However, in heterogeneous cell populations, such as tumors or differentiating stem cells, cellular decisions are controlled by hundreds, even thousands of proteins acting in concert characterizing such complex systems demands measurements of thousands of proteins across thousands of single cells. The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology in order to study proteins we must first know how to separate then quantify the amount using basic principles of experimental design such as a standard. These proteins include keratin intermediate filaments (kifs) and keratin-associated proteins (kaps) that together form a matrix held together through disulfide, hydrogen, electrostatic, and amide bonds.
