STUDIES ON THE VIRAL HEMAGGLUTINATION INHIBITORS

Studies on Avian Viral Infections in Iran

Method for extracting viral hemagglutination-inhibiting antibodies from the nonspecific inhibitors of serum.

Various methods are used to remove nonspecific inhibitors from sera before titering viral hemagglutination-inhibiting antibodies. These methods have several undesirable features; some are tedious and time-consuming, some remove antibody along with nonspecific inhibitors, and different techniques are usually required to remove the nonspecific inhibitors for different viruses. This communication ...

Studies on hemagglutination activity of caprine herpesvirus-1

The aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(CpHV-1) and their application for CpHV-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. CpHV-1 hemagglutination activity was proved only with mouseerythrocytes, PBS and saline solutions at 4°C and 22°C. In vaccinated animals, goats and bucks withresp...

Structure studies on the myxovirus hemagglutination inhibitor of human erythrocytes.

We have previously (l-3) described the isolation from erythrocyte stroma of a potent inhibitor of hemagglutination by influenza viruses. The inhibitor has been shown to be a glycoprotein, homogeneous by the criteria of paper and moving boundary electrophoresis, ultracentrifugal analysis, column chromatography on various grades of Sephadex, and end group analysis. It is a glycoprotein of approxi...

Application of freeze-dried monkey erythrocytes to measles viral hemagglutination and hemagglutination-inhibition tests.

Erthrocytes collected from monkey species including grivet, rhesus, and cynomolgus monkeys were stabilized by fixation with glutaraldehyde of a low concentration and were freeze-dried in vacuo. These freeze-dried erythrocytes were compared with fresh erythrocytes for measles viral hemagglutination and hemagglutination inhibition and could be used in both tests instead of fresh erythrocytes. The...
