SEE ALSO...

Pol III RPC39 Antibody (RPC39) is a mouse monoclonal IgG1 antibody that detects RPC39 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry. RPC39 is a crucial component of RNA polymerase III, which is responsible for synthesizing essential small RNAs, including transfer RNA (tRNA) and 5S ribosomal RNA (rRNA). The proper functioning of RNA polymerase III is vital for protein synthesis and cellular function, as RPC39 ensures the availability of tRNAs necessary for translating mRNA into proteins. Disruptions in RNA polymerase III activity can lead to various diseases, including cancer, highlighting RPC39′s importance in maintaining cellular homeostasis. Anti-RPC39 antibody provides reliable detection and characterization of RPC39, facilitating research into gene expression and implications in health and disease.
