Figure 1From: Evaluation and comparison of the potential of two ferritins as anti-tick vaccines against Haemaphysalis longicornisPurification of recombinant HlFERs (rHlFERs). His-tagged rHlFERs (rHlFER1 and rHlFER2) were expressed in E. coli and then purified through Ni-affinity chromatography and dialysis against PBS.
