    Objective:

    Measure the fluorescence intensity in arsenic solution and Chinese medicine

    Material:

    DH5α arsenic plasmid (ctrl) on LB agar plates

    SOC broth

    Chloramphenicol(1000 X)

    15 ml tube, 50 ml tube

    96 well plate

    Procedure:

    Rpm 120:

    　1.Culture 3 tubes of 2ml E. coli overnight by 15ml centrifuge tubes (2ml SOC, 2ul Chloramphenicol)

    　2.Put them to the same tube at the next day, then add 6ml of SOC broth(water bath 37°C for 5 min. before use)and 12ul Chloramphenicol for a 2-fold dilution.

    　3.Take 5ml SOC broth for to a 15ml centrifuge tube for blank

    　4.Aliquot the bacterial broth into six 15ml centrifuge tubes (2ml for each), then culture for 2 hours

    　5.Measure OD 595

    　6.Dilute to OD 0.5. More than 12ml


    Rpm 80:

    　1.100, 50, 30, 10, 1ppm arsenic solutions, use ddH2O in control group

    　2.Dilute the E. coli broth to 50-fold by SOC broth (0.6ml E. coli broth+0.3ml Arsenic solutuin+9ul Chinese medicine stock+30ul CP 29.1ml SOC broth）

    　3.Measure it's fluorescence intensity and OD at 0min. measure every 30 min. Blank is needed every time.


    Arsenic solution preparation:

    　100ppm: 104 As solution 0.3ml

    　50ppm: 104 As solution 0.15ml + ddH2O 0.15ml

    　30ppm: 104 As solution 0.09ml + ddH2O 0.21ml

    　10ppm: 103 As solution 0.3ml

    　1ppm: 102 As solution 0.3ml


    Results:

    Fluorescence intensity in Licorice with arsenic.

    Fluorescence intensity in Angelica with arsenic.

    Fluorescence intensity in Mint with arsenic.

    Fluorescence intensity in Modified Ease Powder with arsenic.

    In chinese medicine, E.coli expresses stronger fluorescence in a higher arsenic concentration.
