    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing.

ターゲット情報

  • 機能

    Cleavable component of the cohesin complex, involved in chromosome cohesion during cell cycle, in DNA repair, and in apoptosis. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At metaphase-anaphase transition, this protein is cleaved by separase/ESPL1 and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis. Also plays a role in apoptosis, via its cleavage by caspase-3/CASP3 or caspase-7/CASP7 during early steps of apoptosis: the C-terminal 64 kDa cleavage product may act as a nuclear signal to initiate cytoplasmic events involved in the apoptotic pathway.

  • 配列類似性

    Belongs to the rad21 family.

  • ドメイン

    The C-terminal part associates with the head of SMC1A, while the N-terminal part binds to the head of SMC3.

  • 翻訳後修飾

    Cleaved by separase/ESPL1 at the onset of anaphase. Cleaved by caspase-3 and caspase-7 at the beginning of apoptosis. The cleavage by ESPL1 and caspase-3 take place at different sites.
    Phosphorylated; becomes hyperphosphorylated in M phase of cell cycle. The large dissociation of cohesin from chromosome arms during prophase may be partly due to its phosphorylation by PLK.

  • 細胞内局在

    Nucleus. Chromosome. Chromosome > centromere. Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin probably because of phosphorylation by PLK, except at centromeres, where cohesin complexes remain. At anaphase, it is cleaved by separase/ESPL1, leading to the dissociation of the complex from chromosomes, allowing chromosome separation. Once cleaved by caspase-3, the C-terminal 64 kDa cleavage product translocates to the cytoplasm, where it may trigger apoptosis.

Question

Customer kindly contacted us regarding positve and negative primers for our ChIP grade antibodies.

Answer

I've compiled some information below regarding potential primer sets for the ChIP antibodies we talked about, where information was lacking (verified in ChIP by other researches), I included links to abReviews and references that used the antibody in ChIP.

1. ab817: GAPDH (+), GAD1 (-), AFM (-), Factor VIII (-)

2. ab1791: GAPDH, RPL30, ALDOA, MYO-D, SERPINA, AFM, SAT2, SATa (each batch is verified against this primer set, an example image of one batch test is given on the datasheet)

3. ab7030: was verified in ChIP by other researchers submitting data through our abReview system and specific references. Their positive and negative controls used are given through the link below, as well as a "click to contact this user" link that allows you to contact the researchers if you would like more specific primer information. The specific references with ChIP listed in bold are good sources for positive and negative primers as well.
