緩沖液：

Lyophilized from a 0.2 μm sterile 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°C/-80°C. 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°C for up to one week.

靶點詳情

功能：

CD2 interacts with lymphocyte function-associated antigen CD58 (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is implicated in the triggering of T-cells, the cytoplasmic domain is implicated in the signaling function.
基因功能參考文獻：
1. A new prognostic model for HR-/HER2+ breast cancer based on the expression of MMP11 and CD2 was developed and the distant metastasis-free survival for patients in the high-risk group according to our model was significantly lower than that for those in the low-risk group. PMID: 28409241
2. These results reveal an unexpected redundancy in the human NK cell response to human cytomegalovirus and suggest that CD2 provides "signal 2" in antibody-driven adaptive NK cell responses. PMID: 27117418
3. Establish CD2 as a new susceptibility factor for systemic sclerosis in a European Caucasian population. PMID: 27385538
4. the fundamental mechanism of glycosylation of human CD2 is to promote CD2-CD58 binding by conformational adjustment of CD2 PMID: 25984915
5. CD58/CD2 is the primary costimulatory pathway in human CD28-CD8+ T cells. PMID: 26041540
6. Both the mRNA expression levels and protein expression levels of HSP27 were increased in astrocytes from POAG patients compared with those from normal control, suggesting that mutation in CD2 might pose a risk for POAG in Chinese population. PMID: 24597656
7. Although sMCs displayed immunoreactivity for one of the neoplastic antigens in the majority of SM patients, the aberrant CD2 and/or CD25 expression on sMCs is not as indicative of SM as the BMMC immunophenotype. PMID: 25402852
8. ERGdel may be a pure surrogate of CD2-positivity--which has been suggested to be a good prognositc marker in childhood ALL PMID: 24072102
9. Altogether, these results show that a high CD2 expression level is a hallmark of latently infected resting memory CD4(+) T cells in vivo. PMID: 23760244
10. Aberrant CD2 expression appears to further determine a shorter progression free survival PMID: 22634534

13. CD2-mediated priming of resting natural killer (NK) cells is unaffected by their degree of functional maturation. PMID: 22084431
14. CD2 signals more strongly to S6-ribosomal protein, whereas CD28 costimulation specifically induces signaling necessary for proper NF-kappaB activation. PMID: 22013130
15. When isolated from multiple sclerosis patients, both nonmature and effector subsets of memory CD127(low) regulatory T cells exhibit kinetically distinct defects in suppression that are evident with CD2 pathway costimulation. PMID: 21300823

20. CD2BP2 is the ligand of the membrane-proximal proline-rich tandem repeat of CD2 in detergent-soluble membrane compartments, but is replaced by Fyn SH3 after CD2 is translocated into lipid rafts upon CD2 ectodomain clustering. PMID: 12426371
