| Product Name | Human Poly (A)-specific ribonuclease PARN (PARN) ELISA Kit |
|---|---|
| Description | Poly A Specific Ribonuclease is a 3'-exoribonuclease, with similarity to the RNase D family of 3'-exonucleases. It prefers poly(A) as the substrate, hence, efficiently degrades poly(A) tails of mRNAs. Exonucleolytic degradation of the poly(A) tail is often the first step in the decay of eukaryotic mRNAs. This protein is also involved in silencing of certain maternal mRNAs during oocyte maturation and early embryonic development, as well as in nonsense-mediated decay (NMD) of mRNAs that contain premature stop codons. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Poly(A)-specific ribonuclease PARN protein appears to be localized in both the nucleus and the cytoplasm. It is not stably associated with polysomes or ribosomal subunits. This assay has high sensitivity and excellent specificity for detection of Human PARN. No significant cross-reactivity or interference between Human PARN and analogues was observed. |
