Description

The PILR-β protein is a paired immune system modulator and is considered a signal-activated receptor that associates with cell surface ITAM adapters such as DAP12. It interacts with CD99 and may help natural killer cells recognize target cells and activate dendritic cells. PILR-beta Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived PILR-beta protein, expressed by HEK293 , with C-hFc labeled tag. The total length of PILR-beta Protein, Mouse (HEK293, Fc) is 165 a.a., with molecular weight of 55-60 kDa.

Background

PILR-beta Protein, a member of paired receptors integral to immune system regulation, is posited as a cellular signaling activating receptor that forms associations with ITAM-bearing adapter molecules on the cell surface. This protein is suggested to interact with DAP12 and functions as a receptor for CD99, potentially contributing to target cell recognition by natural killer cells and participating in the activation of dendritic cells. The observed interaction with CD99 and the likely association with DAP12 underscore PILR-beta's role in cellular signaling pathways, highlighting its potential impact on immune responses and cellular recognition mechanisms.

Biological Activity

Immobilized PILR-beta at 2 μg/mL (100 μL/well) can bind Biotinylated CD99. The ED50 for this effect is 2.353 µg/mL.

Molecular Weight

Approximately 50-70 kDa due to the glycosylation

Purity
  • Greater than 90% 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
