Keterangan
LAIR1 is an approximately 40 kDa type I transmembrane inhibitory glycoprotein belonging to the Ig superfamily. Mature human LAIR1 is a 266 amino acid (aa) type I transmembrane protein that includes a 144 aa extracellular domain (ECD) with one collagen-binding C2-type Ig-like domain, and a 101 aa cytoplasmic domain with two ITIM motifs. Human LAIR1 ECD shares <45% aa sequence identity with mouse, rat, bovine or canine LAIR1 ECD, but all are functional orthologs. LAIR1 functions as an inhibitory receptor that plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells, B-cells and T-cells. Activation by Tyr phosphorylation results in recruitment and activation of the phosphatases PTPN6 and PTPN11. It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation.

Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended (usually we use 1mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
Storage
Transported with ice packs. Store at -20℃ to -80℃, valid for one year.
After reconstitution, store unopened at -20 to -80°C for 3 to 6 months. After reconstitution, store at 2 to 8°C for 2 to 7 days.
It is recommended to store in aliquots and freeze for the first use to avoid repeated freezing and thawing.
