Purification of Gc proteins by vitamin D affinity column chromatography. CBB staining patterns of two independently prepared samples of Gc1F, purified with His-Trap column chromatography (A, Gc1F 1 and 2) and blotting patterns with anti-Gc antibody (B, Gc1F 1 and 2). The eluate from the His-Trap column (A, Gc1F 1) was subjected to vitamin D affinity column chromatography. Affinity-purified Gc1F was detected by CBB staining (C). Gc1S and Gc2 were similarly purified and stained with CBB (D). The CBB staining pattern of mouse GcMAF purified by a single step of vitamin D affinity column chromatography (E). Full-length gels and blots are included in a Supplementary Fig. 4.
