Predict the changes in specific activity (ex. increases, decreases) and concentration of your protein as a percent of total protein in the sample from beginning (cell lysate) to the end of a protein purification scheme.
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.

Protein purification is a set of procedures designed to separate one or more proteins from a complex mixture, typically cells, tissues, or entire organisms. Protein purification is essential for determining the function, structure, and interactions of a protein of interest. The purification process may separate the mixture's protein and non-protein components, and then separate the desired protein from all other proteins. The most time-consuming aspect of protein purification is typically the separation of one protein from all others. Separation procedures typically take advantage of differences in protein size, physicochemical properties, binding affinity, and biological activity.
