[Isoelectric behavior of oxyhemoglobin]

K Winnefeld, E Klotzmann, R Schmidt

    Acta Biologica Et Medica Germanica
    |January 1, 1981
    PubMed
    Summary

    Isoelectric point of oxy-hemoglobin shifts to lower pH with increased ionic strength. Its behavior also varies across different buffer systems, impacting hemoglobin analysis.

    Area of Science:

    • Biochemistry
    • Protein Chemistry

    Context:

    • Hemoglobin's isoelectric behavior is crucial for understanding its properties.
    • Ionic strength and buffer systems are key factors influencing protein charge.

    Purpose:

    • To investigate how ionic strength and buffer systems affect the isoelectric point of oxy-hemoglobin.
    • To characterize the isoelectric function of oxy-hemoglobin under varying conditions.

    Summary:

    • Increasing ionic strength causes a shift in the isoelectric point of oxy-hemoglobin towards lower pH values.
    • The isoelectric function of oxy-hemoglobin demonstrates variability when examined in different buffer systems.
    • These findings highlight the complex interplay between environmental factors and hemoglobin's charge characteristics.

    Impact:

    • Provides essential data for optimizing hemoglobin separation and purification techniques.
    • Enhances understanding of hemoglobin's behavior in diverse biological and experimental settings.
    • Contributes to the accurate interpretation of hemoglobin analysis in clinical and research applications.
