General description

This kit contains sufficient amounts of reactive dye, buffers and protein purification sets for performing five labeling reactions (1 mg protein each) and for the subsequent purification of the labeled protein.

Application

Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation. Atto 550, which is similar to Cy3, may be useful in applications such as fluorescence resonance energy transfer (FRET) and as a tag for molecules such as secondary antibodies. Atto 550 Protein Labeling Kit contains Atto 550 succinimidyl ester which enables conjugation of Atto 550 to the primary amino groups of the proteins and other molecules.

Patients with albuminuria and CKD frequently have vascular dysfunction but the underlying mechanisms remain unclear. Because the endothelial surface layer, a meshwork of surface-bound and loosely adherent glycosaminoglycans and proteoglycans, modulates vascular function, its loss could contribute to both renal
