title: An improved microchromatographic procedure for separating HbA2 from HbS for the purpose of quantitation.
abstract: A microchromatographic method for separating hemoglobin A2 from hemoglobin S and their subsequent quantitation on DEAE-cellulose has been improved. The new procedure is more versatile, since the same system can be used when hemoglobin S is present or absent in the sample without changing to a longer column or another buffer system. Also, the technic is less sensitive to small changes in pH of buffers or resin than are other procedures.
