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.
Form
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
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℃/-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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Functions coreceptor to limit the innate immune responses to viral infections; signaling occurs via FCER1G. Down-regulates the production of IFNA1, IFNA2, IFNA4, IFNB1 and TNF by plasmacytoid dendritic cells that have been exposed to influenza virus or cytidine-phosphate-guanosine (CpG) dinucleotides, indicating it functions as negative regulator of TLR7 and TLR9 signaling cascades. Down-regulates interferon production in response to interaction with BST2 on HIV-1 infected cells. Activates a signaling cascade in complex with FCER1G that results in phosphorylation of Src family and Syk kinases and thereby triggers mobilization of intracellular Ca(2+). Does not interfere with the differentiation of plasmacytoid dendritic cells into antigen-presenting cells.
Gene References into Functions
  1. Crosslinked ILT7 favours the differentiation of immature plasmacytoid dendritic cells into antigen-presenting cells rather than IPC. PMID: 24586760
  2. ILT7 may exert its immunomodulatory activity only on immature circulating plasmacytoid dendritic cells (pDCs), providing a basic homeostatic mechanism rather than negative feedback control on activated pDCs. PMID: 23401591
  3. Intracellular expression of the TCL1 as well as membrane and intracellular expression of ILT7 in plasmacytoid dendritic cell leukemia (pDCL) samples and 61 non-pDC acute leukemia samples, were tested. PMID: 22674796
  4. the expression of immunoglobulin-like transcript 7, in plasmacytoid dendritic cells PMID: 12384430
  5. ILT7 protein associates with the signal adapter protein Fc epsilonRI gamma to form a receptor complex in dendritic cells. PMID: 16735691
  6. key regulator of human pDC function and interferon type I production. PMID: 18048391
  7. Data show that BST2 directly binds to purified ILT7, initiates signaling via the ILT7-FcepsilonRIgamma complex, and regulates TLR7/9 responses in plasmacytoid dendritic cells. PMID: 19564354
