The three eukaryotic RNA polymerases are complex multisubunit enzymes that play a central role in the transcription of nuclear genes. This gene encodes an essential and highly conserved subunit of RNA polymerase II that is shared by the other two eukaryotic DNA-directed RNA polymerases, I and III. Alternative splicing results in multiple transcript variants of this gene.Store at -20°C or lower. Aliquot to avoid repeated freezing and thawing. *   http://www.creative-diagnostics.com/Anti-POLR2H-PAb-190499-147.htm
