SKU:: 338140
Purity:: Purified by Protein G affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Recombinant human Trimethylguanosine synthase protein(713-853AA)
Format:: Supplied as a liquid in 0.01M PBS, pH 7.4, 0.03% Proclin 300, 50% glycerol.
Extra Details:: Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m7G) caps of snRNAs and snoRNAs to a 2,2,7-trimethylguanosine (m(2,2,7)G) cap structure. The enzyme is specific for guanine, and N7 methylation must precede N2 methylation. Hypermethylation of the m7G cap of U snRNAs leads to their concentration in nuclear foci, their colocalization with coilin and the formation of canonical Cajal bodies (CBs). Plays a role in transcriptional regulation. Applications: Suitable for use in ELISA and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry: 1:20-1:200 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
