Anti-CARM1 (Ab-228) Antibody

Manufactured by Antibodies.com, this affinity-purified rabbit polyclonal reagent is raised against a synthetic peptide corresponding to amino acids 226–230 (V-K-S-N-N) of CARM1, enabling selective detection of total endogenous CARM1 protein (also known as PRMT4). It is supplied at 1.0 mg/mL in phosphate-buffered saline without Mg²⁺ and Ca²⁺ (pH 7.4), containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, and is unconjugated for maximum flexibility in downstream labeling. The 50 µL format is validated for Western blot (WB) and immunofluorescence (ICC/IF) applications and has been confirmed to react with Human, Mouse, and Rat samples. Produced by immunizing rabbits with a KLH-conjugated synthetic peptide and subsequently purified by epitope-specific affinity chromatography, the antibody delivers robust specificity for researchers studying arginine methyltransferase activity, transcriptional coactivation, and chromatin biology. Routine storage at –20 °C is recommended to preserve full activity across multiple freeze–thaw cycles, with short-term use at 4 °C for working aliquots.
