Human TREM-1 / CD354 Protein, Fc Tag
Synonym
TREM1, CD354
Source
Human TREM-1, Fc Tag (TR1-H5251) is expressed from human 293 cells (HEK293). It contains AA Ala 21 - Arg 200 (Accession # Q9NP99-1).
Predicted N-terminus: Ala 21
Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 46.7 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
Triggering receptor expressed on myeloid cells 1 (TREM1) is also known as CD antigen CD354, and is a type I transmembrane protein with a single Ig-like domain. TREM1 is highly expressed in adult liver, lung and spleen than in corresponding fetal tissue. TREM-1 / CD354 stimulates neutrophil and monocyte-mediated inflammatory responses, and also triggers release of pro-inflammatory chemokines and cytokines, as well as increased surface expression of cell activation markers. Amplifier of inflammatory responses that are triggered by bacterial and fungal infections and is a crucial mediator of septic shock. TREM1 can interacts with TYROBP / DAP12.
