DNA labeling scheme for the DNA fiber analysis. Cells were consecutively treated with 5-iodo-2′-deoxyuridine (IdU) and 5-Chloro-2'-deoxyuridine (CldU) (80 μM; 30 min). Both pulses were exactly 30 min and ethanol (EtOH) or MMS was added during the second pulse only. The ratio of IdU/CldU track length is depicted. For each condition, four independent biological replicates were assessed, with a minimum of 150 fibers each. Each dot corresponds to a measurement of an individual DNA fiber, the black bar represents the average IdU/CldU ratio. The fold change with respect to the control is also indicated on the graph. Number of scored fibers: Control = 990; MMS = 520; EtOH 100 mM = 549; EtOH 250 mM = 607; EtOH 400 mM = 616.

In Vitro

When 5-Chloro-2’-deoxyuridine (ClDU) is placed into tissue culture medium, mammalian cells incorporate the analog into DNA. It is observed that 10 μM concentration of 5-Chloro-2’-deoxyuridine in the media does not alter cell division kinetics. Previously it has been shown that 5-Chloro-2’-deoxyuridine is metabolized and incorporated into DNA using antibodies that bind selectively to DNA containing halogenated bases. In the studies reported here, 5-Chloro-2’-deoxyuridine is more similar to BrdU in acting as a T analog. The toxicity of 5-Chloro-2’-deoxyuridine could in part be attributed to inhibition of thymidylate synthase^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.08 mg/mL (7.92 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Cell Assay	Human erythroleukemia K-562 cells are used throughout the study. Cells are initially seeded at 1.0×10⁵ cells/mL and treated with either 10 μM 5-Chloro-2’-deoxyuridine or 10 μM thymidine (negative control) for 63 h, or two cell doublings. Cells are counted by trypan blue exclusion, pelleted by centrifugation (500×g) and washed with 10 mL sterile PBS^[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration ^[2]	Rats^[2] Adult, male Wistar rats, weighing 200-250 g are used. Firstly, the animals are allowed to self-administer methamphetamine at a dose of 0.05 mg/kg/injection under a fixed-ratio 1 (FR1) schedule for baseline sessions. After that, the rats are divided into four groups. Two groups of rats (long-access; LgA-4 days (d), LgA-13 d; n=7 per group) are allowed to self-administer 0.05 mg/kg/injection of methamphetamine for 6 h per day, whereas the other groups (short-access; ShA-4 d, ShA-13 d; n=7 per group) are allowed to do so for 1 h per day. All procedures are performed during the dark cycle. On day 5, ShA-4 d and LgA-4 d rats receive one injection of 50 mg/kg 5-chloro-2’-deoxyuridine and survive for 30 min. On day 14, ShA-13 d and LgA-13 d receive one injection of 50 mg/kg 5-Iodo-2’-deoxyuridine followed by 50 mg/kg 5-chloro-2’-deoxyuridine 2 h later. These rats also survive for 30 min after the 5-Chloro-2'-deoxyuridine injection. A parallel group of drug-naive rats (n=6) receive one injection of 50 mg/kg IdU followed by 50 mg/kg 5-Chloro-2'-deoxyuridine 2 h later. These rats also survive for 30 min after the 5-Chloro-2'-deoxyuridine injection^[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
