| Description: | The Gal-3 assays were performed in 384 white Opti plates in three replicates at room temperature with gentle shaking at 250-300 rpmFrom the original stocks, 2.525× working stock concentrations of His-tagged recombinant human Gal-3 (hGal-3) and that of B-ASF were prepared. From the working stock, 20 μl of hGal-3 (15 nM) and 20 μl B-ASF (15 nM) were added to the plates. In Negative Control, only hGal-3 was added. A concentration range of 50× working stocks were prepared for the compounds in 100% DMSO. Aliquots of 1 uL of the compounds were added to the wells and pre-incubated with 20 μl hGal-3 per well for 30 minutes Then 20 μl B-ASF wereadded and incubated for another 1 hour. To detect the signal, 5 μL (final conc. of 1.0 nM) terbium labelled Anti-His antibody was added and incubated for 30 min followed by adding 5 μL (final conc. of 20 nM) Streptavidin d2 and incubation for another 1 hour. The assay signal was detected using HTRF screen protocol (Excitation wavelength=340 nm, emission wavelength=615 nm/665 nm) on Envision 2104 Multilabel Reader. Data analysed using Toolset and Curve Master. Results are reported in the experimental section (IC50 in μM). |
