Thermostable TDG Protein and 10X REC™ Buffer 4


TDG is a thermostable thymine DNA glycosylase from Methanobacterium thermoautotrophicum. The optimal temperature for the enzyme is 65°C. The enzyme lacks significant AP lyase or endonuclease activity. TDG works effectively in heteroduplex analysis to detect C to T transitions.

Available Size(s): 500 units, 1ml Catalog Number: 4070-500-EB Category:


500 units per vial
Purified from E.  coli containing a recombinant plasmid harboring the Methanobacterium thermoautotrophicum TDG gene.
Recognizes T/G mismatches in duplex DNA and cleaves the strand with the T. Also, recognizes G/G mismatches if at least one nearest neighbor is an A or T and nicks one strand or the other.
Store at -20°C in a manual defrost freezer. For long-term storage, freeze at -80°C in working aliquots.
