How does oxygen bind to hemoglobin? Hemoglobin , or Hb, is a protein molecule found in red blood cells erythrocytes made of four subunits: two alpha subunits and two beta subunits.

Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Leyla Yitkin Teacher. How do you measure hemoglobin concentration?

To measure the hemoglobin concentration , a lysing agent is added to a sample of diluted blood; the lysing agent disrupts all the red blood cells in the sample and releases the hemoglobin into the fluid so that the sample then consists of a solution of hemoglobin.

Save time! Potassium ferricyanide transforms hemoglobin into methemoglobin, and methemoglobin combines with potassium cyanide to produce hemiglobincyanide cyanmethemoglobin. This method is optional for the estimation of hemoglobin and this method is recommended by the International Committee for Standardization in hemotology.

This is because in this method all type of hemoglobin is transformed to cyanmethemoglobin except sulfhemoglobin , and a firm and trustworthy standard is available.

This way all types of hemoglobin present in the blood are entirely transformed into a single compound cyanmethemoglobin. When the reaction is entire, the absorbance of the solution is deliberate in a spectrophotometer at nanometers. Can drabkins reaction work with freeze dried hemoglobin instead?

I think if you thaw the frozen Hb, then try with control. That may work. Leyal Reply. Han Reply. Maryam Ch Reply. I have described the procedure.
