SFL 23.6: a monoclonal antibody reactive with CFU-E, erythroblasts, and erythrocytes

SFL 23.6: a monoclonal antibody reactive with CFU-E, erythroblasts, and erythrocytes.

A cytotoxic (IgG2b) monoclonal antibody (McAb) for a novel erythroid differentiation antigen was generated by hyperimmunizing young mice with mononuclear cells obtained from livers of 20- to 22-week-old fetuses. This McAb, designated SFL 23.6, shows an extremely well-defined reactivity with the cells of the erythroid lineage at all stages of maturation as evident from the labeling of morphologi...

A monoclonal antibody reactive with human eosinophils.

EO-1, an IgGl murine monoclonal antibody raised against human eosinophilic leukemia cells, reacts with eosinophils, basophils, platelets, and a few (2%) mononuclear cells but not with neutrophils. In the bone marrow, mature and immature eosinophils and basophils express the EO-1 antigen, whereas immature myeloid cells do not. The distribution of EO-1 antigen on leukemic cells is concordant with...

A monoclonal antibody (AB/3) reactive with human breast cancer.

Monoclonal antibody AB/3 was produced from a fusion of spleen cells of a human breast cancer cell-primed BALB/c mouse with the murine myeloma cell line P3-NS1-Ag4-1. The antibody reacted strongly with the plasma membrane of human breast cancer cells. Tissue sections of both malignant and benign human mammary carcinomas and tumors of non-breast origin as well as apparently normal tissues were te...

Successful Treatment of Refractory Thrombotic Thrombocytopenic Purpura with Rituximab, a Monoclonal Antibody: a Case Report

Thrombotic thrombocytopenic purpura (TTP) is mostly attributed to the presence of an autoantibody against ADAMTS-13, a metalloprotease that degrades ultralarge von Willebrand protein multimers. Accumulation of vWF multimers and systemic platelet aggregation lead to microangiopathic thrombosis, hemolytic anemia, and end-organ ischemia. Most patients respond to therapeutic plasma exchange (TPE), ...
