Recombinant Ubiquitin Antibody

Overview

Ubiquitin is a highly conserved and plays an essential role in the ubiquitin-proteasome pathway. In ubiquitination process, it is first activated by forming a thiol-ester complex with the activation component E1, which is then transferred to ubiquitin-carrier protein E2, followed by to ubiquitin ligase E3 for final delivery to epsilon-NH2 of the target protein lysine residue. IkB, p53, cdc25A, Bcl-2 etc. are shown as targets of ubiquitin-proteasome process as part of regulation of cell cycle progression, differentiation, cell stress response, and apoptosis. Moreover, ubiquitin have been reported to bind covalently with pathological inclusions which are resistant to degradation e.g. neurofibrillary tangles/paired helical filaments in Alzheimer's disease, Lewy bodies seen in Parkinson's disease, and Pick bodies found in Pick's disease etc.

This anti-Ubiquitin antibody is supplied as Purified (Rabbit, Recombinant Rabbit Monoclonal, clone UBB/3143R, Rabbit IgG, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.

Key elements and design rationale

• Target: Ubiquitin
• Format: Purified
• Localization: Cytoplasmic, nuclear, cell surface
• Species reactivity: Human
• Applications (listed): IHC-P, WB
• Conjugate: Unconjugated
• Clone and antibody class: Recombinant Rabbit Monoclonal, clone UBB/3143R, Rabbit IgG

Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.

Biological background

Ubiquitin is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.

Research relevance and current trends

• Profiling Ubiquitin expression across model systems, perturbations, and time points to support mechanistic hypotheses.
• Combining antibody-based detection with multi-omics or imaging readouts to link Ubiquitin signal with phenotype.
• Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.

Common research applications

• IHC-P
• WB

Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.

Notes for experimental interpretation

• Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
• Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
• Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.
