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.
and FAQs
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 Basically, we can dispatch the products out in 3-7 working days after receiving your orders. 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 Binds to the Fc region of immunoglobulins epsilon. High affinity receptor. Responsible for initiating the allergic response. Binding of allergen to receptor-bound IgE leads to cell activation and the release of mediators (such as histamine) responsible for the manifestations of allergy. The same receptor also induces the secretion of important lymphokines.

  1. House Dust Mite-Induced Allergic Airway Disease Is Independent of IgE and FcepsilonRIalpha. PMID: 28700253
  2. this study shows that mast cells co-cultured with macrophages alter protein expression of both cell types, and that mast cells transfer FceRI-encompassed cellular regions directly to macrophages during Francisella tularensis PMID: 27554051
  3. Tim-3 acts at a receptor-proximal point to enhance Lyn kinase-dependent signaling pathways that modulate both immediate-phase degranulation and late-phase cytokine production downstream of FcepsilonRI ligation. PMID: 26598760
  4. Conferring expression of FcepsilonRI to dendritic cells decreases the severity of food allergy and asthma in disease-relevant models suggesting anti-inflammatory IgE/FcepsilonRI signals. PMID: 25227985
  5. IgE-mediated activation of dendritic cells via IgE receptors binding in allergic Th2-type inflammation appears to be immune regulatory rather than pro-inflammatory. (Review) PMID: 26052071
  6. Specific cross-linking of the high affinity immunoglobulin epsilon receptor on the surface of bone marrow-derived mast cells and heart mast cells elicits the release of enzymatically active renin protein. PMID: 24262755
  7. Zinc-binding MT1 and MT2 are key modulators of Fc epsilonRI-induced basophil production of IL-4. PMID: 25801306
  8. Loss of Tespa1 in mouse mast cells led to hyper-responsiveness to stimulation via FcepsilonRI. PMID: 25422497
  9. IgE-mediated allergic hypersensitivity provokes release of renin from both cultured and resident cardiac mast cells. PMID: 24262755

  11. OX40L engagement impairs FcepsilonRI activation and Gab2/PI3K/Akt, but not Syk/LAT, phosphorylation PMID: 22564682
  12. FcepsilonRI, but not FcgammaR, signals induce prostaglandin D2 and E2 production from basophils PMID: 21712025
  13. data implicate Fyn as the major positive mediator of STAT5 after FcepsilonRI engagement and demonstrate importantly distinct roles for STAT5A and STAT5B in mast cell function. PMID: 22130676
  14. Reduced IgE/antigen-mediated passive cutaneous anaphylaxis is detected in mice with Piga-deficient mast cells. PMID: 21865342
  15. The PI3K binding site is involved in FcepsilonRI-dependent ARF1 activation and granule translocation to the plasma membrane in the degranulation process, further dissecting the signals required for degranulation. PMID: 21653832
  16. Whereas FcepsilonRI required Lyn and Syk for NTAL phosphorylation, Kit appeared to directly phosphorylate NTAL. PMID: 17993265
  17. This is the first observation to attribute a spatiotemporally restricted antigen-presenting function to a subset of three-week old pure BMMC expressing both high levels of surface FcepsilonRI and surface major histocompatibility complex II. PMID: 20591187
  18. Peripheral blood basophils express approximately 50% of the Fc epsilon RI density of bone marrow (BM) basophils. A 3-fold greater synthetic rate of Fc epsilon RI on BM basophils readily explains the difference. PMID: 20042574
  19. Fc epsilon RI-mediated calcium flux (dependent on PLC gamma 1) leads to degranulation of mast cells independent of PI 3-kinase PMID: 13129935
  20. FcepsilonRI stimulation triggers the formation of microtubules in a manner independent of calcium. Drugs affecting microtubule dynamics effectively suppressed the FcepsilonRI-mediated translocation of granules to the plasma membrane and degranulation. PMID: 15998803
  21. SHIP and Src homology 2 domain-containing protein tyrosine phosphatase-1 interacted with FcepsilonRI beta, and their phosphorylation was controlled by Lyn. PMID: 16272347
