ARNA-3 is excellent for detection of transcription activity, e.g. puffs in polytene chromosomes. Reacts with RNA polymerase II (Mr 175,000 subunit of RNAP II) in biological materials. Reactive polypeptides after SDS-PAGE: 200 kD band of nonphosphorylated and 240 kD band of phosphorylated Pol IIA.
Epitope recognized within: 794-DDYGPESRGFVENSYLA-822
