μL for dsDNA), cuvette-free operation, short measurement time, high accuracy and precision, and fewer solvent restrictions. ... alternative to gel-based quantification, megaprimer concentrations—now free from plasmid contaminants—may also be assessed by an ultralow volume spectrophotometer (e.g., Nanodrop—Thermo Fisher Scientific, Wilmingon, DE). For the second iteration of PCR (''EZClone Reaction''), follow the Stratagene instructions. This is best done on a nanodrop spectrophotometer (Thermo Scientific) due to the small volume.. The cDNA can then be purified using a Clean and Concentrator-5 Kit (Zymo Research) following the manufacturer's instructions except that the cDNA–HEPES buffer mix should be mixed with 1 ml of binding buffer before.
Solid-state UV lasers are available but do not have the required intensity for use as a fluorescence source.. Also from Thermo Fisher Scientific is a fluorescence version of the NanoDrop, the NanoDrop 3300 Fluorospectrometer, which uses UV, blue, and white LED excitation sources covering a range from 400 to 750 nm,. Use the Alternative Protocol described in the kit instruction manual for samples less than 250 μl from the mouse tail vein. 3. Determine RNA yields by UV absorbance using a Nanodrop. Assess RNA quality with the ThermoScientific NanoDrop1000 (Resnick et al. 2009) Blood Cell RNA 1. Isolate blood cell total RNA using. The RNA concentration was quantified spectrophotometrically using the. NanoDrop 2000 spectrophotometers (Thermo Fisher Scientific), and then reverse transcribed into cDNA using the SuperScript III. First-Strand Synthesis System (Thermo Fisher Scientific), according to the manufacturer's instructions. The cDNA was. Mouse zygotes were injected with five components for each targeting scheme: two single guide RNAs (sgRNAs) targeted to sequences flanking... Protein concentrations were determined using BCA Protein Assay Reagent (23225, Thermo Fisher Scientific) followed by measurement with NanoDrop. DNA was quantified with a Thermo Scientific NanoDrop 2000 spectrophotometer (Thermo Scientific, Waltham, Massachusetts, USA).. and adenovirus (ATCC VR-15) into pGC vectors according to manufacturer's instructions (pGC Blue Cloning & Amplification Kit, Lucigen, Middleton, Wisconsin, USA). Therefore, ppa could be a strong biotechnological candidate, comparable to GNA and PTA, for use in efforts to produce aphid-resistant plants.. using TRIzol Reagent, and RNA concentration and purity were evaluated with a NanoDrop 2000 spectrophotometer (Thermo Scientific Branch, Beijing, China).
