Description

5-Hydroxy-2'-deoxyuridine (5-OHdU) is a major stable oxidation product of 2'-Deoxycytidine. 5-Hydroxy-2'-deoxyuridine can be incorporated into DNA in vitro by DNA polymerase[1].

In Vitro

To study the specificity of nucleotide incorporation opposite 5-hydroxypyrimidines in template DNA, 18- and 45-member oligodeoxyribonucleotides, containing an internal 2'-deoxy-5-hydroxyuridine (5-OHdU) in two different sequence contexts, were used. Translesion synthesis past 2'-deoxy-5-hydroxyuridine (5-OHdU) in both oligonucleotides occurred, but pauses both opposite, and one nucleotide prior to, the modified base in the template is observed. The specificity of nucleotide incorporation opposite 2'-deoxy-5-hydroxyuridine (5-OHdU) in the template is sequence context dependent. In one sequence context, dA is the principal nucleotide incorporated opposite 2'-deoxy-5-hydroxyuridine (5-OHdU). However in a second sequence context, dC is the predominant base incorporated opposite 2'-deoxy-5-hydroxyuridine (5-OHdU). In that same sequence context, dC is also the predominant nucleotide incorporated opposite 2'-deoxy-5-hydroxyuridine (5-OHdU)[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 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2 mg/mL (8.19 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2 mg/mL (8.19 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
