分子别名（Synonym）
TL1A, VEGI, TNFSF15
表达区间及表达系统（Source）
Human TL1A Protein, Fc Tag (TLA-H5263) is expressed from human 293 cells (HEK293). It contains AA Val 84 - Leu 251 (Accession # O95150-1).
Predicted N-terminus: Pro
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 85.1 kDa. The protein migrates as 95-110 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度（Purity）
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
