7-methyl-6-Thioguanosine is a chromophoric substrate that is used to quantify inorganic phosphate (Pi). In the presence of purine nucleoside phosphorylase, it reacts with Pi to produce 7-methyl-6-thioguanine and ribose 1-phosphate, with the increase in 7-methyl-6-thioguanine followed by continuous spectrophotometry at an absorbance of 355-360 nm.{26928} 7-methyl-6-Thioguanosine is also used to measure changes in Pi levels in coupled enzyme systems, including assays of the activities of protein phosphatases, phosphorylase kinases, GTPases, and ATPases.{26928,26932,26930,26931}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 500 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
