Identification of New Antigens Belonged to Cattle B Blood Groups

Relationship of blood groups to pemphigus: Do blood group antigens have a biological role? A Case-control study

Background: ABO blood group antigens may play a role in the pathophysiology of certain diseases. Several studies have investigated the relation between blood group and autoimmune disorders. In this research, we evaluated the associations between ABO blood types and rhesus (Rh) factor in pemphigus patients.Methods: In this case-control, hospital-based study, we evaluated the prevalence of blood ...

Evidence for two new systems of blood groups in cattle.

I N 1962, STORMONT surveyed 66 known antigenic factors of the red cells of cattle. These factors were designated A, B, C, . . . Z, A’ . . . etc., and a few new ones were designated by number. Peculiar constellations of factors occurred nonrandomly in population data ( STORMONT, OWEN and IRWIN 1951 ) and family studies confirmed the genetic transmission of particular groups of factors as entitie...

Identification of protein antigens of group B streptococci, with special reference to the Ibc antigens

The protein antigens of prototypes of five types of group B streptococcal strains were extracted with HCl or Triton X-100, separated by sodium dodecyl sulfate polyacrylamide electrophoresis, transferred to nitrocellulose, and examined by immunochemical staining. The Ibc proteins are shown to consist of at least two distinct protein antigens and their breakdown products. One antigen, the "beta" ...

Relationship of blood groups to disease: do blood group antigens have a biological role?

Identification of blood group A and B antigens in human glycophorin.

Glycophorin A (GPA), the major sialoglycoprotein of human erythrocyte membranes, was isolated separately from blood group A and B erythrocytes using phenol-water extraction. After purification, performed as gel filtration in the presence of SDS, two glycophorin samples GPA-A and GPA-B were run, in duplicate, in SDS-PAGE and electroblotted onto Immobilon P. After staining with 1) anti-glycophori...
