    Description
    IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. The IPTG is used to induce the expression of cloned genes which are under control of the lac operon. It is used in conjunction with X-Gal to determine the lac phenotype in blue/white colony screening.
    Applications
    •Blue/white colony screening, see Protocol for the Blue/White Colony Screening.
    •Induces the expression of cloned genes that are under control of the lac promoter.
    Quality Control
    Dioxane-free.
    Greater than 99% purity confirmed by HPLC.
    Functionally tested in blue/white colony screening.
    Note
    •Preparation of a 23.83 mg/ml (100 mM) stock solution of IPTG in water is recommended.
    •For blue/white screening, 0.1 mM final IPTG concentration in LB (Luria Broth) media is recommended.
    Protocol for the Blue/White Colony Screening
    For individual LB (Luria Broth) agar plates:
    1.Pour sterile warm LB agar (about 25 ml) into a Petri dish.
    2.Dry opened LB plates at room temperature under UV light for about 30 min.
    3.Add 40 µl of the X-Gal Solution (20 mg/ml), ready-to-use.
    4.Add 40 µl of 100 mM IPTG Solution, ready-to-use.
    5.Spread evenly on the plate with a sterile spatula.
    For batch use, add the following directly per 1 ml of the liquid LB agar (kept at about 50°C):
    1.1 µl of X-Gal Solution (20 mg/ml), ready-to-use.
    2.1 µl of 100 mM IPTG Solution, ready-to-use.
    3.Mix well.
    4.Pour 25 ml of prepared LB agar into each Petri dish.
    5.Dry opened LB plates at room temperature under UV light for about 30 min.
