Descripción general

Retention Mechanism: Reversed-phase
Sample Matrix Compatibility: Aqueous or methanolic solutions

  • Polyamide Resin: Particle Size: 50-160 μm, Surf pH: 4.5-7.5, Density: 0.2-0.3 cm3/g, Water Content: < 5 %
  • Useful for extracting gylcans from aqueous solutions.
  • Used to adsorb polar compounds (-OH groups, esp. phenolic compounds) from aqueous or methanolic solutions under the reversed-phase mechanism through strong hydrogen bonding between compound hydroxyl groups and amide groups of the resin
  • Also may be used for the extraction of tannins, chlorophyll, humic acid, pharmacologically active terpenoids, flavanoids, gallic acid, catechol A, protocatechuic acid, phloroglucinol, aromatic carboxylic acids, and nitroaromatic compounds
  • Irreversibly retains quinones.

Nepafenac is a nonsteroidal anti-inflammatory drug (NSAID), currently only available as 0.1% ophthalmic suspension (Nevanac®). This study utilized hydroxypropyl-β-cyclodextrin (HPBCD) to increase the water solubility and trans-corneal permeation of nepafenac. The nepafenac-HPBCD complexation in the liquid and solid states were

The endogenous metabolite itaconate has recently emerged as a regulator of macrophage function, but its precise mechanism of action remains poorly understood. Here we show that itaconate is required for the activation of the anti-inflammatory transcription factor Nrf2 (also known

Uterine leiomyomas (ULs) are benign uterine tumors, and the most notable pathophysiologic feature of ULs is excessive accumulation of extracellular matrix (ECM). Fucoidan is a polysaccharide extracted from brown seaweeds that has a wide range of pharmacological properties, including anti-fibrotic

Many broadly neutralizing antibodies (bnAbs) against HIV-1 recognize and/or penetrate the glycan shield on native, virion-associated envelope glycoprotein (Env) spikes. The same bnAbs also bind to recombinant, soluble trimeric immunogens based on the SOSIP design. While SOSIP trimers are close

Virtually the entire surface of the HIV-1-envelope trimer is recognized by neutralizing antibodies, except for a highly glycosylated region at the center of the "silent face" on the gp120 subunit. From an HIV-1-infected donor, #74, we identified antibody VRC-PG05, which


Solid Phase Extraction: Reversed-Phase Methodology

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
