WebInfobox references. Isopropyl β-d-1-thiogalactopyranoside ( IPTG) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator . WebIPTG represents an artificial substrate that helps it bind to the lac repressor which also allows for gene expression to be induced. ONPG is an alternate substrate for lactose that assists us in measuring enzyme activity through color change.

WebAfter 24 h of incubation, 4% paraformaldehyde was fixed and 0.5% Triton X-100 was permeabilized. Subsequently, they were sealed with bovine serum albumin (BSA). Finally, TRITC (Yeasen, Shanghai, China) was used to label the cytoskeleton and DAPI (Solarbio, Beijing, China) to label the nucleus. Images were taken under a fluorescence microscope ...
