Iptg light sensitive
WebMay 30, 2012 · I’m trying to make RNAi work on my bench, so far no positive phenotype observed… I’m using N2 and unc-22, dpy-6 etc. so my guess is that the antibiotics or IPTG went wrong. And I just read some papers saying that IPTG is light-sensitive and should be kept in dark. How does this work when they’re getting seeded? WebIPTG. IPTG is an analog of galactose that is nonmetabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. IPTG is often used in the induction of recombinant proteins, is a substrate for thigalactoside transacetylase ...

WebAlthough less sensitive than X-Gal assays, liquid β-galactosidase assays using o-nitrophenyl-β-d-galactopyranoside (ONPG) provide a more quantitative estimate of lacZ reporter gene activity. 1. Inoculate colonies to be assayed (in triplicate) into 2 ml of noninducing, selective medium and grow for 14-18 hr at 30°, with shaking. 2. WebMar 2, 2012 · Plasmids pDusk for light-repressed and pDawn for light-activated gene expression in E. coli. In pDusk, the engineered TCS YF1/FixJ drives gene expression from the pFixK2 promoter in a blue-light-repressed fashion. Insertion of the λ phage repressor cI and the λ promoter pR in pDawn inverts signal polarity and renders gene expression light ...
WebX-gal should be made up in dimethyl formamide and stored in the freezer - the tubes are often wrapped with foil since the X-gal is light sensitive. Just before plating the transformed cells, add 10 ul of 100 mM IPTG to the cell mix. IPTG also stored in the freezer.
