Fig. 2From: Age-Markers on the Red Blood Cell Surface and Erythrocyte Microparticles may Constitute a Multi-parametric Strategy for Detection of Autologous Blood TransfusionChanges of Band 3 (protein and/or complex) and of GYPA concentrations as a function of storage time. a Band 3 levels measured by flow cytofluorimetry; b Band 3 levels measured by western immunoblotting assay; c Band 3 complex levels measured by flow cytofluorimetry analysis, using Eosin-5’-maleimide dye, which binds the whole macro-complex and not only the single protein. d Band 3 protein levels measured by western immunoblotting assay in RBCs fractions isolated by Percoll density gradients; e GYPA levels measured by flow cytofluorimetry f GYPA/Band 3, both measured by flow cytofluorimetryBack to article page
