Applications

Our Abpromise guarantee covers the use of ab122619 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/50 - 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF Use a concentration of 1 - 4 µg/ml. The following steps are recommended prior to antibody incubation: cells fixation in ice cold 4% paraformaldehyde pH 7.2-7.3, followed by permeabilization with 0.1% Triton X-100 in PBS for 3x5 minutes.
WB Use at an assay dependent concentration. PubMed: 22383524

Target

  • FunctionNon catalytic subunit of RNase H2, an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. Participates in DNA replication, possibly by mediating the removal of lagging-strand Okazaki fragment RNA primers during DNA replication. Mediates the excision of single ribonucleotides from DNA:RNA duplexes.
  • Tissue specificityWidely expressed.
  • Involvement in diseaseDefects in RNASEH2B are a cause of Aicardi-Goutieres syndrome type 2 (AGS2) [MIM:610181]. A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood.
  • Sequence similaritiesBelongs to the RNase H2 subunit B family.
