FITC-Labeled Human B7-H3 (4Ig), Fc Tag (B7B-HF2F4) is expressed from human 293 cells (HEK293). It contains AA Gly 27 - Thr 461 (Accession # Q5ZPR3-1). It is the FITC labeled form of Human B7-H3 (4Ig), Fc Tag (Cat. No. B7B-H5258).

FITC

Excitation source: 488 nm spectral line, argon-ion laser

Excitation Wavelength: 488 nm

Emission Wavelength: 535 nm

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

The FITC to protein molar ratio is 1-3.

>90% as determined by SDS-PAGE.

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