HA chromatography of Te-PC and Te-APC.
Notes: (A) Elution process of the first HA chromatography. The sample was eluted with different PBS concentration gradients: first at 0.001M, followed by 0.005M, 0.01 M, 0.020 M, 0.05 M, and last at 0.10 M. The flow rate was 0.5 mL min−1. (B) Elution process of the second HA chromatography. The sample was eluted with different PBS concentration gradients: first at 0.005, 0.02 M; followed by 0.05 M; and last at 0.10 M. The flow rate was 0.5 mL min−1.
Abbreviations: Min, minutes; PBS, phosphate-buffered saline; HA, hydroxyapatite; Te-PC, tellurium-containing phycocyanin; Te-APC, tellurium-containing allophycocyanin.
