partial purification and characterization of gastrothylax crumenifer somatic antigens.the soluble extracts of gastrothylax crumenifer isolated from the rumen of buffalo (bubalus bubalis) were fractionated on a sephadex g-200 column. a total of eight major fractions (f1, f2, f3, f4, f5, f6, f7, and f8) were separated from the whole homogenate of g. crumenifer, and each of these fractions was tested for their antigenicity by elisa against rabbit hyperimmune sera. it was observed that f1, f2, f3 and f4 were highly antigenic, f6 and f7 were moderately antigenic and f5 and f8 were poo ...200010729642
modulation of the oxygen affinity of cobalt-porphyrin by globin.we have combined two extreme effects which influence the oxygen affinity to obtain a cobalt-based oxygen carrier with an affinity similar to that of human adult hemoglobin (hba). the goal was to obtain an oxygen transporter with a lower oxidation rate. exchange of the heme group (fe-protoporphyrin ix) in hb with a cobalt-porphyrin leads to a reduction in oxygen affinity by over a factor of 10, an oxygen affinity too low for use as a blood substitute. at the other extreme, certain globin sequence ...200010788615
