Collection:
| Collection ID: | CO003297 |
| Collection Summary: | After two weeks of treatment, retroorbital whole blood samples were collected following Isoflurane sedation. The samples were obtained using heparinized capillary tubes (Catalog Number: 22-362566). Subsequently, these samples were placed into tubes containing K2E (Catalog Number: 365974), with a bulb used to drain the capillary tube (Catalog Number: 22-362566). The tubes were centrifuged for 15 minutes at 2,000 x g (4°C). The resulting plasma (supernatant) was collected and aliquoted into 1.5ml Eppendorf tubes and stored at -80°C. |
| Sample Type: | Blood (plasma) |
Treatment:
| Treatment ID: | TR003313 |
| Treatment Summary: | All animal procedures were carried out in accordance with the IACUC-approved protocol of Cincinnati Children’s Hospital Medical Center. Animals were monitored daily by Veterinary Services. For subcutaneous tumor implantation, 1x10^6 B16F10 cells were mixed with matrigel 1:1 and implanted subcutaneously into NOD-SCID IL2Rgnull or C57BL/6 mice, respectively. CAY10566 was suspended in 0.5% Methyl Cellulose in water with 0.2% Tween 80 at 9 parts per 1 part DMSO stock. CAY10566 was administered at 30mg/kg via oral gavage, twice daily, with a drug holiday during the weekends. Treatment began three days after tumor cell implantation (bilateral tumors in n=4 per group). Mice were euthanized17 days after tumor cell injection/14 days after the start of treatment. |
Sample Preparation:
| Sampleprep ID: | SP003311 |
| Sampleprep Summary: | For plasma analysis, 20 µL of plasma was aliquoted into 1.5 mL Eppendorf tubes followed by 480 µL cold MeOH. Samples were then vortexed for 30 minutes, insoluble material was pelleted by centrifugation (18000g, 10 min) and supernatants were isolated for analysis by UHPLC-MS. |

| MS Comments: | The Q Exactive was run independently in positive and negative ion mode, scanning using full MS from 125-1500 m/z at 70,000 resolution and top 10 data-dependent MS2 at 17,500 resolution. Electrospray ionization was achieved with 45 Arb sheath gas, 25 Arb auxiliary gas, and 4 kV spray voltage. Calibration was performed prior to the run using the PierceTM Positive and Negative Ion Calibration Solutions (Thermo Fisher Scientific). Run order of samples was randomized and technical replicates were injected after every 4 samples to assess quality control. |
