Bacteriol. 90:302-308. 1965.-The Vi antigen and somatic antigen 9 were transferred to Salmonella typhimurium recipients by mating with S. typhosa Hfr TD-7, and the genetic determinants of these antigens were loc...

Background: Some antigens of H. pylori are excreted into the stool of infected people. These antigens can be used to detect the infection by immunoassays such as ELISA. Our aim was to identify these antigens by immunoblotting and affinity chromatography techniques. Methods: Four different antigenic preparations, namely, whole cell sonicate (WCS), outer membrane proteins (OMPs), cytoplasmic anti...

The integrin very late antigen, (VLA-4) alpha 4 beta 1 and its counter receptor vascular cell adhesion molecule 1 (VCAM-1) are involved in B cell maturation and pre-B cell attachment to bone marrow stroma cells. We have analyzed whether heat-stable antigen (HSA), a marker for immature leukocytes, is involved in such cell adhesion phenomena. HSA is a glycolipid-anchored, highly glycosylated surf...
