WebNov 7, 2024 · The contents of sugars such as sucrose, fructose, and glucose were determined by the use of a high-performance liquid chromatograph. Here, 0.5 g of pulp was weighed, and 5 mL of 90% ethanol was added to fully grind the sample. Then, the sample was centrifuged, the supernatant collected, and ethanol used for secondary extraction. WebAlternatively, 1. Combine 95 ml of 100% ethanol with 4 ml of 3 M NaOAc (pH 4.8) and 1ml of sterile water. Mix by inversion and store at -20°C. 2. Add 2.5 volumes of cold ethanol/acetate solution to the nucleic acid solution to be precipitated. 3. Place at at -70°C for at least 30 minutes or -20°C for two hours to overnight.

WebLocked nucleic acids are modified RNA monomers. The “locked” part of their name comes from a methylene bridge bond linking the 2′ oxygen to the 4′ carbon of the RNA pentose ring (Figure 1). The bridge bond fixes the pentose ring in the 3′-endo conformation. Figure 1. A locked nucleic acid monomer. WebCommon issues in PCR are mainly associated with reaction conditions, sequence accuracy, and amplification yield and specificity.
