Form Liquid or 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 If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Protein FAQs
Storage Condition Store at -20°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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Plays a role in T-cell activation and in the adaptive immune response. Regulates the proliferation of activated T-cells. Regulates the release of cytokines and IFNG by activated T-cells. Mediates the response of T-cells toward infected and transformed cells that are characterized by high levels of phosphorylated metabolites, such as isopentenyl pyrophosphate.
Gene References into Functions
  1. Microtubule-associated protein 4 (MAP4) controls the dynein-dependent transport of BTN3A1 in response to nucleic acid stimulation, thereby identifying MAP4 as an upstream regulator of BTN3A1. Thus, the depletion of either MAP4 or BTN3A1 impairs cytosolic DNA- or RNA-mediated type I IFN responses. PMID: 27911820
  2. results show that ligand binding to BTN3A1 induces a conformational change within the intracellular domain that involves the JM region and is required for full activation. PMID: 28705810
  3. findings show that changes in the juxtamembrane domain of BTN3A1, but not its transmembrane domain, induce a markedly enhanced or reduced gammadelta T cell reactivity PMID: 28461569
  4. These findings support intracellular sensing of prenyl pyrophosphates by BTN3A1 rather than extracellular presentation. PMID: 26475929
  5. Human gamma-delta T cells are activated by cytosolic interactions of BTN3A1 with soluble phosphoantigens and the cytoskeletal adaptor periplakin. PMID: 25637025
  6. evidence that gene(s) on Chr6 in addition to BTN3A1 are mandatory for PAg-mediated activation of Vgamma9Vdelta2 T cells. PMID: 24890657
  7. Ligand binding to the BTN3A1 B30.2 domain affects residues in the juxtamembrane region, suggesting ligand-induced conformational change. PMID: 25065532
  8. These studies demonstrate that internal sensing of changes in pAg metabolite concentrations by BTN3A1 molecules is a critical step in Vgamma9Vdelta2 T cell detection of infection and tumorigenesis. PMID: 24703779
  9. BTN3A1 represents an antigen-presenting molecule required for the activation of Vgamma9Vdelta2 T cells. PMID: 23872678
  10. investigation of role of CD277 in activation/inactivation of T-lymphocytes: Data indicate that modulation of CD277 interaction (with agonists or blocking antibodies) with T-cell antigen receptor can modulate activation/inactivation of T-lymphocytes. PMID: 22767497
  11. BTN3A1 is necessary for Vgamma9Vdelta2 activation and begin to unravel the extracellular events that occur during stimulation through the Vgamma9Vdelta2 T cell receptor. PMID: 22846996
  12. CD277 triggering is not involved in CD16- or NKp46-induced NK cell activation. PMID: 21918970
  13. Results point to a role for CD277 up-regulated by microenvironmental signals in the acquisition of a regulatory phenotype by ovarian tumor-associated myeloid cells. PMID: 21113407
