Recombinant Human TREM-2/Triggering Receptor Expressed On Myeloid 2

Description :

Recombinant Human Triggering Receptor Expressed On Myeloid Cells 2 is produced by our Mammalian expression system and the target gene encoding His19-Ser174 is expressed with a 6His tag at the C-terminus.

Formulation :

Lyophilized from a 0.2 米m filtered solution of PBS, pH7.4.

Purity :

Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin :

Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

Reconstitution :

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 米g/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Storage :

Lyophilized protein should be stored at < -20～C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7～C for 2-7 days.Aliquots of reconstituted samples are stable at < -20～C for 3 months.

Background :

Triggering Receptor Expressed on Myeloid cells 2 (TREM2)is a 35 kDa type I transmembrane member of the TREM family and Ig superfamily. Mature human TREM2 consists of a 156 amino acid (aa) extracellular domain (ECD) with one V-type Ig-like domain, a 21 aa transmembrane (TM) domain, and a 35 aa cytoplasmic tail. Soluble forms of the TREM2 ECD are generated by alternative splicing or proteolytic cleavage, and the cytoplasmic domain can be liberated by gamma-Secretase mediated intramembrane cleavage. A positively charged lysine within the transmembrane segment allows association with the signal adapter protein, DAP12 and inhibition of macrophage activation. TREM2 is expressed on macrophages, immature myeloid dendritic cells, osteoclasts, microglia, and adipocytes.It promotes the differentiation and function of osteoclasts, the production of inflammatory cytokines by adipocytes, insulin resistance, and the phagocytic clearance of bacteria.
