ターゲット情報
- 機能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.
- 組織特異性Expressed in all adult and embryonic tissues.
- 配列類似性Contains 2 chromo domains.
- 翻訳後修飾Not phosphorylated.
Ubiquitinated. - 細胞内局在Nucleus. Unassociated with chromosomes during mitosis.

Western blot - Anti-CBX1 / HP1 beta antibody (ab10478)
Predicted band size : 21 kDaLanes:
Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: CBX1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: MCF7 whole cell lysate (20 µg)
Lane 4: A431 whole cell lysate (20 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab10478 observed at 26 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab10478 was shown to recognize CBX1 when CBX1 knockout samples were used, along with additional cross-reactive bands. Wild-type and CBX1 knockout samples were subjected to SDS-PAGE. Ab10478 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Immunoprecipitation - Anti-CBX1 / HP1 beta antibody (ab10478)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.

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.
