Passage number
Knockout validation
Sanger Sequencing, Western Blot (WB)Reconstitution notes
To use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.*Usage of SDS sample buffer is not recommended with these lyophilized lysates.
Notes
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.
Access thousands of knockout cell lysates, generated from commonly used cancer cell lines.

Function
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. -
Tissue specificity
Expressed in all adult and embryonic tissues. -
Sequence similarities
Contains 2 chromo domains. -
Post-translational
modificationsNot phosphorylated.
Ubiquitinated. -
Cellular localization
Nucleus. Unassociated with chromosomes during mitosis. - Information by UniProt

Western blot - Human CBX1 (HP1 beta) knockout HEK293T cell lysate (ab257383)Lane 1: Wild-type HEK-293T cell lysate (20µg)
Lane 2: CBX1 knockout HEK-293T cell lysate (20µg)
Lanes 1- 2: Merged signal (red and green). Green - ab10478 observed at 26 kDa. Red - loading control ab7291 observed at 50 kDa.
ab10478 Anti-CBX1 / HP1 beta antibody was shown to specifically react with CBX1 / HP1 beta in wild-type HEK-293T cells in western blot. Loss of signal was observed when knockout cell line ab266356 (knockout cell lysate ab257383) was used. Wild-type and CBX1 / HP1 beta knockout samples were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab10478 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging. -
