Application Abreviews Notes
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 20 kDa (predicted molecular weight: 18 kDa).


  • Relevance

    The RNase H2 complex is a heterotrimer composed of the catalytic subunit RNASEH2A and the non-catalytic subunits RNASEH2B and RNASEH2C (Ribonuclease H2 subunit C). Ribonuclease H2 subunit C is the non catalytic subunit of RNase H2, an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. It participates in DNA replication, possibly by mediating the removal of lagging-strand Okazaki fragment RNA primers during DNA replication. Ribonuclease H2 subunit C also mediates the excision of single ribonucleotides from DNA:RNA duplexes.

    Performed under reducing conditions.

    Predicted band size: 18 kDa
    Observed band size: 20 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 45 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 12 minutes

    AGS3 contains a potential phosphorylation site (SwissProt) which may explain its migration at a higher molecular weight (20 kDa) than predicted (18 kDa).

  • IHC image of AGS3 staining in human colon adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab89726, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for WB and for human samples. In the event that a product is not functioning in the tested applications and species cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

I would like to investigate this particular case further for you, and also obtain more information for our quality monitoring records. In order to proceed with this, I have enclosed a technical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily.

I would appreciate if you are also able to provide an image, including molecular weight markers, which would help us to assess the results.

Thank you for your time and cooperation. We look forward to receiving the completed questionnaire.
