When considering PEGylation for a protein drug, how do you decide what PEGylation chemistry to use?

The core question in targeted protein degradation is: “Can the cell be made to remove this protein, and can the removal process be proven to follow the expected mechanism?” Cellular protein levels are jointly regulated by synthesis, folding, localization, and degradation. The two systems ...

Streptavidin is a bacterial protein that binds the small molecule biotin with exceptionally high affinity. The streptavidin–biotin pair represents one of the strongest noncovalent interactions known. Streptavidin agarose beads take advantage of this interaction as a solid-phase platform to ...

After proteins are separated by SDS-PAGE or related gels, staining is used for visualization, rough quantification, and purity assessment.
