    Concentration: 0.01, 0.1, 1 or 10 µg/mL
    Incubation Time: 4 days
    Result: Affected growth of glioma cells only under high concentrations (10 µg/mL).

    Cell Viability Assay[2]

    Cell Line: SVG cells
    Concentration: 0.01, 0.1, 1 or 10 µg/mL
    Incubation Time: 24 hours
    Result: Decreaseed MT-CO1 protein content with concentrations of 1 µg/mL and higher.

    Cell Proliferation Assay[4]

    Cell Line: MCF 12A, 293T cells
    Concentration: 100 ng/mL, 1 µg/mL
    Incubation Time: 96 hours
    Result: Caused reduced proliferation of MCF 12A and 293T cells at 1 µg/mL.

    Cell Viability Assay[5]

    Cell Line: MCF-7, MDA-MB-468 cells
    Concentration: 0-250 μM
    Incubation Time: 72 hours

    In Vivo

    Doxycycline (oral gavage; 200 or 800 mg/kg; once daily; 3 months) reduces MMP-9 activity in untreated HT mice in a dose-dependent manner[3].
    Doxycycline and Tetracycline (HY-A0107), act systemically after absorption from the upper gastrointestinal tract. The main advantage of Doxycycline over Tetracycline is its longer activity, and it can be taken twice or once a day. The peak concentration of both drugs is similar, but in the case of Doxycycline the time to peak concentration is shorter, and half life is significantly longer[6].

    Doxycycline (Dox) is often used as an inducer in molecular biology studies to induce gene expression. In cells or model animals that have constructed tetracycline induced expression systems (Tet-On/Tet-Off systems), the expression of target genes can be precisely controlled by adding or removing Dox[7][8][9][10].

    Dose reference for Dox induction[7][8][9][10]:
    (1) Model animal: male Sprague–Dawley rats
    Tet regulatory system:20-3000 ppm of Dox is supplied in diet
    (2) Model animal: Cags mice
    Tet regulatory system:625 ppm of Dox is supplied in diet
    (3) Model animal: Transgenic Wistar rats
    Tet regulatory system:2 mg/mL of Dox is supplied in drinking water
    (4) Model animal: Transgenic NRMI inbred mice
    Tet regulatory system:2 mg/mL of Dox is supplied in drinking water

    Dissolution method of Dox[9][10]:
    (1) Prepare Dox working solution
    Dissolve 100 mg Dox into 50 mL drinking water, add 5% sucrose or 2% saccharin to mask the bitter taste, and refresh the water every three days.

    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.
