Product overview
Abcam’s knockout cell pellets give you access to native proteins, without the need to culture cells. Our knockout cell pellets are prepared from our single-gene knockout cell lines and provide an additional offering to our cell lysates.
Cells are snap-frozen to provide high quality pellets that are suitable for extraction with alternative lysis buffers or for preparation of lysates from subcellular fractions. Our knockout cell pellets are suitable for a variety of applications, including PCR, gene expression profiling and DNA library preparation. -

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 pellet (ab278871)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. -
