Kinetic analysis of SDF-1α cleavage by human serum. Recombinant SDF-1α (1-68) was incubated at room temperature for the indicated times (0 to 20 hours) with 10% human serum and analyzed by mass spectrometry. The average molecular mass after deconvolution of the indicated ion peaks (left) is shown on the right. Representative experiment is shown.
