Improved separation of fetal hemoglobin by mini-column chromatography.
نویسندگان
چکیده
We present chromatographic conditions for separating and measuring fetal hemoglobin on a 5-cm column of Sephadex CM-50. A distinct fetal band is evident, even when present at less than 1% of total hemoglobin. Precision (CV) of better than 5% is achievable.

Postnatal Fetal and Adult Hemoglobin Synthesis in D Trisomy Syndrome
Studies were carried out during the neonatal period in three infants with D1 trisomy syndrome to measure the proportion of fetal and adult hemoglobin being synthesized. These values were compared on the one hand to those previously reported from samples obtained from cord blood of normal newborn infants ranging from 25 to 43 wk gestation, and on the other hand to those values determined in crit...

A B S T R A C T To determine if environmental factors could effect the switchover from fetal hemoglobin (HbF) to adult hemoglobin (HbA) synthesis, studies were carried out on blood samples from eight infants born at <1,000 g, when they had reached their postconceptional age corresponding to term. All of these infants required prolonged intensive care, multiple blood transfusions, and two requir...
متن کاملSeparation of Somatropin and Its Degradation Products by High-Performance Liquid Chromatography Using a Reversed-Phase Polymeric Column
The accurate prediction of protein stability is one of the most challenging goals in protein formulation and delivery. In this study, a gradient RP-HPLC method is described for the separation of human growth hormone (hGH) variants as deamidated and oxidized forms. The methodology employed a polymeric poly (styrene-co-divinylbenzene) column and a 1mL/min flow rate of a linear gradient of 0.1% v/...
متن کاملThe Comparison of Silica Gel-Alumina Sorbents for Separation of PAHs and PCBs
The aim of this research is to develop a silica gel and alumina column chromatography for separation of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) into two groups. This is achieved by optimizing the cut-off volume of eluting solvent and weight ratio of silica gel and alumina. In this process mixture of PAHs and PCBs divide in two groups and simultaneously o...
