Product Overview
This rabbit polyclonal antibody recognizes polyribonucleotide nucleotidyltransferase 1, mitochondrial (gene PNPT1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 86.0 kDa, and the supplier reports an observed band at about 86 kDa.
Polynucleotide phosphorylase (PNPase, PNPT1) is a 3′-to-5′ exoribonuclease found mainly in the mitochondrial intermembrane space. It helps degrade and process mitochondrial RNAs, contributes to mitochondrial mRNA polyadenylation, and has been implicated in importing certain small RNAs into mitochondria. PNPT1 is studied in mitochondrial gene expression and RNA turnover.

Immunogen
Recombinant human PNPT1 fragment (Met1–Gln257), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places polyribonucleotide nucleotidyltransferase 1, mitochondrial in the cytoplasm, mitochondrion matrix and mitochondrion intermembrane space. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
