Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Functions as an activating and costimulatory receptor involved in immunosurveillance upon binding to various cellular stress-inducible ligands displayed at the surface of autologous tumor cells and virus-infected cells. Provides both stimulatory and costimulatory innate immune responses on activated killer (NK) cells, leading to cytotoxic activity. Acts as a costimulatory receptor for T-cell receptor (TCR) in CD8(+) T-cell-mediated adaptive immune responses by amplifying T-cell activation. Stimulates perforin-mediated elimination of ligand-expressing tumor cells. Signaling involves calcium influx, culminating in the expression of TNF-alpha. Participates in NK cell-mediated bone marrow graft rejection. May play a regulatory role in differentiation and survival of NK cells. Binds to ligands belonging to various subfamilies of MHC class I-related glycoproteins.
Gene References into Functions
  1. Blockade of NKG2D significantly attenuated ischemia-reperfusion injury in a cardiac transplantation model. PMID: 23953572
  2. Natural killer (NK) cell-activating receptor NKG2D is important for NK-mediated killing of hepatoma McA tumor cells; NK cell cytotoxicity against McA-RH7777 is mediated by both NKp30 and NKG2D. PMID: 21106845
  3. NKG2D acts as a natural cytotoxicity receptor to stimulate perforin-mediated elimination of ligand-expressing tumor cells. PMID: 12421908
  4. NKG2D is required for cytolysis of tumor cells, including autologous tumor cells from patients with ovarian cancer, and in vivo antitumor activity PMID: 16339517
  5. We have reported the involvement of NKR-P2 in rat dendritic cell (DC) activation. We demonstrate the potential of agonistic anti-NKR-P2 mAb (1A6), which mimics the NKR-P2 ligand and induces activation and maturation of DCs. PMID: 17369187
  6. A novel role of Irp94 as a ligand for NKR-P2 on DCs, which in turn executes both innate and adaptive immunity, was demonstrated. PMID: 18178852
  7. In vitro cytotoxic assays reveal that a subset of rat monocytes/macrophages expressing both CD4 and CD8 antigens can kill certain tumor cells in a cell-cell contact-dependent manner through recognition of NKG2D ligands. PMID: 18292522
  8. the splice forms of NKG2D arise from alternative promoters and that the NKG2D-L promoter is derived from a B1 retrotransposon. PMID: 19304755
