Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E. coli-derived human CUL2 recombinant protein (Position: E389-A745). (reported region: E389-A745).
• Molecular weight context: reported MW: 87 kDa; calculated MW: 86,983 MW
• Reactivity: Human,Mouse,Rat
• Applications: ELISA, Flow Cytometry, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

Aldo-keto reductase family 1 member B10; cullin 2. Cullin 2 (CUL2) is a protein that in humans is encoded by the CUL2 gene. Using immunofluorescence, it is showed that CUL2 is a cytosolic protein that can be translocated to the nucleus by VHL. By fluorescence in situ hybridization, this gene is mapped to 10p11.2-p11.1, a region reported to show loss of heterozygosity (LOH) in several forms of human cancer, including non-clear cell renal cell carcinoma. CUL2 may serve as a rigid scaffold in the complex and may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. Functional note: Core component of multiple cullin-RING-based ECS (ElonginB/C-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination of target proteins. ECS complexes and ARIH1 collaborate in tandem to mediate ubiquitination of target proteins (PubMed:27565346). May serve as a rigid scaffold in the complex and may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The E3 ubiquitin-protein ligase activity of the complex is dependent on the neddylation of the cullin subunit and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1. The functional specificity of the ECS complex depends on the substrate recognition component. ECS (VHL) mediates the ubiquitination of hypoxia-inducible factor (HIF). Reported localization: Cell membrane. Multi-pass membrane protein. Expression/tissue context: Expressed by CD133-expressing progenitor cells among epidermal melanocytes (at protein level). Widely expressed with specific expression in pigment cells. Highly expressed in several malignant tissues: highly expressed in clinical melanomas, with low expression in normal skin. In melanoma, marks malignant melanoma-initiating cells (MMIC), in which clinical virulence resides as a consequence of unlimited self-renewal capacity, resulting in inexorable tumor progression and metastasis. Also highly expressed in a number of leukemia cells. Expressed in basal limbal epithelium.

Common research applications

• Western blotting: compare relative CUL2 (Aldo-keto reductase family 1 member B10) levels across conditions; band patterns may reflect isoforms and processing.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
• ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
