Anti-LSM4 Antibody

LSM4 (Like-Sm 4) is an RNA-binding protein that participates in pre-mRNA splicing as a member of the LSm ribonucleoprotein complex, and this rabbit polyclonal reagent from Antibodies.com enables targeted detection of the human, mouse, and rat homologues in both Western blot and immunohistochemistry workflows. Supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a 100 µl aliquot, the unconjugated antibody is suitable for direct conjugation with user-preferred reporter chemistries (HRP, biotin, or fluorophore). The polyclonal formulation broadens epitope coverage relative to a monoclonal reagent, supporting reliable detection of full-length LSM4 across denaturing SDS-PAGE systems and formalin-fixed paraffin-embedded tissue sections. Validated reactivity spans three commonly studied mammalian species, giving labs working on RNA processing, spliceosome assembly, and U snRNP biology a single primary reagent for comparative sample sets. For short-term use, store refrigerated at 4 °C; for longer-term storage, aliquot and freeze, and protect the preparation from repeated freeze-thaw cycles to preserve binding activity.
