Chemokine(C-C motif) ligand 23(CCL23), also known as MIP-3 and MPIF-1, is a small cytokine belonging to the CC chemokine family. It is mapped to 17q12. CCL23 is predominantly expressed in lung and liver tissue, but is also found in placenta, bone marrow and some cell lines of myeloid origin. MPIF1 has chemotactic activity on resting T lymphocytes and monocytes, lower activity on neutrophils. It has also been attributed to an inhibitory activity on hematopoietic progenitor cells that give rise to granulocyte and monocyte lineages. Moreover, CCL23 is a ligand for the chemokine receptor CCR1.

Useful in Sandwich ELISA for Quantitative Detection of Antigen. Aliquot 0.1ml per well of the 2000pg/ml,1000pg/ml, 500pg/ml, 250pg/ml, 125pg/ml, 62.5pg/ml, 31.2pg/ml human CCL23 standard solutions into the precoated 96-well plate. Add 0.1ml of the sample diluent buffer into the control well (Zero well). Add 0.1ml of each properly diluted sample of human cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. It is recommended that each human CCL23 standard solution and each sample be measured in duplicate.
