Anti-Histone H3 Antibody

Affinity-purified rabbit polyclonal reagent from Antibodies.com that recognizes the mono-methylated lysine 37 residue on Histone H3, a post-translational modification widely investigated in chromatin biology and epigenetic regulation. The unconjugated antibody is supplied as a 50 µl vial at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.3. Validated for Western blot workflows, it specifically detects Histone H3 in Human, Mouse, and Rat samples, supporting comparative studies of histone methylation patterns across species. Typical use cases include probing acid-extracted histone fractions, characterizing chromatin-modifying enzyme activity, and tracking H3K37 methylation changes in response to drug treatment or differentiation cues. For optimal stability, store at -20°C in working aliquots to limit freeze-thaw cycles, and avoid prolonged exposure to light.
