Variant 2 Human LSD1 (also known as KDM1A (lysine (K)-specific demethylase 1A) or AOF2, amine oxidase (flavin containing) domain 2)) GenBank Accession No. NM_015013, a.a. 158-end, MW=77.9 kDa, expressed in an E. coli expression system with N-terminal GST-tag and PreScission Protease site. GST-tag was cleaved after affinity purification.
Specific activity: >=20.6 pmol/min/ug
Immunogen Region
158-end
Tag
none
Formulation
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 1 mM DTT, 1 mM EDTA, 0.05% Tween-20, and 20% glycerol.
Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
Add 50 ul reaction mix (20 mM phosphate buffer, pH 7.4 and LSD1) to microplate wells coated with the histone peptide substrate. Incubate at room temperature for 30 min. Add antibody against demethylated substrate, incubate 1 hr. Then, add secondary HRP-labeled antibody and incubate for 30 minutes. Finally, add HRP chemiluminescent substrates and read luminescence.
Important: If you intend to assess LSD1 activity in an assay that analyzes hydrogen peroxide, such as BPS Catalog #50106 and #50107, please include a request for Peroxidase Rxn Grade LSD1 with your order. Avoid freeze/thaw cycles.
