產品提供形式：

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.
緩沖液：

Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
復溶：

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.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

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.
貨期：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點詳情

功能：

Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- or alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.
基因功能參考文獻：
1. The SIGLEC9 rs2075803 G/rs2258983 A haplotype, which corresponds to a Siglec-9 variant that is less effective at suppressing inflammatory response, may be a risk factor for the development of emphysema. PMID: 27878892
2. Glycophorin A, the most abundant sialoglycoprotein on erythrocytes, engaged neutrophil Siglec-9, a sialic acid-recognizing receptor known to dampen innate immune cell activation. These studies demonstrate a previously unsuspected role for erythrocytes in suppressing neutrophils ex vivo and in vitro and help explain why neutrophils become easily activated after separation from whole blood. PMID: 28416510
3. Data suggest that sialic acid-binding Ig-like lectin-9 (Siglec-9)may serve as a potential diagnostic and therapeutic target for rheumatoid arthritis (RA). PMID: 28273363
4. The mechanism of the Siglec-9 and AOC3 interaction is mediated both by protein-sugar interactions via the V domain and by the protein-protein interactions via the C22 Siglec9 domain. PMID: 27893774
5. This work defines a critical role for aberrantly glycosylated MUC1 and identifies an activating pathway that follows engagement of Siglec-9. PMID: 27595232
6. Constitutively expressed Siglec-9 inhibits LPS-induced CCR7, but enhances IL-4-induced CD200R expression in human macrophages. PMID: 26923638
7. Ligands for Siglec-8 and Siglec-9 may regulate the function of eosinophils, mast cells, neutrophils, and other cells in sinus mucosa. PMID: 26694037
8. Inflammation results in up-regulation of immuneinhibitory Siglec-8 and Siglec-9 sialoglycan ligands on human airways. PMID: 25747723
9. a polymorphism that reduced Siglec-9 binding to carcinomas was associated with improved early survival in non-small-cell lung cancer patients PMID: 25225409
10. Dasatinib enhances migration of monocyte-derived dendritic cells by reducing phosphorylation of inhibitory immune receptors Siglec-9 and Siglec-3. PMID: 24882272
11. Protein degradation of focal adhesion kinase and related molecules was induced by Siglec-9 binding to its counterreceptors via sialylglycoconjugates, leading to the modulation of adhesion kinetics of cancer cells. PMID: 24145038
12. Siglec-9 expressed on immune cells may play a role as a potential counterreceptor for MUC1 and that this signaling may be another MUC1-mediated pathway and function in parallel with a growth factor-dependent pathway. PMID: 24045940
13. The Siglec-9 peptide binding to the enzymatic groove of VAP-1 can be used for imaging conditions, such as inflammation and cancer. PMID: 21821708
14. Siglec-9 A391C was the only polymorphism related to TCR-mediated signaling in human Siglec-9, resulting in less inhibition compared to the wild type. PMID: 20733319
15. These results suggest that Siglec-9 expressed on DCs is involved in immunoregulation through ligation with mucins in an epithelial cancer patient. PMID: 20971061
16. MUC16-Siglec-9 binding likely mediates inhibition of anti-tumor immune responses. PMID: 20497550
17. Septic shock patients exhibit different ex vivo death responses of blood neutrophils after Siglec-9 ligation early in shock. PMID: 19295491
18. Binding studies on recombinant human Siglec-9 show recognition of both Neu5Ac and Neu5Gc; in striking contrast, chimpanzee and gorilla Siglec-9 strongly prefer binding Neu5Gc. PMID: 14693915
19. Siglec-9 can inhibit Fc epsilon receptor I-mediated serotonin release from rat basophilic leukemia cells and recruit the tyrosine phosphatases SHP-1 and SHP-2. PMID: 15557178
20. data suggest that apoptotic (ROS- and caspase-dependent) and nonapoptotic (ROS-dependent) death pathways are initiated in neutrophils via Siglec-9 PMID: 15827126

22. The Siglec-9 provides not only a useful marker for certain subsets of AML, but also a potential therapeutic target. PMID: 16828866
23. These results demonstrate that Siglec-9 enhances the production of the anti-inflammatory cytokine IL-10 in macrophages. PMID: 18325328
24. A review of the cytotoxic effects of natural anti-Siglec9 autoantibodies on both neutrophils and eosinophils. PMID: 18558361
