详细说明
- Purity>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
- Endotoxin Level<0.10 EU per 1 μg of the protein by the LAL method.
- ActivityMeasured by the ability of the immobilized protein to support the adhesion of HT‑29 human colon adenocarcinoma cells. When 5 x 10 4 cells/well are added to rhLAIR-2 coated plates (50 µg/mL with
100 µL/well), approximately 40%-60% will adhere after 10 minutes at 37° C.
Optimal concentration depends on cell type as well as the application or research objectives. - SourceMouse myeloma cell line, NS0-derived Gln22-Pro152, with a C-terminal 6-His tag

LAIR-2 (leukocyte-associated Ig-like receptor-2; CD306) is a secreted, 131 amino acid (aa) protein that contains one Ig-like C2 type domain, making it a member of the Ig superfamily. When compared to LAIR-1, its transmembrane counterpart, it shares 83% aa identity across the signal sequence and extracellular domains; (1-3) although one is secreted and one is membrane-bound, the two LAIR proteins are thought to have arisen from a common gene ancestor and appear to share similar adhesion profiles. This suggests that LAIR-2 may compete with LAIR-1 for ligand binding (3, 4). A 114 aa alternate splice form of LAIR-2 is truncated at the C terminus, but retains the entire Ig domain (1-3). The expression profile of these splice forms, and the presence of orthologs in other species, have not been reported.
