Add vinegar and measure the protein precipitate. Mass of precipitate/mass of shake x100= % protein
A protein marker is a mixture of proteins of known sizes that is run alongside unknown samples in electrophoresis. It is used as a reference to help estimate the size of the unknown proteins based on their migration pattern in the gel. This allows researchers to determine the size of proteins in their samples and compare them to standards.
To determine the number of amino acids in your protein, you can use the average molecular weight of an amino acid which is about 110 Da (Daltons). By dividing the molecular weight of your protein (8.9 kD or 8900 Da) by the average weight of an amino acid (110 Da), you can estimate that your protein contains approximately 81 amino acids.
