Product Overview
This rabbit polyclonal antibody detects 5'-3' exoribonuclease 2 (gene XRN2) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 108.6 kDa, and the supplier reports an observed band at about 109 kDa.
XRN2 is a nuclear 5′–3′ exoribonuclease with roles in RNA processing and degradation. After cleavage at the poly(A) site, it degrades the downstream RNA still attached to RNA polymerase II and helps release the polymerase, a model of transcription termination known as the torpedo mechanism; it also contributes to rRNA and other RNA processing.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
