General Notes
This product (Catalog No. DPABH-28068) is a rabbit-derived polyclonal antibody raised against human MSRB1. This antibody exhibits cross-reactivity with MSRB1 from mouse and rat. It has been affinity purified by Protein A. The protein encoded by this gene belongs to the methionine-R-sulfoxide reductase B (MsrB) family. Members of this family function as repair enzymes that protect proteins from oxidative stress by catalyzing the reduction of methionine-R-sulfoxides to methionines. This protein is highly expressed in liver and kidney, and is localized to the nucleus and cytosol. It is the only member of the MsrB family that is a selenoprotein, containing a selenocysteine (Sec) residue at its active site. It also has the highest methionine-R-sulfoxide reductase activity compared to other members containing cysteine in place of Sec. Sec is encoded by the UGA codon, which normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. A pseudogene of this locus has been identified on chromosome 19.
DPABH-28068 is suitable for use in Western blot (WB) (1:500–1:2,000), IHC (1:100–1:500), IF/ICC 1 (50-1:100) applications.
DPABH-28068 is supplied as a liquid formulation in PBS with 0.02% sodium azide,50% glycerol,pH7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
