Chk1 Antibody (MA1-91087) in WB

Western blot was performed using anti-Chk1 Mouse Monoclonal Antibody (Product # MA1-91087) a 54 kDa band was observed corresponding to Chk1 across the cell lines tested along with uncharacterized bands (*). Whole cell extracts of (30 µg lysate) of HeLa (Lane 1), SHSY5Y (Lane 2), HCT 116 (Lane 3), A549 (Lane 4), K562 (Lane 5) and HEK 293 (Lane 6) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blott... View More

Chk1 Antibody — FIGURE 6. Che-1 binds pericentrin and mediates its binding to Chk1. A, human lymphoblastoid AHH1 cells and CV1576 lymphoblastoid cells lacking PCNT expression were immunostained with the indicated antibodies. Bar diagrams show the percentages of cells with centrosomal colocalization of γ-tubulin and Che-1. B, Western blot analysis of isolated centrosome preparations or whole cell lysates from human lymphoblastoid AHH1 cells and PCNT-deficient cells. C, Western blot analysis of HCT116 cells untreated or treated with 1 µm Doxorubicin for 2 h. Total cellular extracts were immunoprecipitated (I.P.) with anti-Che-1 antibody and analyzed by Western blot using the indicated antibodies. D, total cellular extracts from HCT116 cells transiently transfected with GFP siRNA (siControl) or Che-1 siRNA (siChe-1) were immunoprecipitated with anti-Chk1 antibody and analyzed by Western blot using the indicated antibodies. The scale bar represents 5 µm. E, total cellular extracts from human lymphoblastoid AHH1 cells and CV1576 PCNT-deficient cells were immunoprecipitated (I.P.) with anti-Che-1 antibody and analyzed by Western blot using the indicated antibodies. F, total cellular extracts from HCT116 cells transiently transfected with GFP siRNA (siControl) or Chk1 siRNA (siChk1) were immunoprecipitated (I.P.) with anti-Che-1 antibody and analyzed by Western blot using the indicated antibodies. Immunoprecipitation negative control (Neg. control) was performed by using normal rabbit IgG. Scale bar represents 5 µm. Error bars represent S.D. after combining the results of {KD}

Target Information

CHEK1 (CHK1) is a serine/threonine protein kinase involved in preventing replication when DNA integrity is compromised. CHK1 is a key mediator in the DNA damage-induced checkpoint network. CHK1 is an evolutionarily conserved protein kinase that functions to ensure genomic integrity upon genotoxic stress. When the G2 or S checkpoint is abrogated by the inhibition of CHK1, p53-deficient cancer cells undergo mitotic catastrophe and eventually apoptosis, whereas normal cells are still arrested in the G1 phase. Thus, CHK1 inhibitors can preferentially potentiate the efficacy of DNA damaging agents in cancer cells, and Chk1 is an attractive therapeutic target for cancer treatment, especially since approximately 50% of all human cancers are p53-deficient.
