A method was developed for making viable counts of Campylobacter fetus (Vibrio fetus) in tube cultures using a medium containing alkaline hematin and incubation in a carbon dioxide incubator.

Thirteen forms of glutathione S-transferase were isolated from human liver in high yields by glutathione-affinity chromatography and chromatofocusing. Apparent isoelectric points ranged from 4.9 to 8.9 and included neutral forms. All 13 forms appeared to be identical immunochemically in a quantitative enzymelinked immunosorbent assay. These forms were immunochemically distinct from the major ac...

BACKGROUND Hemozoin (Hz) is a heme crystal that represents a vital pathway for heme disposal in several blood-feeding organisms. Recent evidence demonstrated that β-hematin (βH) (the synthetic counterpart of Hz) formation occurs under physiological conditions near synthetic or biological hydrophilic-hydrophobic interfaces. This seems to require a heme dimer acting as a precursor of Hz crystals ...

WO cases of genetic linkage have been established in pigs. The C and J bloodgroup loci are closely linked (ANDRESEN and BAKER 1964; RASMUSEN 1965; ANDRESEN 1966a), and IMLAH (1965) has detected a close linkage between the H p locus for hematin-binding serum proteins (KRISTJANSSON 1961 ; HESSELHOLT 1963b) and the K blood-group locus. This report deals with additional information about the linkag...
