Chemokines are members of the chemotactic cytokines family implicated in various immunoregulatory functions. The CXC-chemokine stromal cell derived factor-1 (SDF-1alpha) was purified from the culture medium of murine bone marrow stromal cell line (MS-5) by affinity and reversed-phase liquid chromatography. Yield and purity were assessed by capillary electrophoresis (CE) with reference to the human SDF-1alpha from recombinant DNA technology. CE technique was useful to evaluate the purity of human SDF-1alpha from chemical synthesis and to resolve murine and human SDF-1alpha, differing by only one amino acid. Chemotactic activity of the murine SDF-1alpha was tested on the basis of CE quantification.

Abstract
Chemokines are members of the chemotactic cytokines family implicated in various immunoregulatory functions. The CXC-chemokine stromal cell derived factor-1 (SDF-1alpha) was purified from the culture medium of murine bone marrow stromal cell line (MS-5) by affinity and reversed-phase liquid chromatography. Yield and purity were assessed by capillary electrophoresis (CE) with reference to the human SDF-1alpha from recombinant DNA technology. CE technique was useful to evaluate the purity of human SDF-1alpha from chemical synthesis and to resolve murine and human SDF-1alpha, differing by only one amino acid. Chemotactic activity of the murine SDF-1alpha was tested on the basis of CE quantification.Pubblicazioni consigliate
