Haemoglobin a1c

(Science: haematology) The substance of red blood cells that carries oxygen to the cells and sometimes joins with glucose.

Because the glucose stays attached for the life of the cell (about 4 months), a test to measure haemoglobin a1c shows what the persons average blood glucose level was for that period of time.

... sample and then used a pH and of 9 and collected sample 2. So now I have to comment on the charge properties and likely pI's of (cytochrome C and haemoglobin).. CM contains a negative charge right? So that means in order for those 2 proteins to bind to it they both proteins must contain a positive ...
