Handling Instructions Technical Support

3-Methyluridine (m³U; N3-Methyluridine) is a methylated nucleotide present in ribosomal RNA (rRNA), mainly targeting specific base sites of RNA molecules such as 23S rRNA. 3-Methyluridine can introduce a methyl group at the N3 position of uracil, affecting the secondary structure stability and base pairing ability of RNA, and regulating ribosome function. For example, it affects ribosomal subunit binding and tRNA interaction. 3-Methyluridine is often used as a key raw material for the synthesis of modified nucleotides, and is used to construct RNA oligonucleotides containing methylation modifications to study the effects of RNA methylation on gene expression and drug resistance.

Description

IC₅₀ & Target

Human Endogenous Metabolite

In Vitro

1. Single-cell methylation detection experiment:
3-Methyluridine (probe concentration 1 μM; ≥4.5 h) significantly distinguishes wild-type Escherichia coli containing methylated rRNA from mutants lacking KsgA methyltransferase through methylation-sensitive fluorescence in situ hybridization (MR-FISH) technology, showing the inhibitory effect of single methylation sites on probe binding^[1].
2. RNA structure and stability analysis experiment:
3-Methyluridine (5-200 μM; thermal melting analysis time 48-72 h) in RNA hairpins containing the 1920-loop region, N3 methylation has a negligible effect on RNA thermodynamic stability and does not change its A-form conformation, which is similar to the effect of unmodified uridine^[2].

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: ≥ 2.67 mg/mL (10.34 mM); Clear solution

This protocol yields a clear solution of ≥ 2.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (26.7 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: ≥ 2.67 mg/mL (10.34 mM); Clear solution

This protocol yields a clear solution of ≥ 2.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (26.7 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.67 mg/mL (10.34 mM); Clear solution

This protocol yields a clear solution of ≥ 2.67 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (26.7 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
