Anti-Histone H3 (L20) Antibody

A polyclonal reagent from Antibodies.com targets Histone H3, a core nucleosomal protein whose lysine and arginine residues carry post-translational marks tied to chromatin state and transcription. Supplied as 100 µl at 1 mg/ml in phosphate buffered saline (pH ~7.2) with 0.05% sodium azide, this unconjugated antibody is validated for Western blot and immunohistochemistry workflows on human, mouse, and rat samples. In WB it functions as a chromatin-loading reference alongside modified-H3 probes, while in IHC it highlights nuclear staining patterns across fixed tissue sections. Researchers studying epigenetic regulation or chromatin remodeling will find this polyclonal antibody useful as a pan-H3 anchor in multiplexed immunoblots and as a counterstain in modified-H3 imaging studies. Aliquot upon receipt to limit freeze-thaw cycles; the sodium azide-containing PBS serves as a preservative, and the reagent should be handled with standard cold-chain precautions typical for polyclonal sera.
