- SynonymLAIR2,CD306
- SourceBiotinylated Human LAIR-2, His,Avitag (LA2-H82E4) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Pro 152 (Accession # Q6ISS4-1).Predicted N-terminus: Gln 22Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.
The protein has a calculated MW of 17.8 kDa. The protein migrates as 25-28 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- BiotinylationBiotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
- Biotin:Protein RatioThe biotin to protein ratio is 0.5-1 as determined by the HABA assay.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by reduced SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Biotinylated Human LAIR-2, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human Collagen I protein at 2 μg/mL (100 μL/well) can bind Biotinylated Human LAIR-2, His,Avitag (Cat. No. LA2-H82E4) with a linear range of 2-78 ng/mL (QC tested).
- BackgroundLeukocyte-associated immunoglobulin-like receptor 2 (LAIR2) is also known as CD antigen CD306. LAIR2 contains one Ig-like C2-type (immunoglobulin-like) domain. LAIR2 is a member of the immunoglobulin superfamily and was identified by its similarity to LAIR1, an inhibitory receptor present on mononuclear leukocytes. LAIR2 / CD306 is thought to be secreted and may help modulate mucosal tolerance.
