Handling Instructions Technical Support

N-(3-Oxohexanoyl)-L-homoserine lactone (OHHL; N-(3-Oxohexanoyl)homoserine lactone) is a specific agonist of LuxR-type transcription factor CarR with a Kd of 1.8 μM. N-(3-Oxohexanoyl)-L-homoserine lactone activates CarR by inducing protein multimerization, promoting its binding to target DNA sequences in the carR-carA intergenic region, thereby upregulating the transcription of carbapenem biosynthesis genes. N-(3-Oxohexanoyl)-L-homoserine lactone acts as a quorum sensing signal molecule, enabling bacteria to coordinate the production of carbapenem antibiotics in a cell density-dependent manner. N-(3-Oxohexanoyl)-L-homoserine lactone is used to study bacterial quorum sensing mechanisms, especially the secondary metabolism and virulence factor regulatory pathways of Erwinia carotovora and Yersinia enterocolitica.

N-(3-Oxohexanoyl)-L-homoserine lactone activates CarR by inducing protein multimerization, promoting its binding to target DNA sequences in the carR-carA intergenic region, thereby upregulating the transcription of carbapenem biosynthesis genes.

N-(3-Oxohexanoyl)-L-homoserine lactone is used to study bacterial quorum sensing mechanisms, especially the secondary metabolism and virulence factor regulatory pathways of Erwinia carotovora and Yersinia enterocolitica[1][2][3].

In Vitro

N-(3-Oxohexanoyl)-L-homoserine lactone (3-oxo-C6-HSL) (25 μM; 5 h) significantly enhances the resistance of CarR protein to trypsin in limited protease digestion experiments[1].
N-(3-Oxohexanoyl)-L-homoserine lactone (73.3 μM; 1 h) induces CarR to form a high molecular weight complex with target DNA and enhanced the binding efficiency[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: ≥ 2.5 mg/mL (11.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (11.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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.
