Reference and test DNA (1 μg of each) were mixed in a total of 250 μl hybridisation solution (containing 25 μl 10× Agilent blocking agent, 125 μl Agilent hybridisation buffer and water to volume), heated at 100°C for 3 min followed by 37°C for 30 min then added to a microarray slide.
For Ki67 staining, Ki67 antibody (Vector Labs) was used at 1/100 dilution, and antigen unmasking was performed in citrate buffer and water bath incubation for 50 min at 99°C.
All buffers and water were pyrogen-free.
The release of Ag+ ions from both the 1- and 3 h-cross-linked nAg-containing gelatin fiber mats – by the total immersion method in acetate buffer and distilled water (both at a skin temperature of 32 °C) – occurred rapidly during the first 60 min, and increased gradually afterwards; while that in SBF (at the physiological temperature of 37 °C) occurred more gradually over the testing period.
All solids were dissolved directly into assay buffer and briefly water bath sonicated at room temperature for 10 min.
100 ng of genomic DNA from each individual was digested in a 50 μL reaction with 100 units each of NlaIII and MluCI restriction enzymes (New England Biolabs, Beverly MA, USA), NEB Buffer 4, BSA and water for 3 hrs at 37°C, without a heat kill step.
The solubilities of these buffers in water and at several concentrations of 1,4-dioxane at 298.15 K have also been determined from the experimental results of density measurements.
Prepare hybridization buffer and incubate it at 85°C water bath for 10 min, then cool on ice.
Stock standard solutions of decitabine at concentration of 114, 228, 456 and 1140 ng/ml, were prepared individually in water solution or lysis buffer and stored at −80°C until analysis.
These measurements, carried out both in water and in buffer and at the variance of pH, temperature and time, support the excellent colloidal stability of the amino-graft PVP nanogels and their redispersability from the dry physical form.
