Large quantity production with extreme convenience of human SDF-1alpha and SDF-1beta by a Sendai virus vector

FEBS Lett. 1998 Mar 20;425(1):105-11. doi: 10.1016/s0014-5793(98)00207-5.


We describe a robust expression of human stromal cell-derived factor-1alpha (SDF-1alpha) and SDF-1beta, the members of CXC-chemokine family, with a novel vector system based upon Sendai virus, a non-segmented negative strand RNA virus. Recombinant SDF-1alpha and SDF-1beta were detected as a major protein species in culture supernatants, reached as high as 10 microg/ ml. This remarkable enrichment of the products allowed us to use even the crude supernatants as the source for biological and antiviral assays without further concentration nor purification and will thus greatly facilitate to screen their genetically engineered derivatives.
