General Notes
This product (Catalog No. DPABH-15467) is a rabbit-derived polyclonal antibody raised against human PSMD4. This antibody exhibits cross-reactivity with PSMD4 from mouse and rat. It has been affinity purified by Protein A. The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes one of the non-ATPase subunits of the 19S regulator lid. Pseudogenes have been identified on chromosomes 10 and 21.
DPABH-15467 is suitable for use in Western blot (WB) (1:500–1:2,000), IF (immunofluorescence) (1:50–1:200) applications.
DPABH-15467 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.
