SAE1 and SAE2 form heterodimers which take part in the posttranslational modification of proteins (sumoylation). This process regulates protein structure as well as intracellular localization of the target. SAE1/SAE2 may indicate on dermatomyositis (DM) as autoantibodies against those 2 proteins have been found in patients.
SAE1/SAE2 Human Recombinant produced in SF9 is glycosylated, polypeptide chain containing 2 subunits (SAE1 subunit molecular mass is 39kDa & SAE2 subunit molecular mass is 73kDa). The subunits associate to form a complex.
The SAE1/SAE2 is expressed with a -10xHis tag and purified by proprietary chromatographic techniques.
Sf9 insect cells.
SAE1/SAE2 is supplied in 20mM HEPES buffer pH-7.5, 400mM NaCl and 20% glycerol.
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
Avoid multiple freeze-thaw cycles.
Greater than 80.0% as determined by SDS-PAGE.
1. Binds IgG-type human auto-antibodies.
2. Standard ELISA test (checkerboard analysis of positive/negative samples) and immunodot test with positive/negative samples.
Western blot with anti SAE1/SAE2 autoantibody positive sample & Polyclonal anti-SAE1 and anti-SAE2 antibodies.
0.3-0.8 µg/ml (depending on the type of ELISA plate and coating buffer). Suitable for labeling of functional groups.
