Streptavidin Protein-Cy3

Streptavidin, SA

Streptavidin Protein-Cy3 (STN-NC114) is expressed from E. coli cells.

Predicted N-terminus: Met

Cy3

Excitation Wavelength: 555 nm

Emission Wavelength: 569 nm

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with Cy3 using standard chemical labeling method. The residual Cy3 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.
