Horse and Fowl Hæmoglobin

Abstract

DURING the course of a spectrographic examination of horse and fowl hæmoglobin, we have noted that the absorption band having its peak at 4100 A. for oxyhæmoglobin and 4300 A. for hæmoglobin in solutions of the above compounds, does not appear when washed corpuscle suspensions containing hæmoglobin and oxyhæmoglobin in similar concentrations are examined. Furthermore, the absorption which begins at 2500 A. in solutions of horse hæmoglobin also is absent when hæmoglobin or oxyhæmoglobin is observed in washed cell suspensions. The specific bands in the visible regions of solutions of the above pigments are observed in the washed cell suspensions in their usual location.
