IPTG, dioxan free 7757-83-7 Trifluoromethanesulfonic anhydride (CAS number 358-23-6)

Trifluoromethanesulfonic anhydride (CAS number 358-23-6)

This lack of interference occurs because steric hindrance of the protonated tertiary amine in HEPES shields the negative charge of DNA to a lesser extent than less substituted buffers

due to its high conformational propensity to form a six-membered ring with an internal disulfide bond when oxidised

They are cellulose based providing high purity but will weaken when wet

It is a component of Ultramark 1621

IPTG, dioxan free 7757-83-7 Trifluoromethanesulfonic anhydride (CAS number 358-23-6)IPTG is an analog of galactose that is non metabolizable and inactivates the lac repressor to induce synthesis of galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG is commonly used in cloning procedures that require induction of galactosidase and is most often used with
