Figure 11From: Biochemical characterization of trans-sialidase TS1 variants from Trypanosoma congolenseBinding of Siglec-4 to resialylated fetuin. Vibrio cholera sialidase-treated fetuin (ASF) was treated with TS1 e-1 and 3'-SL for the times indicated as described under Material and Methods. Siglec-4 binding relative to untreated fetuin is shown. Data points are means ± standard deviations of three independent determinations.Back to article page
