Welcome to the Bio-Rad Library of Variants - a compendium of HPLC cases.
This Digital Library contains case reports of variants hemoglobin provided by a select group of reference centers belonging to the worldwide community of laboratories actively working on diagnosis and prevention of sickle cell, thalassemia and other hemoglobinopathies.
