Corticosterone EIA Kit from IDS Ltd

Description:... in varying proportions. It is therefore critical to look at relative cross-reactivities of these closely related steroids (differing by only one hydroxyl group at C17) if attempting to differentiate between them by immunoassay. Our assay has a low 0.02% cross-reactivity with ....

T4 DNA Ligase from Invitrogen

Description:... T4 DNA Ligase catalyzes the formation of phosphodiester bonds in the presence of ATP between double-stranded DNAs with 3' hydroxyl and 5' phosphate termini. The unique T4 DNA Ligase buffer optimizes ligation which can be performed in 5 minutes (1). Single-stranded nucleic acids ...

ARCA (Anti Reverse Cap Analog) from Ambion

Description:... 3 OH group (closer to m7G) is replaced with OCH3. Because of this substitution, the RNA polymerase can only initiate transcription with the remaining hydroxyl group thus forcing ARCA incorporation in the forward orientation. As a result, unlike transcripts synthesized with conventional cap analog, 100% of ...
