Fig. 7From: Bioscreening and expression of a camel anti-CTGF VHH nanobody and its renaturation by a novel dialysis–dilution methodThe secondary structure of the nanobody by circular dichroism. The protein sample dissolved in 2 M urea did not show any 2-D structures. The protein samples after renaturation by dialysis–dilution or normal dilution method showed similar 2-D structures were 7 % alpha-helix and 45 % beta-sheetBack to article page
