Collection:
Collection ID: | CO000574 |
Collection Summary: | Blood samples were collected at 4 and 8 weeks post-STZ injection. Blood was obtained by tail nicking at week 4 and cardiac puncture at week 8, collected into heparin tubes, centrifuged to obtain plasma, and stored at -80oC until used. |
Sample Type: | Blood |
Storage Conditions: | -80 C |
Additives: | Heparin |
Blood Serum Or Plasma: | Plasma |
Treatment:
Treatment ID: | TR000594 |
Treatment Summary: | Type 1 diabetes was induced at age 8 weeks. The mice were fasted for 6 hours prior to being injected with low dose STZ (50 mg/kg body weight) in sodium citrate buffer (10 mmol/L, pH 4.5) daily for 5 days following the protocols described by Tesch and Allen and recommended by the Animal Models of Diabetic Complications Consortium (AMDCC; amdcc.org)1. Control mice were injected with equivalent volumes of the sodium citrate buffer. Diabetes was confirmed by measuring fasting blood glucose levels using a standard glucose meter at 10 days post-STZ injection. Mice with a fasting glucose level ≥280 mg/dL were considered diabetic. STZ-injected mice with a fasting blood glucose of <280 mg/dL (15mmol/L) were culled and eliminated from the study. |
Treatment Compound: | streptozotocin |
Treatment Dose: | 50 mg/kg body weight |
Treatment Doseduration: | daily; 5 days |
Treatment Vehicle: | sodium citrate |
Animal Endp Tissue Coll List: | plasma, urine, kidney tissue |
Sample Preparation:
Sampleprep ID: | SP000587 |
Sampleprep Summary: | Plasma samples were thawed on ice for 30–60 min and vortexed on a multi-tube vortexer for 4 min at 5,000 rpm, followed by centrifugation at room temperature at 16,000 rcf for 4 min. An aliquot of the supernatant was transferred to pre-labeled 1.5 mL low protein-binding microcentrifuge tube to make the individual study sample (40 µL). Another aliquot of supernatant (11 µL) was combined with those from all other plasma samples in a 1.5 mL low protein-binding microcentrifuge tube to make the total pool quality control sample. The total pool quality control sample was aliquoted (40 µL) to make 6 Total Pool Samples and 4 Column Equilibration samples. 132 µL of the total pool quality control sample was added to the total study sample pool to make a pool of kidney, urine, and plasma samples. The total study pool sample was used to prepare 9 Total Study Samples (40 µL) to aid in alignment of the three studies. Of these, 3 total study samples were included in the plasma analysis. Methanol containing the internal standard Tryptophan-d5 (320 µL; 0.0125 mg/ml) was added to all samples, and samples were vortexed on a multiple tube vortexer for 2 min at 5000 rpm followed by centrifugation at 16,000 rcf for 4 min. The supernatants (290 µL) were transferred into new, pre-labeled 2.0 mL low protein-binding microcentrifuge tubes and capped with disposable rubber stoppers. Samples were placed at -80 °C for 1 h and lyophilized for 18 h. Acetonitrile:Water (125 µL; 95:5) was added to each tube and vortex mixed for 10 min at 5000 rpm, followed by centrifugation at room temperature at 16,000 rcf for 4 min. The supernatants were transferred to pre-labeled autosampler vials and 3 µL was injected into SYNAPT G2-Si. |
