Explain in brief the basic principle of protein quantification using (i) Bradford (ii) Lowry (iii) Biuret methods
Most of protein quantification methods rely on the changes of protein solution after reacted with specific reagent and the changes are able to measured using spectrophotometry. What’s the difference between concept of absorbance and transmittance in spectrophotometry and is there any correlation between both parameters?
What’s the function of standard curve in a protein quantification experiment!
