    Melittin purchased from MCE. Usage Cited in: J Pharm Pharmacol. 2023 Mar 26;rgad008.  [Abstract]

    Melittin (2.5, 5, 10 μg/mL; 48 h) downregulates the expression of Bcl-2, and increases the levels of the pro-apoptotic molecules Bax and cyt-c, in SW480 cells.

    生物活性

    Melittin is a PLA2 activator, stimulates the activity of the low molecular weight PLA2, while it does not the increase activity of the high molecular weight PLA2[1][2].

    IC50 & Target

    PLA2[1]
    体外研究
    (In Vitro)

    Melittin, an immunologically related PLA2 stimulating peptide from bee venom, increases the activity of the high molecular weight enzyme[1]. Melittin is a cytotoxic peptide from bee venom. Melittin exhibits toxicity against both A2780CR and A2780 cells, with IC50 values of 4.5 and 6.8 μg/mL, respectively. Melittin has natural anti-bacterial, anti-viral, and anti-inflammatory properties. It has also been shown to have diverse anticancer effects in several different cancer cell lines including those of gastric, breast, ovarian, liver, prostate, cervical, and lung origins. The mechanisms by which Melittin, an amphipathic haemolytic peptide, exerts its potential anticancer effects include inhibition of cell proliferation, induction of apoptosis, and direct necrosis. Melittin can also prevent EGF-induced cell invasion through its inhibition of the PI3K/Akt/mTOR signaling pathway, but this is primarily related to breast cancer cells[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Cell Assay
    [2]

    Melittin is purified from bee venom by reversed phase liquid chromatography and reconstituted in sterile water to form a stock solution of 1 mg/mL before storage at -20 °C until required for analysis. Cell viability is assessed by an Alamar Blue (AB) cell viability reagent. Both A2780 and A2780CR cells are seeded at 1×104 cells/well in 96-well plates and incubated at 37 °C and 5% CO2 in a humidified atmosphere for 24 h. After this incubation period, the cells are treated with various concentrations of Melittin ranging from 0.5 to 14 µg/mL in 100 μL of medium, and re-incubated at 37 °C and 5% CO2 for a further 24 h. Triton X at 1% (v/v) and cell culture media are used as positive and negative controls, respectively. After this, AB is added at a final concentration of 10% (v/v) and the resultant mixture is incubated for a further 4 h at 37 °C and 5% CO2. Then, the plates are read at an excitation wavelength of 560 nm and the emission at 590 nm is recorded on a SpectraMax M3 microplate reader . Background-corrected fluorescence readings are converted to cell viability data for each test well by expressing them as percentages relative to the mean negative control value[2].

    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.
