The phosphate buffer only plays a minor role in the blood, however, because H 3 PO 4 and H 2 PO 4 – are found in very low concentration in the blood. Hemoglobin also acts as a pH buffer in the blood.
WebApr 11, 2024 · An aliquot of 10 ml blood was centrifuged for 10 min at 2000×g to obtain erythrocytes. Supernatant and the thin layer of leukocytes were discarded, and the erythrocyte pellet was washed twice in isotonic buffer A (5 mM NaH 2 PO 4, 150 mM NaCl, 2 mM Mg(OAc) 2, pH 7.5). WebA buffer is an aqueous solution that resists changes in pH when acids or bases are added to it. A buffer solution is typically composed of a weak acid and its conjugate base. There are three major buffer systems that are responsible for regulating blood pH: the bicarbonate buffer system, the phosphate buffer system, and the plasma protein ...
