4-1BB Ligand,TNFSF9,CD137L
表达区间及表达系统（Source）
Human 4-1BB Ligand (71-254) Protein, Fc Tag, premium grade (41L-H5269) is expressed from human 293 cells (HEK293). It contains AA Arg 71 - Glu 254 (Accession # P41273-1).
Predicted N-terminus: Pro
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-41LH26 is the GMP version of this 41L-H5269. 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 N-terminus.
The protein has a calculated MW of 87.5 kDa. The protein migrates as 95 kDa±5 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
