Standard IHC protocol was followed to stain the tumor tissue samples using the mouse monoclonal antibody against hNIS (human Sodium Iodide Symporter) (Abcam, ab17795), ER (Estrogen Receptor) (Abcam, ab16660, ab288). Briefly, 5 µm sized paraffin embedded tissue sections were de-paraffinized with xylene and endogenous peroxidase activity was quenched with 3% H2O2 in methanol for 30 minutes in the dark. Tissue sections were dehydrated through graded alcohols and subjected to antigen retrieval using 10mM sodium citrate. Sections were washed with TBST (Tris Borate Saline Tween-20) and then blocked with 5% BSA (Bovine Serum Albumin) for one hour. Slides were incubated with the respective mouse monoclonal primary antibody diluted with TBS. Slides were then washed for 5 minutes in TBST and incubated for 1 hour with the respective HRP (Horse Raddish Peroxidase) conjugated anti-mouse secondary antibody diluted with TBS in a ratio of 1∶200. After washing, slides were incubated with DAB (3,3′-diaminobenzidine tetrahydrochloride) (Sigma) and immediately washed under tap water after color development. Slides were then counter stained with hematoxylin. Slides were mounted with DPX (dibutyl phthalate xylene) and were then observed under a light microscope (Carl Zeiss).

The 4046 tumors assembled into tissue microarrays, in BCCA series, were examined with immunohistochemistry and fluorescent in situ hybridization. Immunohistochemistry for ER, PR, HER2, and Ki67 was performed concurrently on serial sections with the standard streptavidin–biotin complex method with 3,3′-diaminobenzidine as the chromogen. Staining for ER, PR, and HER2 interpretation was as described previously (20 (link)). Briefly, the Ki67 antibody (clone SP6; ThermoScientific, Fremont, CA) was applied at a 1:200 dilution for 32 minutes, by following the Ventana Benchmark automated immunostainer (Ventana, Tucson AZ) standard Cell Conditioner 1 (CC1, a proprietary buffer) protocol at 98°C for 30 minutes. ER antibody (clone SP1; ThermoFisher Scientific, Fremont CA) was used at 1:250 dilution with 10-minute incubation, after an 8-minute microwave antigen retrieval in 10 mM sodium citrate (pH 6.0). Ready-to-use PR antibody (clone 1E2; Ventana) was used by following the CC1 protocol as above. HER2 staining was done with the SP3 antibody (ThermoFisher Scientific) at a 1:100 dilution after antigen retrieval in 0.05 M Tris buffer (pH 10.0) with heating to 95°C in a steamer for 30 minutes. For HER2 fluorescent in situ hybridization assay, slides were hybridized with probes to LSI (locus-specific identifier) HER2/neu and to centromere 17 by use of the PathVysion HER-2 DNA Probe kit (Abbott Molecular, Abbott Park, IL) according to manufacturer's instructions, with modifications to pretreatment and hybridization as previously described (29 (link)). Slides were counterstained with 4′,6-diamidino-2-phenylindole, stained material was visualized on a Zeiss Axioplan epifluorescent microscope, and signals were analyzed with a Metafer image acquisition system (Metasystems, Altlussheim, Germany). Biomarker expression from immunohistochemistry assays was scored by two surgical pathologists (T. O. Nielsen and D. Gao), who were blinded to the clinicopathological characteristics and outcome and who used previously established and published criteria for biomarker expression levels that had been developed on other breast cancer cohorts (12 (link),30 (link)). Tumors were considered positive for ER (27 (link)) or PR (31 ) if immunostaining was observed in more than 1% of tumor nuclei, as described previously. Tumors were considered positive for HER2 if immunostaining was scored as 3+ according to HercepTest criteria, with an amplification ratio for fluorescent in situ hybridization of 2.0 or more being the cut point that was used to segregate immunohistochemistry equivocal tumors (scored as 2+) (32 (link)). Ki67 was visually scored for percentage of tumor cell nuclei with positive immunostaining above the background level by two pathologists (T. O. Nielsen and D. Gao). Tissue microarray core samples with fewer than 50 tumor cells were considered uninterpretable (27 (link),28 (link)). All the stained tissue microarrays were digitally scanned, and primary image data are available for public access (http://www.gpecimage.ubc.ca; username, luminalB; password, luminalb).

