monoclonal antibo...

T-cell control of primary rotavirus infection and mucosal antibody responses to rotavirus was studied with monoclonal antibodies (MAb) to deplete gnotobiotic calves of CD4+, CD8+, BoWC1+, or both CD4+ and CD8+ lymphocytes prior to infection with rotavirus. Injection of these MAb produced specific reductions in circulating and tissue lymphocyte subpopulations. Following infection, control calves...

purification and isolation of cellular target proteins for monoclonal antibody (mab) production is a difficult and time-consuming process. immunization of mice with murine cell lines stably transfected with genes coding for xenogenic target molecules is an alternative method for mouse immunization and mab production. here we present data on transfection efficiency of some commercial reagents us...

A monoclonal anti-idiotypic (anti-Id) antibody, HF1.7, was generated against anti-Leu-3a, a mouse monoclonal antibody (mAb) specific for the CD4 molecule on human helper/inducer T lymphocytes. The anti-Id nature of HF1.7 was demonstrated by the following properties. (i) It reacted in a solid-phase immunoassay with anti-Leu-3a and not with a panel of irrelevant mouse mAbs. (ii) It partially inhi...

Using nuclear envelopes from Chinese hamster ovary (CHO) cells as an antigen, a mouse monoclonal antibody (IgM; designated mAb CHON211) that specifically binds to components of the nuclear pore complex (nucleoporins) was isolated. Immunofluorescence localization of the antigen recognized by mAb CHON211 revealed a punctate pattern restricted to the nuclear envelope; this pattern changed dramatic...

A simple rapid and reproducible procedure for transferring monoclonal antibodies into mammalian cells by electroporation is described. Two functionally different monoclonal antibodies (Mab 3F3 and Mab 2B4) specific for asparagine synthetase (EC 6.3.1.1) were used for electroporation into HeLa, HT-5, and L5178Y D10/R (L-asparaginase-resistant) cells. The conditions were optimized so that the via...

cystic echinococcosis (ce) is an infection caused by the larval stage of echinococcus granulosus. this is widely distributed through iran, where a variety of animals act as intermediate host. the immunogenic antigens (ag) of different compartments of the hydatid cyst have been already determined. one of these compartments is the laminated layer (ll). we have extracted a protein with the mw of 2...

Monoclonal antibody (mAb) therapeutics have tremendous potential to benefit patients with lung diseases, for which there remains substantial unmet medical need. To capture the current state of mAb research and development in the area of respiratory diseases, the Research Center of Respiratory Diseases (CEPR-INSERM U1100), the Laboratory of Excellence "MAbImprove," the GDR 3260 "Antibodies and t...

We recently found that CD82 inhibits matrix metalloproteinase 9 and augments adhesion of CD34(+) /CD38(-) acute myelogenous leukemia (AML) cells to the bone marrow (BM) microenvironment. The present study found that the use of an anti-CD82 monoclonal antibody (CD82 mAb) mobilized CD34(+) leukemia cells from BM into the peripheral blood in a humanized AML murine model. The use of CD82 mAb in com...
