Key elements and design rationale
- Target: USP22 (kallikrein-related peptidase 2). Alternative names: Kallikrein-2; Glandular kallikrein-1; hGK-1; Tissue kallikrein-2; KLK2;
- Antibody format: Polyclonal; Rabbit IgG
- Species context: Host: Rabbit, Reactivity: Human,Mouse,Rat
- Purification: Immunogen affinity purified.
- Immunogen: A synthetic peptide corresponding to a sequence at the N-terminus of human USP22, which shares 89.5% amino acid (aa) sequence identity with mouse USP22.
- Molecular weight context: observed 68 kDa (reported)
- Provided application(s): WB, IHC, Flow, ELISA
These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.
Biological background
Function: Glandular kallikreins cleave Met-Lys and Arg-Ser bonds in kininogen to release Lys-bradykinin.
Background: Ubiquitin specific peptidase 22 is a protein that in humans is encoded by the USP22 gene on chromosome 17. Enables enzyme binding activity; nuclear receptor coactivator activity; and thiol-dependent deubiquitinase. Contributes to H4 histone acetyltransferase activity. Involved in positive regulation of mitotic cell cycle; positive regulation of transcription, DNA-templated; and protein modification by small protein conjugation or removal. Part of SAGA complex.
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