GluClcryst was expressed from baculovirus-infected Sf9 cells and purified by metal ion affinity chromatography. The Fab complex was isolated by size-exclusion chromatography. The GluClcryst-Fab complex was concentrated to 1-2 mg/mL and supplemented with synthetic lipids and ivermectin. Crystallization was performed by hanging drop vapor diffusion at 4°C with a precipitating solution containing 21-23% PEG 400, 50 mM sodium citrate pH 4.5 and 70 mM sodium chloride. Cryoprotection was achieved by soaking crystals in precipitant solution supplemented with 30% PEG 400. Additional complexes were obtained by soaking crystals in cryoprotectant containing L-glutamate, picrotoxin or sodium iodide. Diffraction data were indexed, integrated and scaled and the structure solved by molecular replacement using a GLIC-derived homology model of GluClcryst and a Fab homology model as search probes. The molecular replacement phases were used to initiate autobuilding and the resulting model was iteratively improved by cycles of manual adjustment and crystallographic refinement. Function of GluCl was examined by two-electrode voltage clamp experiments and by [3H]-L-glutamate saturation and competition binding assays.

The extractions using the "BPC" method were performed as previously described [24 (link)], except that no 0.1 mm beads were used and the bead beating settings were not the same. All procedures were carried out at room temperature and centrifugations at 10000 g. The concentrated cell samples were centrifuged for 3 minutes and resuspended in 800 μl of water and 600 μl of buffer saturated phenol (pH 4.3). Addition of 0.5 g of 0.5 mm glass beads was followed by homogenization using a Bertin Precellys 24 (maximum speed, 20 seconds, twice). The sample tubes were then centrifuged for 10 minutes after which 750 μl of aqueous layer was transferred to a fresh tube, mixed with same volume of buffer saturated phenol (pH 4.3) and vortexed for 30 seconds. This was followed by centrifugation for 5 minutes and removal of 700 μl of aqueous supernatant that was then mixed with same volume of chloroform, in fresh tubes. After vortexing for 30 seconds, the samples were centrifuged for 5 minutes. At this point, 650 μl of aqueous layer were transferred to a fresh tube to which 65 μl of 3 M sodium acetate and 650 μl of isopropanol were added. The tubes were vortexed for 30 seconds and stored at -20°C for 10 minutes. After centrifugation for 5 minutes, the supernatant was removed and the pellet washed with 1 mL of 70% ethanol. One other centrifugation followed (5 minutes) and after removing the supernatant and air drying the RNA 50 μl of RNA storage solution (1 mM sodium citrate, pH 6.4, Ambion, Austin, USA) was added. The samples were stored at -80°C until analyzed.

Example 3

Multiple enzyme compositions comprising a cellulase were evaluated to determine sugar snake degradation performance as a baseline without potential surfactant synergy to assess the role of the enzyme composition versus improvement based on surfactant synergy. Compositions were prepared with 0.5 wt. % enzyme composition, 1.7 wt. % sodium citrate buffer, and water at a pH of 4.25. The four enzyme compositions tested were obtained from Novozymes and included: DRAIN EASE FLOW™, CELLUCLEAN CLASSIC 700T®, CELLUCLAST CONCENTRATED BG®, and Cellulase C. A sugar snake of equal mass was measured and the cleaning compositions were applied to it. The percent degradation of the sugar snake (based on mass) was evaluated after 2 hours of contact and after 24 hours of contact. The percent degradation is shown in FIG. 2 where 100 indicates 100% degradation. As can be seen in FIG. 2, CELLUCLAST CONCENTRATED BG® provided the best sugar snake degradation at both the 2-hour time and 24-hour time. DRAIN EASE FLOW™ and Cellulase C performed substantially similar and CELLUCLEAN CLASSIC 700T® did not appear to degrade the sugar snake at all.
