A 20µL unknown protein was mixed with 80µL of water. Then, 10µL of this mixture was added with 10µL Bradford reagent and diluted with water to a total volume of 100µL. The absorbance at 595 nm shows 0.08 units. Solve for the protein concentration (in mg/mL) of the original unknown protein. How much protein (in mg) is in the 20uL sample? Express your answer in 3 significant figures.
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.
