Human IL-31 RA Protein, Fc Tag

• Catalog Number: orb570280
• Category: Proteins
• Description: Human IL-31 RA, Fc Tag is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Glu 519 (Accession # Q8NI17-1).
• Target: IL-31 RA
• Conjugation: Unconjugated
• Tag: C-Fc
• Reactivity: Human
• Form/Appearance: Powder
• Buffer/Preservatives: Tris with Glycine, Arginine and NaCl, pH 7.5
• Purity: 95%
• Protein Sequence: XP_011541444.1
• UniProt ID: Q8NI17
• MW: 83.5 kDa
• Application notes: This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 83.5 kDa. The protein migrates as 105-115 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
