摘要: Separation of adult rat bone marrow cells by the method thin layer countercurrent distribution permits analyses 59Fe-tagged erythroid for various multiple hemoglobins and assignment such to at different stages their development. Of six red cell hemoglobins, hemoglobin 5 is synthesized most actively in earliest whereas 4 (the major cell) latest cells, e.g. reticulocyte. Experimental evidence also indicates that maturation accompanied a decreased rate synthesis 5. The contain two 7 8, which are absent cell. Similar studies with guinea pig confirm nonuniform biosynthesis its suggest phenomenon may be general one among mammalian hemoglobins.
