HELIC2 Antibody (G-9) is a mouse monoclonal IgG1 kappa light chain antibody that detects HELIC2 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). HELIC2 (G-9) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. HELIC2 protein, also known as SNRNP200, ASCC3L1, or BRR2, is a 2,136 amino acid protein primarily localized in the nucleus, where HELIC2 plays a crucial role in RNA processing. HELIC2 contains two SEC63 domains, two helicase C-terminal domains, and two helicase ATP-binding domains, which are essential for HELIC2′s function as an RNA helicase. HELIC2 is vital for promoting specific RNA-RNA conformational changes during the second step of RNA splicing, a process critical for proper maturation of mRNA and gene expression regulation. HELIC2 gene is located on human chromosome 2, a region home to over 1,400 genes and constituting nearly 8% of the human genome. Mutations in genes located on chromosome 2, such as ABCA12, have been linked to severe conditions like Harlequin ichthyosis, highlighting the importance of understanding HELIC2′s functions and interactions in cellular processes and disease mechanisms.

Dear, I'd like to know in which clone this Ab was generated. I'll be using this antibody in a Flow experiment (I know it has not been validated for this assay) so I need to know so I can match my isotype control. Thank you in advance!

Asked by: Dries G
Thank you for your question. The isotype is IgG1 and here is more information. https://www.uniprot.org/uniprotkb/O75643/entry

Can HELIC2 (G-9): sc-393170 monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

Asked by: Professor Griffin
Thank you for your question. Yes, HELIC2 (G-9): sc-393170 has been validated for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
