Recombinant Human C-C motif chemokine 23 protein (CCL23) (Active)

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. {ECO:0000269|PubMed:15905581}.

Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration of 10-50 ng, ml.

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.
