Comparison of yield, structure and chaperone activity of purified rCLU.

CLU type	Total no. of amino acid residues	No. of residues in tag	Tag as % of native CLU sequence	Yield (mg/L)	SDS-PAGE analysis, chaperone activity, Far-UV CD, FT-IR, bisANS, mass photometry
rCLU-αC-ST	465	38	~ 8	~ 20–30	Similar to pCLU
rCLU-CT	431	4	~ 0.9	~ 30–50	Similar to pCLU
