What does quantification of proteins mean?
Protein quantification or total protein content by colorimetric methods such as absorbance at 280, Bradford or BCA assays and quantitative amino acid analysis. Protein quantification is necessary to understand the total protein content in a sample or in a formulated product.
What are the methods of protein quantification?
Individual protein quantitation methods include enzyme-linked immunosorbent assay (ELISA) assay, western blot analysis, and more recently, mass spectrometry, among others. In certain cases trade group regulations or laws may require specific methods for protein quantitation.
Why is determining protein concentration important?
Determining the protein concentration in your sample is an important step in any laboratory workflow that involves protein extraction and/or analysis. Knowing how much protein you have can help you compare results from one protein to another and from one experiment to the next.
Why different cells have different concentration of proteins?
All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and, consequently, it contains a particular set of proteins that determine its function.
What is the meaning of quantitation?
Definition of quantitate transitive verb. 1 : to measure or estimate the quantity of especially : to measure or determine precisely. 2 : to express in quantitative terms.

Why is BSA used as a protein standard?
BSA is used because of its stability to increase signal in assays, its lack of effect in many biochemical reactions, and its low cost, since large quantities of it can be readily purified from bovine blood, a byproduct of the cattle industry.
Why is it important to determine protein concentration?
What are protein concentrations used for?
The measurement of protein concentration in an aqueous sample is an important assay in biochemistry research and development labs for applications ranging from enzymatic studies to providing data for biopharmaceutical lot release.
What is difference between quantitation and quantitation?
As verbs the difference between quantify and quantitate is that quantify is to assign a quantity to while quantitate is to measure the quantity of especially with high accuracy and including measurement uncertainty, as in quantitative analysis.
Is quantitation a real word?
verb (used with object), quan·ti·tat·ed, quan·ti·tat·ing. to determine thequantity of, especially with precision.
