靶标

  • 功能Component of heterochromatin. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Interaction with lamin B receptor (LBR) can contribute to the association of the heterochromatin with the inner nuclear membrane.
  • 组织特异性Expressed in all adult and embryonic tissues.
  • 序列相似性Contains 2 chromo domains.
  • 翻译后修饰Not phosphorylated.
    Ubiquitinated.
  • 细胞定位Nucleus. Unassociated with chromosomes during mitosis.

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) (ab6721) at 1/5000 dilution

    Predicted band size : 21 kDa
    Observed band size : 25 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 37 kDa (possible cross reactivity),47 kDa (possible cross reactivity).
  • CBX1 / HP1 beta was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to CBX1 / HP1 beta and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab10478.
    Secondary: Clean blot (HRP conjugate) at 1/1000 dilution.
    Band: 20ka: CBX1 / HP1 beta.
  • ab10478 at 1/200 staining human cervix cells by ICC/IF. The cells were fixed in 4% PFA for 15 minutes and permeabilized for 15 minutes in 0.5% Triton X100 in PBS, prior to incubation with the antibody fort 1 hour. A Cy2 ®  conjugated goat anti-rabbit antibody was used as the secondary.

    ab10478 staining CBX1 / HP1 in human testis, showing a distinct and strong staining pattern in ductus seminiferus cells. Paraffin embedded human skin tissue was incubated with ab10478 (1/400 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.

    ab10478 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org
