1M IPTG

Reference: IPTG-100

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. IPTG is used to induce expression of cloned genes under the control of the lac operon.

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. IPTG is used to induce expression of cloned genes under the control of the lac operon ⁽¹⁾.

Applications

Blue/white colony screening to distinguish recombinant (white) from non-recombinant (blue) colonies ⁽¹⁾

Induction of gene expression under control of the lac promoter

Empirical Formula: C₉H₁₈O₅S

Recommended Storage Condition: -20^oC. We recommend making single-use aliquots to prevent repeated freeze-thaw cycles of IPTG in solution.
