Histone H4 [Methyl Lys20] Antibody - BSA Free

Western Blot: Histone H4 [Methyl Lys20] Antibody [NBP2-59258]

Western Blot: Histone H4 [Methyl Lys20] Antibody [NBP2-59258] - Western blot was performed on whole cell extracts (25 ug, lane 1) from HeLa cells, and on 1 ug of recombinant histone H2A, H2B, H3 and H4 (lane 2, 3, 4 and 5, respectively) using the antibody against H4K20me1. The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left, the position of the protein is indicated on the right.

Immunocytochemistry/ Immunofluorescence: Histone H4 [Methyl Lys20] Antibody [NBP2-59258]

Immunocytochemistry/Immunofluorescence: Histone H4 [Methyl Lys20] Antibody [NBP2-59258] - HeLa cells were stained with the antibody against H4K20me1 and with DAPI. Cells were fixed with 4% formaldehyde for 10' and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labeled with the H4K20me1 antibody (left) diluted 1:500 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa Fluor 488. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right.

Chromatin Immunoprecipitation: Histone H4 [Methyl Lys20] Antibody [NBP2-59258] - ChIP assays were performed using human HeLa cells, the antibody against H4K20me1 and optimized PCR primer sets for qPCR. ChIP was performed with a ChIP-seq kit on sheared chromatin from 1 million cells. A titration of the antibody consisting of 1, 2, 5, and 10 ug per ChIP experiment was analysed. IgG (2 ug/IP) was used as negative IP control. QPCR was performed with primers for the coding region of the active GAPDH and ACTB genes, used as positive controls, and for the GAPDH promoter and a region located 1 kb upstream of the GAPDH promoter, used as negative controls. Figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
