Anti-Selenophosphate Synthetase 2 SEPHS2 Antibody

This antibody 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.

This Protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a full-length recombinant protein corresponding to mouse SPS2.

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.

Store vial at -20°C prior to opening. Aliquot contents and freeze at -20°C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use. Expiration date is one (1) year from date of opening.

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.
