Active Recombinant Human MSLN Protein (Glu 296 - Gly 580), Fc-tagged, FITC-Labeled

• Cat.No.: MSLN-316H
• Product Overview: Recombinant Human MSLN Protein, Fc-tagged, FITC-Labeled is expressed from human HEK293 cells. It contains AA Glu 296 - Gly 580 (Accession # AAH09272.1). It is the FITC labeled form of Human Mesothelin (296-580), Fc Tag. Predicted N-terminus: Glu 296. This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 58.6 kDa. The protein migrates as 60-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. Conjugate (FITC): Excitation source: 488 nm spectral line, argon-ion laser; Excitation Wavelength: 488 nm; Emission Wavelength: 535 nm. The FITC to protein molar ratio is 1-2.5. 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.
