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.

Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

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.
Gene References into Functions
  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
  11. CD2-CD58/48 receptor-ligand interaction promotes and is required for nanotube formation in human natural killer cells. PMID: 23112830
  12. CD2 expression does not contribute to improve the diagnosis of systemic mastocytosis when compared with aberrant CD25 expression alone. PMID: 22222639
  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
  16. analysis of the importance of homotypic NK-to-NK cell cross-talk through 2B4/CD48 and CD2/CD58 pairs and further present their differential and overlapping roles in human NK cells PMID: 20813844
  17. PTEN expression was up-regulated on RNA and protein level in freshly isolated human CD4(+) T cells following stimulation with CD28 or CD2. PMID: 11932928

  19. Structural and functional studies of the extracellular domains of CD2 and CD58 and their complex. Review. PMID: 12369898
  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
  21. PSTPIP1 acts downstream of CD2/CD2AP to link CD2 engagement to the WASp-evoked actin polymerization required for synapse formation and T cell activation. PMID: 12530983

  28. T cell activation causes the CD58-bound CD2 to be recognized and immobilized at sites of cell-cell contact, thereby strengthening T cell-APC adhesion PMID: 17168569

  31. the synergistic synthesis of IL-8 occurs when lymphocytes are stimulated through the CD2 pathway by CD58 on HT-29 cells, resulting in TNF-alpha release that, in turn, augments IL-8 synthesis and CD58 expression by the HT-29 cells PMID: 19109405
  32. during clinical remission, increases in CD58 expression, mediated by the protective allele, up-regulate the expression of FoxP3 through engagement of the CD58 receptor, CD2, leading to the enhanced function of TREG cells that are defective in MS PMID: 19237575
