ISO-AGGLUTINATION AND HETERO-AGGLUTINATION OF SPERMATOZOA
The Biological Bulletin, 19221. Iso-agglutination occurs in the black chiton, Katharina tunicata. This is the first report of unmistakable iso-agglutination of spermatozoa of a mollusc; also of iso-agglutination of spermatozoa which are inactive in sea-water.2. The iso-agglutinated masses of spermatozoa of K. tunicata differ from those of sea-urchins and of Nereis.

Journal of Immunological Methods, 1974
Abstract The capillary assay of agglutinating-like anti-leukocyte antibodies appears to be a simple, reliable and sensitive technique. A number of factor iin measuring anti-leukocyte agglutinins were investigated to determine the optimum conditions for the method. Concentrations of Ethylene-dinitrilotetraacetic acid (EDTA) and calcium, capillary tube

Mixed Agglutination with Platelets
International Archives of Allergy and Applied Immunology, 2009Platelet layers firmly adhering to the glass surface were obtained by allowing human platelets to sediment onto the wall of test tubes or onto glass slides and ‘fixing’ them by means of a 2% formaldehyde solution. Mixed agglutination tests with these platelet preparations were performed in following the procedure used for studies on monolayer cell ...

Sperm Agglutination and Infertility
JAMA: The Journal of the American Medical Association, 1973To the Editor.— I would like to comment on the recent article by Pacheco-Romero et al (224:849, 1973), dealing with the relationship of spermagglutinating activity and female infertility. I fear that this report may cause some confusion, because we may question the reliability of the exact technics that were used, and also because of the logic of the ...

Scandinavian Journal of Immunology, 1973
In human sera showing elevated levels of IgM, the serum agglutinators may be of both IgG and IgM classes. When the quantity of IgG is very low, these antibodies may be solely of the IgM class. Elevations in IgM levels subsequent to loss of IgG through the kidney, as in nephrosis, and elevations in all immunoglobulin levels, as observed in severe ...

Agglutination of Bacteria by Hemoglobin
Acta Rheumatologica Scandinavica, 1957SummaryA number of antigens from gram-positive bacteria, especially streptococci, are agglutinated by hemoglobin from human, sheep, horse, rabbit and guinea pig blood.The agglutination factor, to which the globin part of the hemoglobin is ascribed, can be removed by various antigens from hemoglobin solutions.Experiments with various antigen fractions ...

Sexual Agglutination in Chlamydomonads
1985Publisher Summary The way cells communicate with each other, interact, and co-ordinate their activities is a fundamental issue in developmental biology. This is particularly true in multicellular organisms, where the controlled division of labor among cells determines form and function of the whole organism as well as its parts.
