Protein tags are peptide sequences genetically grafted onto a recombinant protein. Tags are attached to proteins for various purposes. They can be added to either end of the target protein, so they are either C-terminus or N-terminus specific or are both C-terminus and N-terminus specific. Some tags are also inserted at sites within the protein of interest; they are known as internal tags.
Bovine pancreatic ribonuclease, also often referred to as bovine pancreatic ribonuclease A or simply RNase A, is a pancreatic ribonuclease enzyme that cleaves single-stranded RNA. Bovine pancreatic ribonuclease is one of the classic model systems of protein science. Two Nobel Prizes in Chemistry have been awarded in recognition of work on bovine pancreatic ribonuclease: in 1972, the Prize was awarded to Christian Anfinsen for his work on protein folding and to Stanford Moore and William Stein for their work on the relationship between the protein's structure and its chemical mechanism; in 1984, the Prize was awarded to Robert Bruce Merrifield for development of chemical synthesis of proteins.

Laura Lee Kiessling is an American chemist and the Novartis Professor of Chemistry at the Massachusetts Institute of Technology. Kiessling's research focuses on elucidating and exploiting interactions on the cell surface, especially those mediated by proteins binding to carbohydrates. Multivalent protein-carbohydrate interactions play roles in cell-cell recognition and signal transduction. Understanding and manipulating these interactions provides tools to study biological processes and design therapeutic treatments. Kiessling's interdisciplinary research combines organic synthesis, polymer chemistry, structural biology, and molecular and cell biology.

Bradley Lether Pentelute is currently a professor of chemistry at the Massachusetts Institute of Technology (MIT). His research program lies at the intersection of chemistry and biology and develops bioconjugation strategies, cytosolic delivery platforms, and rapid flow synthesis technologies to optimize the production, achieve site-specific modification, enhance stability, and modulate function of a variety of bioactive agents. His laboratory successfully modified proteins via cysteine-containing “pi-clamps” made up of a short sequence of amino acids, and delivered large biomolecules, such as various proteins and drugs, into cells via the anthrax delivery vehicle. Pentelute has also made several key contributions to automated synthesis technologies in flow. These advances includes the invention of the world's fastest polypeptide synthesizer. This system is able to form amide bonds at a more efficient rate than standard commercial equipment and has helped in the process of understanding protein folding and its mechanisms. This automated flow technology was recently used to achieve total chemical synthesis of protein chains up to 164 amino acids in length that retained the structure and function of native variants obtained by recombinant expression. The primary goal of his endeavor is to use these processes to create designer biologics that can be used to treat diseases and solve the manufacturing problem for on-demand personalized therapies, such as cancer vaccines.

A collagen hybridizing peptide (CHP) is a synthetic peptide sequence with typically 6 to 10 repeating units of the Gly-Xaa-Yaa amino acid triplet, which mimics the hallmark sequence of natural collagens. A CHP peptide usually possesses a high content of proline and hydroxyproline in the Xaa and Yaa positions, which confers it a strong propensity to form the collagen's unique triple helix conformation. In the single-stranded (monomeric) status, the peptide can recognize denatured collagen strands in tissues by forming a hybridized triple helix with the collagen strands. This occurs via the triple helical chain assembly and inter-chain hydrogen bonding, in a manner similar to primers binding to melted DNA strands during PCR. The binding does not depend on a specific sequence or epitope on collagen, enabling CHPs to target denatured collagen chains of different types.
