UCT Flagship Sorbent Clean Screen® DAU cited in Cardiac Study

August 24th, 2018

In a recent study by Guillermo Alberto Keller et al., published in Journal of Opioid Management , UCT’s Clean Screen® DAU was used to extract Propoxyphene (DPX)  and norpropoxyphene (NPX) from human plasma and analyzed by GC-MS. Plasma samples (500 µl) were treated with a strong alkali hydroxide to form NPX amide and extracted using CSDAU203. The recovery of the procedure was higher than 81%.

In a recent study authored by Ibraheem M. Attafi et al., published in the Arab Journal of Forensic Sciences & Forensic Medicine ((2018) 7(1) 922-930)), a postmortem case report aimed to identify and determine the concentration of cathine and cathinone in different body organs and green chewed plants found in the mouth of the deceased. Extraction of the khat compounds was performed using UCT’s Clean Screen® DAU in conjunction with LC-MS/MS quantitative analysis to confirm that samples were positive for cathinone and cathine.

DAU Sorbent cited in Equine Toxicology Study

July 16th, 2018

In a recent study published in Drug Testing and Analysis (DOI: 10.1002/dta.2378), authored by Heather K. Knych et al, UCT’s Clean Screen® DAU was employed to extract grapiprant following oral administration to exercised thoroughbred horses. Grapiprant is a newly approved non‐ cyclooxygenase inhibiting non‐steroidal anti‐inflammatory drug that has demonstrated efficacy and safety in other species. As long‐term use of these drugs can adversely impact the health of the horse, anti‐inflammatories with a more favorable safety profile are warranted.
