線性度:
To assess the linearity of the assay, samples were spiked with high concentrations of human MPIF-1/CCL23 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

標準曲線:
These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.
Shows chemotactic activity for monocytes, resting T-lymphocytes, and neutrophils, but not for activated lymphocytes. Inhibits proliferation of myeloid progenitor cells in colony formation assays. This protein can bind heparin. Binds CCR1. CCL23(19-99), CCL23(22-99), CCL23(27-99), CCL23(30-99) are more potent chemoattractants than the small-inducible cytokine A23.

CCL23 is posttranslationally modified by trypsin-like serine proteases and CCL23(47-117) might be a major active form of CCL23 in nasal polyps with chronic rhinosinusitis. PMID: 26560043
The coexistence of diabetes and oxidative stress independently affected CCL23 levels, while the presence of Cardiovascular disease and inflammation had no impact on its concentrations. PMID: 24995525
ADAMTS 8, CCL23, and TNFSF15 are implicated in anti-angiogenic activities PMID: 24384427
Data show CCL23 stimulates chemotaxis of human THP-1 monocytes and enhances release of MMP-2, and suggest it plays a role in atherogenesis. PMID: 21656154
Overproduction of CCL23 in nasal polyps might contribute to the pathogenesis of eosinophilic chronic rhinosinusitis with nasal polyps PMID: 21497884
Patients with systemic sclerosis who had elevated CCL23 levels had shorter disease duration, and a higher frequency of pulmonary arterial hypertension. Serum CCL23 level was increased in early phase of disease and could be a marker for disease activity. PMID: 20824279
Fresh eosinophils contained trace amounts of CCL23 protein. CCL23 was significantly released into the supernatant when the eosinophils were stimulated with GM-CSF or IL-5 but not with IFN-gamma or immobilized sIgA. PMID: 21646793

CKbeta8 transduces the chemotaxis signal through the G(i)/G(o) protein, phospholipase C, protein kinase C delta and NF-kappaB. PMID: 19951712
CCL23 promoted chemotactic migration and differentiation of endothelial cells, and neovascularization in the chick chorioallantoic membrane PMID: 15927850
May play a direct role in angiogenesis via upregulation of matrix metalloproteinase (MMP)-2 expression. PMID: 16378600
Collectively, these data suggest a link between the inducible phenotype of CCL23 expression in monocytes by the prototype Th2 molecule pair IL-4/STAT6 and the increased number of CCL23-expressing cells in skin of atopic dermatitis patients. PMID: 17371990
A peptide ligand termed SHAAGtide is cleaved from CCL23; is itself an attractant of monocytes and neutrophils in vitro; recruits leukocytes in vivo; is more potent than other natural agents with activity for FPRL1; receives authors' designation "CCR12." PMID: 17513790
This protein may participate in the malignant progression of certain human cancer cells that overexpress ErbB2 through the transactivation of ErbB2 tyrosine kinase. PMID: 18258606
CCL23, M-CSF, TNFRSF9, TNF-alpha, and CXCL13 are predictive of rheumatoid arthritis disease activity and may be useful in the definition of disease subphenotypes and in the measurement of response to therapy in clinical studies. PMID: 18668547
these findings suggest that CCL23 results in up-regulation of KDR/flk-1 receptor gene transcription and protein expression and that KDR/Flk-1 up-regulation induced by CCL23 may contribute to potentiation of VEGF action in angiogenesis. PMID: 19265684
