FITC-Labeled Human BAFF, Fc Tag is expressed from human HEK293 cells. It contains AA Ala 134 - Leu 285 (Accession # AAH20674.1). It is the FITC labeled form of Human BAFF, Fc Tag. Excitation source: 488 nm spectral line, argon-ion laser. Excitation Wavelength: 494 nm; Emission Wavelength: 518 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 seive treatment during purification process. The FITC to protein molar ratio is 1.5-3.
