Human PSMB11 ELISA Kit (HUFI07009)

Quantify the β5t proteasome catalytic subunit in human serum specimens, K2-EDTA plasma aliquots, and lithium-heparin plasma samples with this Assay Genie ELISA Kit. PSMB11 is a specialized chymotrypsin-like component of the thymoproteasome, expressed predominantly by cortical thymic epithelial cells, where it shapes the MHC class I peptide repertoire presented to developing T cells during positive selection in the thymus.

The microplate ships as a complete reagent set with pre-coated wells, biotinylated detection antibody, recombinant protein standards, streptavidin-HRP conjugate, TMB substrate solution, stop reagent, and concentrated wash buffer, providing enough material for a full 96 Assays plate layout. Researchers investigating autoimmune disease mechanisms, age-related thymic involution, or antigen processing pathways apply this assay to measure PSMB11 abundance as a quantitative indicator of thymic epithelial integrity and T-cell repertoire selection.

Storage and handling: keep the sealed kit refrigerated between uses and protect from light; reconstituted standards should be aliquoted and frozen to limit repeated freeze-thaw cycles. Intended for research use only and not validated for diagnostic procedures.
