Chemiluminescence

Chemiluminescence is a form of luminescence where light is emitted from a chemical reaction.
This process occurs when a molecule in an excited state relaxes to a lower energy state, releasing a photon.
Chemiluminescence has a wide range of applications in various fields, including analytical chemistry, biomedical research, and environmental monitoring.
It is often used as a detection method in assays and imaging techniques, providing sensitive and quantitative measurements.
Chemiluminescence can be a valuable tool for researchers, offering insight into biological processes, chemical reactions, and the presence of specific analytes.
Understanding the principles and applications of chemiluminescence is crucial for optimizing experimental workflows and obtaining reproducible, data-driven insights.

Tobacco leaves were harvested approximately 70 hours after infiltration with Agrobacterium containing the plasmid encoding the respective genes under control of the 35S promoter. Tissue was frozen in liquid nitrogen, protein was extracted as described by [30 ] and assayed as described by [18 (link),17 (link)].
Firefly Luciferase and Renillia luciferase were assayed using the dual luciferase assay reagents (Promega, Madison, USA). After inoculation and a transient incubation of 2–4 days, 2 cm leaf discs were harvested and ground in 500 μl of Passive Lysis Buffer. Five μl of a 1/100 dilution of this crude extract was assayed in 40 μl of Luciferase Assay Buffer, and the chemiluminescence measured. 40 μl of Stop and Glow™ buffer was then added and a second chemiluminescence measurement made. Absolute RLU were measured in a Turner 20/20 luminometer, with a 5 second delay and 15-second measurement. Data was collected as ratio or, for multiple data points (e.g. several leaves of different ages were infiltrated), the regression-gradient and regression-standard-error were used as a measure of relative promoter strength. Ratios are without units as both the light measurement and protein concentrations are identical. Background controls were run with only the promoter-LUC, 35S-REN reporter plasmid (no TF). In some cases, positive controls were run using a TF with known activity.

Protein samples were treated for 30 min at 50°C in a sample-treating solution containing 2% SDS and 5% β-mercaptoethanol. The samples were then loaded onto a 12% or 15% SDS-polyacrylamide gel (7.0×8.3 cm ×0.75 mm) and electrophoresed using Mini-Protean Tetra system (Bio-Rad) at 15 mA (current constant). After electrophoresis, proteins separated on the gel were transferred onto a methanol-activated PVDF membrane (Immobilon-P, pore size 0.45 µm, Millipore) or a nitrocellulose membrane (Protran BA85, pore size 0.45 µm, Whatman) for 2 h using TE22 Mighty Small Transfer system (Hoefer Scientific) at 100 V (voltage constant). The membrane was then treated with or without phosphate-buffered saline (PBS) containing 0.4% PFA for 30 min at room temperature, followed by blocking for 1 h with 5% skim milk (Carnation) in Tris-buffered saline containing 0.1% Tween-20 (TBS-T). The membrane was then incubated for 1 h with a primary antibody in TBS-T containing 1% skim milk. As primary antibody, mouse monoclonal anti-α-syn antibodies 4D6 and LB509 (Santa Cruz Biotechnology) and rabbit monoclonal anti-phospho α-syn antibody EP1536Y (Epitomics, Burlingame, CA) were used at a dilution 1∶1,000, and rabbit polyclonal anti-actin antibody (Sigma) was also used at a dilution 1∶5,000.

M-PER mammalian protein extraction reagent (Thermo Scientific, USA) was used to
lyse the human cell lines 24 hr post-transfection, zebrafish embryos at 24 hour
post-fertilization (hpf) and mouse liver 3 day post-injection (dpi). Each lysate
was separated by 12% sodium dodecyl sulfate polyacrylamide gel
electrophoresis (SDS-PAGE) and transferred to nitrocellulose membrane (Pall
Corporation; NY, USA). Subsequently, the membrane was probed with the indicated
primary antibody (anti-EGFP [1∶1000, Santa Cruz Biotechnology,
catalog # sc-9996] and anti-DsRed [1∶1000, Clontech, catalog #
632393]), washed with TBST (0.2 M Tris, 1.37 M NaCl,0.1% Tween-20,
pH7.6), probed with HRP-conjugated goat anti-mouse antibody (1∶4000, Santa
Cruz Biotechnology, catalog # sc-2005). The bound antibody was detected by
enhanced chemiluminescence (AniGen, Korea) and then exposed to X-ray film (AGFA,
Belgium).
Because anti-DsRed antibody has been successfully used to decorate mCherry
protein [12] (link),
anti-DsRed antibody was used to visualize the mCherry protein.

Genomic DNA (gDNA) was extracted from approximately 600 mg of Stevia leaves using cetyltrimethylammonium bromide (CTAB)-based extraction method [45 ]. The final gDNA pellet was washed with ice-cold 75% ethanol and dissolved in water.
PCR amplification was carried out from 100 ng of gDNA extracted from each line of transgenic Stevia to check for the presence of T-DNA using forward primers specific to the CaMV 35S promoter and reverse primers specific to the 3′-end of SrDXS1 or SrKAH (Additional file 9: Table S1).
Southern blot analysis for detection of transgene integrations and number of integration sites was performed using a DIG-labelled probe specific to the full-length nptII (Roche). The purity of the synthesized probes was checked by electrophoresis on a 1% agarose gel. gDNAs extracted from the SrDXS1-OE and SrKAH-OE lines were digested with HindIII and XbaI, respectively. After digestion, the fragments were resolved on a 0.8% agarose gel together with DIG-labelled DNA molecular weight marker II (Roche). The agarose gel was treated with 0.2 M HCl followed by denaturation solution (0.5 M NaOH, 1.5 M NaCl) and neutralization solution (1 M Tris-Cl pH 7.4, 1.5 M NaCl) and transferred to a positively charged nylon membrane (Hybond-N+, GE healthcare life sciences) in 20x SSC (3.0 M NaCl, 0.3 M sodium citrate, pH 7.0). After the transfer, UV-crosslinking was carried out using Stratalinker 2400 (Stratagene, USA). Then, DIG-based Southern blot hybridization was performed according to manufacturer’s instructions (Roche). Chemiluminescence from the membrane was acquired with the ChemiDoc Touch Imaging System (Bio-Rad, USA).
