Effect of specific antisera uponStreptococcus mutansadherence to saliva-coated hydroxylapatite

Preparation of Type-specific Antisera to Reoviruses.

Preparation of type-specific antisera to reoviruses has been handicapped by the ubiquitous distribution of these viruses and frequent occurrence of reovirus antibodies in many species of animals. Antisera prepared in rhesus monkeys at this laboratory have shown extensive crossings between the three types (Table 1). Similar crossreactions have been observed in antisera prepared in rabbits (A. M....

Inhibition of bacterial adherence to saliva-coated through plant lectins.

In the present study, we evaluated the ability of lectin from Talisia esculenta (TEL) and a protein from Labramia bojeri seeds (Labramin) to inhibit adherence of microorganisms and exert antimicrobial effects. The minimum inhibitory and bactericidal concentrations of these proteins were determined using 5 species of bacteria: Streptococcus mutans UA159, Streptococcus sobrinus 6715, Streptococcu...

Biologic activity of digoxin-specific antisera.

Digoxin-specific antibodies are capable of removing essentially all intracellular digoxin from rat renal cortical slices or from human erythrocytes. In removing digoxin from erythrocytes, these antibodies are capable of reversing an effect of the drug on cellular potassium transport. This study provides direct evidence that antibodies are capable of removing, and thereby reversing the biologica...

Studies on the Production of Specific Hyperimmune Antisera Against Type A F.M.D. Virus

Antisera specific for D2 dopamine receptors.

Antisera have been raised against two peptides from the sequence of D2 dopamine receptors: peptide 1 from the predicted second extracellular loop and peptide 2 from the predicted third intracellular loop. The antisera recognize specifically a 95 kDa band in Western blots of several bovine brain regions, which corresponds to the denatured D2 dopamine receptor, whereas in recombinant CHO cells ex...
