表达区间及表达系统（Source）
Human VCAM-1 Protein, Fc Tag, premium grade (VC1-H5253) is expressed from human 293 cells (HEK293). It contains AA Phe 25 - Glu 698 (Accession # P19320-1).
Predicted N-terminus: Phe 25
It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage.
GMP-VC1H25 is the GMP version of this VC1-H5253. These two proteins display indistinguishable performance profiles, thereby ensuring a seamless transition for end users from early preclinical stag to later clinical phases.Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 100.7 kDa. The protein migrates as 126 kDa±5 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
