TL1A, VEGI, TNFSF15
表达区间及表达系统（Source）
Human TL1A, His Tag (TLA-H5243) is expressed from human 293 cells (HEK293). It contains AA Leu 72- Leu 251 (Accession # O95150-1).
Predicted N-terminus: His
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 22.4 kDa. The protein migrates as 26 kDa and 28-30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
