Human PRMT8 (protein arginine methyltransferase 8), GenBank Accession No. NM_019854, a.a. 61-394(end) with N-terminal His-FLAG-tag, MW=40.8 kDa, expressed in Sf9 cells using a Baculovirus expression system.
host species: insect
Host species: insect
Host cell line: Sf9
Specific activity: 2.22 pmol/min/ug
Background
Membrane-associated arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and asymmetrical dimethylarginine (aDMA). Able to mono- and dimethylate EWS protein; however its precise role toward EWS remains unclear as it still interacts with fully methylated EWS.
Immunogen Region
61-394(end)
Tag
N-terminal His-FLAG-tags
Formulation
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 80 ug/ml FLAG peptide, 3 mM DTT, 20% glycerol
Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
50 ul reaction mix (20 mM phosphate buffer pH 7.4, 20 uM S-adenosyl methionine, and 1-5 ng methyltransferase PRMT8) added to the wells coated with the substrate. Incubate at RT for 1 hr. Then, add secondary HRP-labeled antibody and incubate 30 min. Finally,add HRP chemiluminescent substrates and read luminesence.
Avoid freeze/thaw cycles.
