  • Choline Oxidase in a standard captured ELISA using Peroxidase Conjugated Streptavidin and ABTS (2,2'-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes at room temperature. (abcam.com)
  • vivo
  • Introduction: In many human cancers, including prostate cancer, malignant transformation and disease progression are associated with changes in the choline containing phospholipids that can be visualized using magnetic resonance spectra (MRS). Using current MRI/MRS technologies, the choline resonance that can be measured in vivo appears a single peak in the proton spectral array. (aacrjournals.org)
