Application

Atto labels are designed for highest sensitivity applications. A unique combination of advantages makes them highly favorable tools for all kinds of labeling applications. And some of their properties make them specifically interesting for single molecule detection. Atto labels are based on rigid structures and do not show any cis-trans-isomerization, which lowers brightness of signals and leads to environment dependency, e.g., spectral shifts by conjugation.
Atto 610 shows an molar extinction of 110,000 and QY of 70% in water (70% in ethanol). Decay time is 3.3 ns.

Serpins inhibit serine proteases by mechanically disrupting the protease active site. The protease first reacts with the serpin's reactive center loop (RCL) to form an acylenzyme. Then the RCL inserts into a beta-sheet in the body of the serpin, translocating

A simple and effective protocol for detections of protein-protein and protein-small molecule interactions has been developed. After interactions between proteins and their corresponding ligands, we employed colloidal silver staining for producing active substrates for surface-enhanced Raman scattering (SERS) and surface-enhanced

Serpins regulate serine proteases by forming metastable covalent complexes with their targets. The protease docks with the serpin and cleaves the serpin's reactive center loop (RCL) forming an acylenzyme intermediate. Cleavage triggers insertion of the RCL into beta sheet A
