Product Overview
This rabbit polyclonal antibody detects ribonuclease H2 subunit B (gene RNASEH2B) in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 35.1 kDa, and the supplier reports an observed band at about 35 kDa.
RNASEH2B is a non-catalytic subunit of RNase H2, the complex that removes ribonucleotides embedded in genomic DNA and degrades RNA in RNA:DNA hybrids. It is needed for proper assembly and function of the enzyme, and mutations in RNASEH2B are a common cause of Aicardi–Goutières syndrome, a type I interferon disorder.

Immunogen
Recombinant human RNASEH2B fragment (Lys39–Glu260), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ribonuclease H2 subunit B in the nucleus. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
