The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
1/2000 - 1/10000. Detects a band of approximately 25, 65, 130, 240 kDa (predicted molecular weight: 61 kDa).
Use at 2-5 µg/mg of lysate.
FunctionComplex that is thought to mediate chromatin assembly in DNA replication and DNA repair. Assembles histone octamers onto replicating DNA in vitro. CAF-1 performs the first step of the nucleosome assembly process, bringing newly synthesized histones H3 and H4 to replicating DNA; histones H2A/H2B can bind to this chromatin precursor subsequent to DNA replication to complete the histone octamer. The CCR4-NOT complex functions as general transcription regulation complex.
Sequence similaritiesBelongs to the WD repeat HIR1 family. Contains 7 WD repeats.
Developmental stageActive complex is found in G1, S and G2 phases.
Post-translational modificationsDifferentially phosphorylated during cell cycle. During mitosis the p60 subunit of inactive CAF-1 is hyperphosphorylated and displaced into the cytosol. Progressivly dephosphorylated from G1 to S and G2 phase. Phosphorylated p60 is recruited to chromatin undergoing DNA repair after UV irradiation in G1, S or G2 phases.
Cellular localizationNucleus. Cytoplasm. DNA replication foci. Cytoplasmic in M phase.

ab72520 staining p60 CAF1 in human PC3 prostate cancer cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 pH 7.4 for 5 minutes at room temperature and blocked with 5% BSA for 20 minutes at room temperature. Samples were incubated with primary antibody (1/100 in PBS) for 1 hour. A CF568-conjugated donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.
