b'Detect, measure, and analyzeprotein expression, identity, and function using our portfolio of protein biology products.Protein biology encompasses both the study of the structure and function of proteins as the primary focus of investigation and the use of antibodies, proteins, and peptides as tools to purify, detect, and characterize biological systems. Certain methods of protein analysis, such as immunoprecipitation, western blotting, and ELISA, have been used routinely in laboratories for many years. Others, such as quantitative protein mass spectrometry and cryo-EM, are relatively recent and rapidly developing technologies. New tools and products are continually being developed to advance all aspects of protein biology research.'
