Find Protein Extinction Coefficient - Calculator

The determination of protein concentration via spectrophotometry frequently relies on a mathematical tool that predicts the absorbance of a protein solution at a specific wavelength. This tool leverages a protein’s amino acid sequence and the inherent light absorption properties of its constituent aromatic amino acids (tryptophan, tyrosine, and cysteine) to estimate its extinction coefficient. This calculated value, along with the measured absorbance, allows for the application of the Beer-Lambert Law, yielding a quantitative assessment of the protein concentration in a solution. For example, if a solution containing a protein with a known extinction coefficient of 1.0 (cm^-1M^-1) exhibits an absorbance of 0.5 at a 280 nm wavelength in a 1 cm pathlength cuvette, its concentration is calculated to be 0.5 M.

Pearson Correlation & R: Calculate on Chegg + Tips

Pearson correlation assesses the strength and direction of a linear relationship between two variables. The coefficient of determination, often denoted as R-squared, quantifies the proportion of variance in one variable that is predictable from the other. A common resource for understanding and applying these statistical measures is Chegg, which provides explanations and solutions related to their calculation.

These statistical tools are crucial across various disciplines, including economics, psychology, and engineering, for identifying and quantifying relationships between variables. Understanding the linear association between data points provides valuable insights for prediction and informed decision-making. Historically, the Pearson correlation coefficient was developed by Karl Pearson in the late 19th century and has since become a foundational concept in statistical analysis.
