Streptavidin Protein-Cy5

Streptavidin, SA

Streptavidin Protein-Cy5 (STN-NC113) is expressed from E. coli cells.

Cy5

Excitation Wavelength: 651 nm

Emission Wavelength: 670 nm

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with Cy5 using standard chemical labeling method. The residual Cy5 is removed by molecular sieve treatment during purification process.

>90% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
