Convenient and Efficient Approach to the Permanent or Reversible Conjugation of RNA and DNA Sequences with Functional Groups

for 6 hr at 55°C. (C ) Chromatogram of a commercial sample of uridine. Conditions: RP‐HPLC analysis is performed using UV detection (254 nm) and a 5 µm Supelcosil LC‐18S column (25 cm × 4.6 mm) according to the following method: starting from 0.1 M

Conjugation of 5′‐Functionalized Oligodeoxyribonucleotides with Properly Functionalized Ligands

 Reversed‐phase column: 125‐mm × 4‐mm, 5‐µm Lichrospher 100 RP18 (Merck), CC Nucleosil 100‐5 C18 (125/4; Macherey‐Nagel), or polystyrene  reversed‐phase (PRP‐1; Hamilton)

Measurement of Arginine Metabolites: Regulators of Nitric Oxide Metabolism

including atherosclerosis, renal failure, pulmonary hypertension, and preeclampsia. Previous HPLC methods to measure these molecules rely on derivatization with ortho?phthalaldehyde, which is unstable and requires immediate pre? or post?column reactions
