  • Application Notes
    Optimal working dilution should be determined by the investigator.
    Comment

    Biological activity: Bioactivity was measured by its property to chemoattract THP-1 cells in a dose dependent manner.

    Restrictions
    For Research Use only
  • Format
    Liquid
    Reconstitution
    For maximum results, quick spin vial prior to opening. Stock solutions should be prepared at no less than 10 μg/mL in sterile buffer (PBS, HPBS, DPBS, and EBSS) containing carrier protein such as 1 % BSA or HSA. After dilution, the cytokine can be stored between 2 °C and 8 °C for one month or from -20 °C to -70 °C for up to 3 months.
    Buffer
    0.22 μm filtered protein solution is in PBS.
    Handling Advice
    Avoid repeated freeze/thaw cycles.
    Storage
    -20 °C
    Storage Comment
    Unopened vial can be stored between 2°C and 8°C for three months, at -20°C for six months, or at -70°C for one year.

    Background
    Human CCL23 was initially identified in a cDNA library derived from human endothelial cells. CCL23 has six cysteine residues and posseses a separately encoded amino-terminal domain, characteristic of similar chemokines CCL6, CCL9, and CCL15. These four chemokines are weak agonists for CCR1, nevertheless, they can be proteolytically cleaved in the amino-terminus, resulting in forms with higher chemoattractant activity. Thus, NH2-terminus truncated forms of CCL23 have been detected in synovial fluid of patients with rheumatoid arthritis (RA). In vitro studies have shown that CCL23 can be processed by MMPs at the amino and carboxyl terminus. CCL23 (26-99) is the predominant stable form after using MMP1, 2, 3, 7, 8, or 12. CCL23 (30-99) is formed by MMP14, elastase, and proteolytic activity in arthritic synovial fluid. In addition, CCL23 has been detected in serum of patients with active RA, in conjunction with CXCL13, TNFSR9, M-CSF, and TNFα. High levels in serum of these cytokines correlate with joint inflammation and have been considered as biomarkers of active RA. Also, high levels of CCL23 have been detected in plasma of atherosclerotic patients. High expression of CCL23 has been found in skin of atopic dermatitis patients, and in mucosal epithelial cells and inflammatory cells in sinonasal tissues of patients with chronic rhinosinusitis (CRS).
    Molecular Weight
    The 75 amino acid recombinant protein has a predicted molecular mass of approximately 8.5 kDa. The DTT-reduced and non-reduced protein migrate at approximately 12 and 14 kDa by SDS-PAGE respectively. The N-terminal amino acid is Arg.
