Human CEACAM-5 Protein, His Tag AIDD-Ready protein is designed for direct use in SPR assays. It is supplied in a sugar-free, glycerol-free formulation to eliminate refractive index interference in SPR. No desalting or buffer exchange is required before use, simplifying the SPR workflow and supporting high-throughput experimental validation to accelerate the transition from AI prediction to wet-lab validation.
CEACAM-5, CD66e, CEA, Meconium antigen 100
Human CEACAM-5 Protein, His Tag (CE5-H5226AI) is expressed from human 293 cells (HEK293). It contains AA Lys 35 - Ala 685 (Accession # P06731).
Predicted N-terminus: Lys 35

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 72.2 kDa. The protein migrates as 95-180 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a dimer.
>95% as determined by SDS-PAGE.
