Alteration of Electrophoretic Mobility of Hemoglobin in Bloodstains
Phenotyping of hemoglobin variants from whole blood and dried bloodstains is an important procedure for the forensic scientist. Although electrophoretic techniques for hemoglobin phenotyping have been described [1–5], there has been to our knowledge no published report of alterations in the electrophoretic mobility of hemoglobin in dried bloodstains. In the present study, observations were made on changes after electrophoresis on cellulose acetate membranes in the mobility of hemoglobin from bloodstains 1 to 28 days old. A procedure has been worked out to prevent these changes which may cause errors in the phenotyping of hemoglobin variants.
