Sample GSM4469947 Query DataSets for GSM4469947
Status Public on Jul 28, 2020
Title G4_d4_Cy5-PDS_1uM_plus_10uM_BMVC_comp_rep1
Sample type RNA
Source name 1uM Cy5-PDS + 10uM BMVC, G4 design 4
Organism synthetic construct
Characteristics molecule name: 1uM Cy5-PDS + 10uM BMVC
dna type: ssDNA
array treatment: 100mM KCl
Treatment protocol Microarrays were preincubated with a 100mM potassium chloride solution for 1 hour at room temperature to induce G4 formation. Binding experiments were then performed as previously described in Ray et al. ACS Chem Bio 2020.
Extracted molecule other
Extraction protocol N/A
Label Cy5
Label protocol Synthesis of Cy5-labeled pyridostatin (Cy5-PDS) is described in (Ray et al., 2020).
Hybridization protocol Microarrays were blocked with 4% non-fat dry-milk in a potassium phosphate buffer before incubation with small molecules. The binding reactions (Cy5-PDS, Cy5-PDS+BMVC, or Cy5-PDS+PDS) were carried out in a hydration chamber for 1 hour followed by one wash with 0.5% Tween-20 in 1xPBS. Finally array slides were washed and dried in 1x PBS and scanned using an Agilent Sure Scan II scanner.
Scan protocol Molecule-bound microarrays were scanned with the G5761A SureScan Dx Microarray Scanner System (Agilent) to detect Cy5 signal at two laser settings (30 and 100PMT) to ensure signal intensities were below saturation. Spot intensities from microarray images were extracted using the Agilent Feature Extraction Software and are reported as raw fluorescence units. Microarrays with the fewest number of saturated spots were used for further analysis.
Description 1uM Cy5-PDS + 10uM BMVC G4 array experiment, ssDNA + 100mM KCl
Data processing An intensity value was calculated for each target sequence by computing the median signal intensity across probes containing an identical probe identifier (ProbeID)
