This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Selenophosphate synthetase (SelD) catalyzes the conversion of selenium to selenophosphate which is required by a number of bacterial, archaeal and eukaryotic organisms for synthesis of selenocysteine-tRNA, the precursor of selenocysteine in selenoenzymes.  A second selenophosphate synthetase (SPS2) was identified in mammals. SPS2 is itself a selenoprotein in mammals.

Application Note

This Protein A purified antibody has been tested for use in ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 48 kDa in size corresponding to SPS2 by western blotting in the appropriate cell lysate or extract.


This product was purified by Protein A chromatography from monospecific antiserum.  This antibody reacts with mouse SPS2 and shows partial cross-reactivity with SPS1.  A BLAST analysis was used to suggest cross-reactivity with SPS2 from human sources based on an 84% homology with the immunizing sequence.  Cross-reactivity with SPS2 from other sources has not been determined.
