Product Overview
Clone 26S89 is a rabbit monoclonal antibody that recognizes U2 small nuclear ribonucleoprotein A' (gene SNRPA1) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 28.4 kDa, and the supplier reports an observed band at about 28 kDa.
U2A′ (SNRPA1) is a component of the U2 snRNP of the spliceosome, where it helps bind stem loop IV of U2 snRNA. It is needed for pre-mRNA splicing.

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).
