Serum albumin can be quantitated by all methods except
A. Binding by bromcresol green
B. Electrophoresis at pH 8.6
C. Immunonephelometry
D. Sulfosalicylic acid precipitation
Option c)Sulfosalicylic acid Precipitaion.
Three of the popular methods available for measuring serum albumin are serum protein electrophoresis and the two dye binding methods: Brom Cresol Green and Brom Cresol Purple.
Also immunonephelometry is a technique used in immunology to determine the levels of several blood plasma proteins including Albumin.
But Sulfosalicylic acid precipitation test can be used only to Quantify Urea Albumin level and Not Serum Albumin.

You are to purify a highly soluble homotetrameric protein containing a NADP binding site, in its functional form, and a pI = 9 with a subunit molecular weight of 35,000 Da from a crude extract of E. coli. For this protein, select the four best techniques from the list below and place them in the correct order for the most reasonable strategy to obtain homogeneous protein. (A) Precipitation of proteins using high ionic strength (40%) ammonium sulfate, followed by a...
Gel electrophoresis. Polypeptides can be separated by electrophoresis according to their relative content of acidic and basic residues. The isoelectric point (pI) of a polypeptide is the pH at which its net charge is zero. (See Fig 3.11 of your textbook). A) At physiological pH (= 7.4), what is the net charge on the tripeptide Asp-Arg-Glu-His? B) Calculate the pI of this tetrapeptide. [Hint: Using the pK, values in Table 2.1 and the Henderson-Hasselbalch equation, determine the pH when the...
