Anti-Chk1 (phospho S345) antibody 图像

  • ab47318 staining human breast carcinoma tissue by IHC-P (left hand panel). The right hand panel shows staining in the presence of phospho-peptide.
  • ab47318 (1/200) detecting Chk1 in HeLa cells in conjunction with a goat anti-rabbit secondary antibody conjugated to Cy3® (red). Cells were also counterstained with DAPI in order to highlight the nucleus (blue), treated with Bleomycin and incubated with an antibody against Histone H2AX in order to create and expose DNA double strand breaks (green). Please refer to abreviews for further details.
