Antibodies Served With a Side of Phospho-Specificity

Anyone who is remotely interested in biology, or has perhaps scrolled through fitness websites to get in shape, has come across the word "protein". There is, however, much more to proteins than simply being a key player in maintaining active lifestyles. Proteins are ubiquitous in the cells of the body and are the driving force for key cellular processes. In order for proteins to carry out their duties, they need to be well-armed to execute their functions. This process of making the protein competent is achieved through specific post translational modifications (PTMs). The star of the PTMs is a cellular process called phosphorylation. The conventional methods adopted for quantifying phosphorylation are highly labor intensive. The development of phospho-specific antibodies has allowed for a huge sigh of relief from researchers due to their reputation of being quick, and detecting only phosphorylated forms of proteins in a complex mixture of phosphorylated and non-phosphorylated forms.
