Biochemistry - ACSHaptoglobin (Hp) binds free hemoglobin (Hb) dimers to prevent negative consequences of Hb circulation in the extracellular environment. Although both monomeric Hb and myoglobin (Mb) species also present potential risks, their interactions with Hp have not been extensively studied. Mb is homologous to both the α- and β-chains of Hb and shares many conserved Hb/Hp interface residues, yet whether Hp binds Mb remains unclear…Hb α- and β-chains were separated via reversed phase high-performance liquid chromatography…using a 4.6 mm × 150 mm C8 [O-5-100/15] analytical column with a 5 µm pore size (Separation Methods Technologies, Newark, DE)… READ MORE HERE
