WebA description is given of the nature of column packings for reverse phase high performance liquid chromatography (HPLC) and of the equipment that is available for HPLC procedures. HPLC methods have been applied to the identification of abnormal hemoglobins. In most instances, the variant peptide(s) is easily detected on the chromatogram. The effect of … WebHemoglobin with decreased affinity for oxygen increases the oxygenation of tissues, because it gives up oxygen more easily during microcirculation. In foetal circulation, however, at a partial oxygen pressure (pO2) of 25 mmHg in the umbilical vein, the oxygen carrier is type F hemoglobin which has a high oxygen affinity.
