1. In Vitro Mutagenesis for Genetic Research

    In Vitro Mutagenesis for Genetic Research
    Scientists and researchers turn to cloned DNA for various breakthrough studies as they provide multiple genetic copies and DNA segments suitable for wide-scale tests. In vitro mutagenesis is one useful application of cloned DNA, where researchers create a mutation in one segment of the target DNA. The cloned DNA is then transferred into a cell or organism and studied, which provides...
  2. IPTG: Frequently Asked Questions and Protocols

    IPTG: Frequently Asked Questions and Protocols
    IPTG is a molecular biology reagent utilized in cloning experiments. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lacoperon. Unlike allolactose, the IPTG sulfur (S) atom creates a chemical bond which is non-hydrolyzable by the cell, preventing the cell from "eating up" or degrading the inductant; therefore the IPTG concentration remains constant.
  3. IPTG Triggers the Transcription of the Lac Operon

    IPTG Triggers the Transcription of the Lac Operon
    Isopropyl β-D-1-thiogalactopyranoside, abbreviated IPTG, is a molecular biology reagent. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon.
