Identifier context
These notes preserve the current catalog identifiers while making their review boundary explicit.
This CAS number is shared by multiple BX Lab catalog records. Confirm the exact salt, counterion, concentration and supplied form when requesting a quote.
The listed InChIKey is retained as an identity reference and does not by itself establish the salt or counterion form named on this page. Confirm the exact supplied form with BX Lab.
Product profile
m7GTP sodium salt is classified as 7-methylated guanosine triphosphate.
m7GTP sodium salt — m7GTP binding to human eukaryotic translation initiation factor 4E was examined in a reported spectroscopic study as a function of pH, temperature and ionic strength.
For m7GTP sodium salt, capping outcome depends on polymerase system, cap-to-NTP ratio, transcript design and purification method.
