Other Tags and Version Biotin & Other Labeled Version
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 40.4 kDa. The protein migrates as 52-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

FAQ
- Product
Why are different expression ranges (31–134 and 31–150) used for human BTLA proteins?
The different lengths of human BTLA proteins correspond to different isoforms. The aa31–134 sequence represents isoform 2, while aa31–150 corresponds to isoform 1. ACRO provides BTLA proteins of varying lengths to meet diverse customer requirements.
