• Cat.No.: FCER1A-1460H
• Product Overview: Recombinant Human FCER1A protein(Val26-Leu204), fused with Fc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 26-204 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.
• Bio-activity: Loaded Human Fc epsilon RI alpha, Fc Tag on AHC Biosensor, can bind Immunoglobulin E, Human Plasma with an affinity constant of 0.07 nM as determined in BLI assay (ForteBio Octet Red96e).
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminusThe protein has a calculated MW of 47.3 kDa. The protein migrates as 55-85 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
