Form
Lyophilized powder
Buffer
Lyophilized from a 0.2 µm filtered PBS, pH 7.4
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.
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
5-10 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Chemotactic for resting CD4, CD8 T-cells and eosinophils. Binds to CCR10 and induces calcium mobilization in a dose-dependent manner.
Gene References into Functions
  1. Blockade of CCL28 or CCR10 during an acute severe respiratory paramyxoviral infection is sufficient to prevent the development of post-viral airway disease. However, the mechanism of action is unclear and requires further exploration. PMID: 28474501
  2. These data suggest that CCL28 could be useful in enhancing the IgA immune response that will likely play a pivotal role in prophylactic HIV vaccines. PMID: 22066023
  3. tumour hypoxia promotes the recruitment of regulatory T (T(reg)) cells through induction of expression of the chemokine CC-chemokine ligand 28 (CCL28), which, in turn, promotes tumour tolerance and angiogenesis PMID: 21753853
  4. demonstrate that interactions between the antimicrobial C-terminus of CCL28 with an appropriate CC chemokine N-terminal domain is important for the full antimicrobial activity of CCL28. PMID: 19830739
  5. CCL28 has dual functions in mucosal immunity as a chemokine attracting cells expressing CCR10 and/or CCR3 and also as an apically secreted molecule with a potent antimicrobial activity against a broad spectrum of microbes. PMID: 12538707
  6. MEC attracts IgA- but not IgG- or IgM-producing plasmablasts from both intestinal and nonintestinal lymphoid and effector tissues, including the intestines, lungs, and lymph nodes draining the bronchopulmonary tree and oral cavity. PMID: 12646646
  7. Epithelial cells and venular endothelium of both small intestine and colon are positive for CCL28; CCL28 plays a direct role in intestinal homing of IgA antibody-secreting cells by mediating their extravasation into intestinal lamina propria. PMID: 15356112
  8. CCL28 is a key regulator of IgA ASC accumulation in the mammary gland and thus controls the passive transfer of IgA antibodies from mother to infant. PMID: 15381732
  9. CCL28 appears to play a role in regulating eosinophil recruitment to peribronchial regions of the lung possibly by coordinated temporal production with eotaxin PMID: 15681819
  10. CCL28 mediates mucosal immunity in HIV exposure and infection PMID: 17912348
