Biotinylated Human TREM2 Protein, His,Avitag™

Recommended Hot Products:

Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.

  • Synonym
    Triggering receptor expressed on myeloid cells 2,TREM2,TREM-2
  • Source
    Biotinylated Human TREM2, His,Avitag(TR2-H82E7) is expressed from human 293 cells (HEK293). It contains AA His 19 - Ser 174 (Accession # Q9NZC2-1 ).
    Predicted N-terminus: His 19
  • Molecular Characterization
    TREM2 Structure

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™)

    The protein has a calculated MW of 21.0 kDa. The protein migrates as 29-40 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
TREM2 SDS-PAGE

Biotinylated Human TREM2, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).

  • Background
    This gene encodes a membrane protein that forms a receptor signaling complex with the TYRO protein tyrosine kinase binding protein. The encoded protein functions in immune response and may be involved in chronic inflammation by triggering the production of constitutive inflammatory cytokines. Defects in this gene are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2012]
