SEE ALSO...

SA-2 Antibody (J-12) is a mouse monoclonal IgG1 kappa light chain antibody that detects SA-2 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). SA-2 (J-12) antibody is available in a non-conjugated form, providing flexibility for various experimental needs. SA-2, also known as STAG2, is a crucial 1,231 amino acid component of the cohesion complex, which plays a vital role in ensuring proper segregation of sister chromatids during cell division. SA-2 is localized in the nucleus, where SA-2 associates with chromatin and maintains genomic stability. Upon phosphorylation by polo-like kinase (Plk), SA-2 dissociates from chromatin, facilitating correct separation of chromosomes during anaphase. SA-2 has been shown to enhance tumor necrosis factor alpha (TNFα) activity, suggesting a potential role as a transcriptional regulator, which may have implications in cancer biology and therapeutic strategies. SA-2′s interaction with Rad21 and other components of the cohesion complex underscores SA-2′s importance in cell cycle regulation and chromosomal integrity.

Hi Sir/ Mrs, I am interested in STAG2 antibody, but I do need to know the sequence of the antigen you used to make this antibody because I need it to do matching with STAG2 of dog. I need to know if this human STAG2 is suitable for dog...Thanks a lot.

Asked by: IJLafta
Thank you for your question. The specific antigen used to make this antibody, SA-2 (J-12): sc-81852, is considered proprietary. Please contact our Technical Service Department and we are happy to perform the sequence analysis for you to predict whether or not the antibody may cross-react with STAG2 of dog origin. Please call our European Support office toll-free at 00800 4573 8000, email europe@scbt.com, or contact us by live chat.

I am wondering if you have STAG2 (SA-2) monoclonal antibody that is suitable to be used in IHC of dog tissues.   Thanks D. Inam Lafta

Asked by: I J L
Thank you for your question. This monoclonal antibody, SA-2 Antibody (J-12): sc-81852, has not been tested for reactivity with dog, and we are not aware of any publications citing use of the antibody in this species. Unfortunately, none of our SA-2 antibodies have been tested in, or are currently recommended for detection of the protein in dog tissues.

Do you recommend using this mouse monoclonal SA-2 antibody for staining mouse tissue?

Asked by: cjMara
Thank you for your question. Yes, SA-2 Antibody (J-12): sc-81852 can be used for IF and IHC(P) on mouse tissue. We recommend using our mouse IgG kappa binding protein (m-IgGκ BP) conjugated to Horseradish Peroxidase (HRP): sc-516102 for specific detection of the primary antibody with minimal background.
