How is a standard curve constructed

WebProtein Standard Curve Version 6-18-12 • Standard curves are used in many assays in biotechnology. • The idea involves making a series of standard solutions that are then assayed for their value. These values can be used to generate a graph, which can then be used to determine the concentration of unknown protein samples. WebA standard curve, also known as a calibration curve, is a type of graph used as a quantitative research technique. Multiple samples with known properties are measured and graphed, which then allows the same properties to be determined for unknown samples by interpolation on the graph.
