Study TitleLCMS analysis of amino acid levels in PDAC interstitial fluid samples upon ass1 cancer cell knock out
Study SummaryWe used CRISPR-Cas9 to knockout (KO) Ass1 in mPDAC cells. We tested if inhibiting arginine de novo synthesis would impair PDAC tumor growth. To test this, we generated orthotopic PDAC tumors with mPDAC-Ass1 KO cells and control cells where Ass1 was re-expressed (Ass1KO; mASS1).

Collection:

Collection ID:CO002623
Collection Summary:Tumors were rapidly dissected after euthanizing animals. Tumors were weighed and rinsed in blood bank saline solution (150 mM NaCl) and blotted on filter paper (VWR, Radnor, PA, 28298–020). The process of dissection and tumor preparation took < 3min. Tumors were cut in half and put onto 20µm nylon mesh filters (Spectrum Labs, Waltham, MA, 148134) on top of 50 mL conical tubes, and centrifuged for 10min. at 4°C at 400xg. IF was then collected, snap-frozen in liquid nitrogen and stored at -80°C until further analysis.
Sample Type:Interstitial Fluid
