Estimation of Protein
Proteins in serum react with copper of Biuret Reagent in alkaline medium to form a blue purple complex with absorption maximum at 550 nm. Sample: Serum or plasma. Reagents:
Mark three test tubes as Blank, Standard and Test and proceed as follows:
Calculations : Total Proteins (g/dL) (X) = OD of (T) ------------- x 6 OD of (S) Globulins (g/dL) = (Total protein ) – (Albumin)
A/G Ratio = (Albumin) ----------------------------- (Total Protein) – (Albumin) /font>/font>Method of Estimation : Biuret Method |
