Two immunoelectrophoretically defined, heretofore unidentified beta(1)-globulins of human serum, provisionally designated beta(1C)- and beta(1A)-globulin, were isolated by means of preparative electrophoresis and chromatography on anion exchange cellulose. The sedimentation coefficient S(0) (20, w) of beta(1C)-globulin was shown to be 9.5 S, and that of beta(1A)-globulin, 6.9 S. Both proteins w...

INTRODUCTION With the increased utilization of immunohematology (IH) analyzers in the transfusion medicine, type, and screen policy is the method of choice. Still, the importance of routine crossmatching could not be overruled. Here, we tried to understand the clinical conditions and safety of red cell transfusion and their outcomes. MATERIALS AND METHODS This prospective study was conducted ...

The exact nature of the "rheumatoid factor" is unknown, but it appears to be an antibody-like substance composed of a gamma globulin complex of high molecular weight. Two groups of tests have been used to detect it: the haemagglutination test and the latex-fixation or Bentonite flocculation test. In the first group the indicator consists of sheep red cells with rabbit anti-sheep haemolysin as t...

The cold-insoluble globulin (CI-globulin) of human plasma has been highly purified. Starting with Fraction I-l, or plasma CryOpreCipitate, 2.1 M glyCine fractionation (15O) precipitated mainly fibrinogen; concentration of supernatant CI-globulin-enriched material (16% ethanol, -4’) was carried out prior to final purification by chromatography on diethylaminoethylcellulose. Chromatographically p...

BACKGROUND Basiliximab and anti-thymocyte globulin are widely used drugs for induction therapy after pediatric heart transplantation. The aim of this study was to determine whether any differences could be observed between basiliximab and anti-thymocyte globulin, with respect to long-term mortality, in a population of pediatric cardiac transplant recipients. METHODS AND RESULTS An analysis of...

When 11-day mice are fed with homologous or heterologous antibodies or with heterologous y-globulin, the maximum concentration of these proteins in their sera is reached 2 h later, irrespective of the amount or specificity of the proteins administered, or of the final con­ centration achieved. The relation between y (= relative titre of antibody, or concentration of heterologous y-globulin, att...

Recent studies have demonstrated that the factors responsible for the various serological reactions currently employed for the diagnosis of rheumatoid arthritis represent macroglobulins which, in the isolated state, have a corrected sedimentation coefficient of approximately 19S (1-5). In serum and plasma, these proteins exist as complexes with low molecular weight y-globtulins and show a highe...

Anti-thymocyte globulin is strongly reactive with platelets as measured by flow cytometric analysis. This reactivity appears to be independent of human leukocyte antigen (HLA) phenotype, is dose-dependent with saturation of platelet binding sites readily achieved with concentrations of horse anti-thymocyte globulin (ATG) at 0.25 mg per ml, and cannot be blocked with human anti-PLA1 antibody nor...
