Scenario: First, 0.1 mL of the unknown is mixed with 0.1 mL of distilled water. Then, 0.1 mL of the solution and 0.9 mL of distilled water are mixed in a cuvette and the absorbance is measured at 410 nm. Given the absorbance, molecular mass and the extinction coefficient of the unknown are 0.650, 16950 g and 188 mM-1cm-1 respectively, and the path length is 1 cm, how can I find the original concentration of the unknown in mg/mL by Beer-Lambert Law (NOT molarity M)?
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
