Monoclonal Mouse Ascites E B IH IF
Chromatin assembly factor-1 (CAF-1) is a multisubunit protein complex that comprises three polypeptide subunits known as p150, p60, and p48. CAF-1 is a nucleosome assembly factor that deposits newly synthesized and acetylated histones H3/H4 into nascent chromatin during DNA replication. Heterochromatin is characterized as densely coiled chromatin that generally replicates late during S phase, has a low gene density, and contains large blocks of repetitive DNA that is relatively inaccessible to DNA-modifying reagents. In late S phase, p150 directly associates with heterochromatin associated proteins 1 (HP1alpha, HP1beta and HP1gamma). As cells prepare for mitosis, CAF-1 p150 and some HP1 progressively dissociate from heterochromatin, coinciding with the phosphorylation of histone H3. The HP1 proteins reassociate with chromatin at the end of mitosis, as histone H3 is dephosphorylated.
Catalog #H2034-52
ApplicationsSuitable for use in Western Blot, Immunofluorescence, Immunohistochemistry and ELISA. Other applications not tested.
Recommended DilutionsWestern Blot: 1:500 detected HP1gamma on 10ug of A431 lysates. A431 lysate was resolved by electrophoresis, transferred to PVDF and probed with diluted H2034-52. Proteins were visualized using an IgG (HRP) Gt xMo* and a chemiluminescence detection system.
Immunofluorescence: 1:500-1:5000
Immunohistochemistry: 1:500-1:5000
ELISA: 1:500-1:5000
Optimal dilution determined by the researcher.
