  2. Thermal shift assay - Wikipedia

    en.wikipedia.org/wiki/Thermal_Shift_Assay

    Size exclusion chromatography can be used directly to access protein stability in the presence or absence of ligands. [31] Samples of purified protein are heated in a water bath or thermocycler, cooled, centrifuged to remove aggregated proteins, and run on an analytical HPLC. As the melting temperature is reached and protein precipitates or ...

  3. Protein detection - Wikipedia

    en.wikipedia.org/wiki/Protein_detection

    Protein detection technique has been utilized to discover protein in different category food, such as soybean (bean), walnut (nut), and beef (meat). [4] Protein detection method for different type food vary on the basis of property of food for bean, nut and meat. Protein detection has different application in different field.

  4. Pierce Protein Assay - Wikipedia

    en.wikipedia.org/wiki/Pierce_Protein_Assay

    This method is able to detect as low as 25 μg/ml and up to 2000 μg/ml of protein in a 65 ul sample, using standard protocol. This method may be preferred for samples containing detergents or other reducing agents. This method has a fast detection speed and low protein-to-protein variability in comparison to the BCA or Coomassie (Bradford ...

  5. Protein methods - Wikipedia

    en.wikipedia.org/wiki/Protein_methods

    Protein methods are the techniques used to study proteins. There are experimental methods for studying proteins (e.g., for detecting proteins, for isolating and purifying proteins, and for characterizing the structure and function of proteins, [1] often requiring that the protein first be purified). Computational methods typically use computer ...

  6. Cycloheximide chase - Wikipedia

    en.wikipedia.org/wiki/Cycloheximide_chase

    Cycloheximide chases are also valuable for assessing how different mutations affect the stability of a protein. Experiments have been conducted in yeast and mammalian cells to determine the critical residues required for protein stability and how disease-associated mutations may be affecting protein half-lives within the cell.

  7. Bradford protein assay - Wikipedia

    en.wikipedia.org/wiki/Bradford_protein_assay

    The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution. The reaction is dependent on the amino acid composition of the measured proteins.

  8. Equilibrium unfolding - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_unfolding

    where is the stability of the protein in water and [D] is the denaturant concentration. Thus the analysis of denaturation data with this model requires 7 parameters: Δ G w {\displaystyle \Delta G_{w}} , Δ n {\displaystyle \Delta n} , k , and the slopes and intercepts of the folded and unfolded state baselines.

  9. Bicinchoninic acid assay - Wikipedia

    en.wikipedia.org/wiki/Bicinchoninic_acid_assay

    BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
