INTRODUCTION Measurement of alloantibody titer to a red cell antigen (ABO titers) is an integral part of management of ABO incompatible kidney transplants (ABOiKT). MATERIAL AND METHODS There are different methods of titer estimation. Alloantibody detection by tube titration and Gel agglutination columns are accepted methodologies. It is essential to find the difference in titers between the ...

Hunt, D. E. (Charles V. Chapin Hospital, Providence, R.I.) and P. L. Carpenter. Sterols as components in the mating reaction of Hansenula wingei. J. Bacteriol. 86:845-847. 1963.-Agglutinative mating strains 5 and 21 of the yeast Hansenula wingei did not agglutinate after the cells of these two strains were treated with nystatin. The agglutination-inhibiting action of this antibiotic could not b...

The mechanism by which ristocetin induces platelet agglutination in the presence of the von Willebrand factor was studied by chemically altering ristocetin and a similar antibiotic, vancomycin, by reaction with a water-soluble carbodiimide in the presence of glycine methyl ester at pH 4.75. Altering ristocetin's phenolic groups (which are thought to be important in its peptide-binding propertie...

A total of 152 clinical isolates of Acinetobacter baumannii from 152 patients were identified by carbon source utilization tests and examined serologically. Polyclonal rabbit immune sera against A. baumannii strains were used in checkerboard tube agglutination tests, and 20 serovars were identified. One (serovar 19) cross-reacted with genospecies 3 (serovar 3), a closely related member of the g...

Microscopic agglutination of leptospiras was inhibited by the homologous type-specific main antigens. The result may indicate that the substance participating in the agglutination of leptospiras with antiserum is the type-specific main antigen.

background: visceral leishmaniasis (vl) is an endemic disease in some parts of iran. many techniques have been used for diagnosis of vl, among which the urine based la-tex agglutination test (katex) is a promising one. objective: to compare three diag-nostic tests of vl including katex, elisa and direct agglutination test (dat) in vl patients and healthy controls in the south west of iran. meth...

Measurement of von Willebrand factor antigen (VWF : Ag) levels is usually performed in a specialised laboratory which limits its application in routine clinical practice. So far, no commercial rapid test kit is available for VWF : Ag estimation. This paper discusses the technical aspect of latex agglutination method which was established to suit the purpose of estimating von Willebrand factor (...

We have investigated the relationship of concanavalin. A binding to the cell surface of normal and transformed cells and the subsequent agglutination of the transformed cells. At room temperature almost no differences could be detected in agglutinin binding between transformed and untransformed cells. At 0 degrees C, however, where endocytosis was negligible, the transformed cells bound three t...

Three commercially available rapid slide agglutination tests for the identification of Staphylococcus aureus were evaluated with 354 recent clinical isolates (165 strains of S. aureus). The test results of two latex agglutination products, SeroSTAT Staph (Scott Laboratories, Inc.) and Staphylatex (American Micro Scan), and one hemagglutination product, Staphyloslide (BBL Microbiology Systems), ...
