Affinity capture and exclusion of albumin. SDS PAGE analysis of particles incubated with the following chemokines, mucosae-associated epithelial chemokine (MEC/CCL28), stromal cell-derived factor-1 beta, (SDF-1β/CXCL12b), and eotaxin-2 (CCL24), in the presence of bovine serum albumin (BSA) to which the chemokines asssociate. Solutions of the chemokines and BSA are shown in lanes 1, 4, and 7. After incubation with the particles, no chemokine was left in the supernatant (S, lane 2, 5, and 8) and all the chemokine solution phase molecules were captured by the particles (P, lanes 3, 6, and 9), while albumin was totally excluded by particles.
