Description

The TREM-1 protein is a key cell surface receptor that amplifies inflammatory responses in innate and adaptive immunity. Ligands such as PGLYRP1, HMGB1 or HSP70 activate TREM-1, leading to multimerization and complex formation with TYROBP/DAP12. TREM-1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived TREM-1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of TREM-1 Protein, Mouse (HEK293, His) is 182 a.a., with molecular weight of ~38.0 kDa.

Background

TREM-1, a cell surface receptor, assumes pivotal roles in both innate and adaptive immunity by robustly amplifying inflammatory responses. Upon activation by diverse ligands such as PGLYRP1, HMGB1, or HSP70, TREM-1 undergoes multimerization and forms a complex with the transmembrane adapter TYROBP/DAP12. This initiates a SYK-mediated cascade of tyrosine phosphorylation, activating downstream mediators like BTK, MAPK1, MAPK3, or phospholipase C-gamma. Consequently, this cascade facilitates the release of pro-inflammatory cytokines and/or chemokines by neutrophils and macrophages, promoting their migration and thereby amplifying inflammatory responses triggered by bacterial and fungal infections. Beyond microbial interactions, TREM-1 also contributes to the amplification of inflammatory signals initiated by Toll-like receptor (TLR) and NOD-like receptor engagement, playing a crucial role in the pathophysiology of various acute and chronic inflammatory diseases, including septic shock and atherosclerosis. In its monomeric state, TREM-1 forms homomultimers upon activation and interacts with TYROBP/DAP12 and TLR4, further highlighting its intricate involvement in the regulation of immune responses.

Molecular Weight

Approximately 38.0 kDa

Purity

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

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US;may vary elsewhere.

Help & FAQs
  • How should lyophilized recombinant proteins be reconstituted and stored?

    1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss. 2. Taking 10 μg as an example, first add 20 μL of reconstituted solution provided by MCE and use a pipette to gently resuspend the lyophilized protein until it is fully dissolved.. (For most proteins, the reconstitution solution we provide is sterile water. If a diluent other than water is required, it will be indicated in the product's Certificate of Analysis (COA).). 3. Add an additional 80 μL of buffer/culture medium containing carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% trehalose), and then use a pipette to gently mix until uniform. The final concentration is should not be lower than 100 μg/mL. 4. Aliquot at least 20 μL per tube. 5. After aliquoting, store it frozen at a temperature ranging from -20ºC to -80ºC, and it can be preserved for 3 to 6 months.

  • How should solution-form recombinant proteins be stored?

    1. The product can be stored in its original form and diluted as needed upon use. 2. Alternatively, dilute with a buffer/culture medium containing a carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), mix well by pipetting, and ensure that

  • Why is it necessary to add carrier proteins?

    Carrier proteins are commonly added to enhance the stability of recombinant proteins, preventing them from adhering to the walls of the container during freezing or thawing processes. Plastic tubes have a certain adsorptive capacity for proteins, which may lead to difficulty in separating the protein from the tube walls, resulting in a decrease in the actual concentration of the protein in the solution and thus affecting its activity. To minimize such losses, it is recommended to add a commonly used carrier protein solution prior to the long-term storage of recombinant protein products.

  • Carrier protein types and options?

    In cases where the carrier protein is not expected to influence the experimental outcomes, an appropriate carrier protein, such as 0.1% BSA (Bovine Serum Albumin), 5% HSA (Human Serum Albumin), 10% FBS (Fetal Bovine Serum), or 5% trehalose, can be incorpo
