Protein analysis

Protein analysis is the study and examination of proteins to understand their structure, function, and interactions. There are different methods to analyze proteins, such as surface plasmon resonance (SPR), bio-layer interferometry (BLI), enzyme-linked immunosorbent assay (ELISA), Western Blot, and flow cytometry (FACS).

Find out how SPR with Strep-Tactin®XT coated sensor chips enables directed, high-affinity immobilization that does not influence the activity of the ligand or require any modifications. Learn why the Strep-tag® is a reliable and time-saving alternative to Avi-tag and His-tag. 

Discover data showing why Strep-Tactin®XT is particularly useful for the quantification and kinetic characterization of Twin-Strep-tagged proteins using BLI.
