Select the principle on which the method for determining the following proteins is based.
Identify the protein:
microprotein with a molecular weight of , produced mainly by myeloid and lymphoid cells, plasma concentration about 1-2 mg/L
tumour marker, rises with a decrease in glomerular filtration
Identify the protein:
glycoprotein produced by the liver, α2β2 tetramer, acute phase reactant, plasma concentration about 1 g/L
it binds very tightly to the hemoglobin molecule, the resulting complex does not pass through the glomerulus, it is quickly absorbed by RES cells
