Scientific Data Images for Human Claspin Antibody

Detection of Human Claspin antibody by Western Blot.

Detection of Human Claspin by Western Blot.

Western blot shows lysates of HCT-116 human colorectal carcinoma cell line, HEK293 human embryonic kidney cell line, and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Claspin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3310) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Claspin at approximately 199 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Claspin antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

Claspin in HeLa Human Cell Line.

Claspin was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Goat Anti-Human Claspin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3310) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Claspin

Claspin is a nuclear protein whose expression peaks during S and G2 phases of the cell cycle. Claspin is phosphorylated by ATR in response to DNA damage or replication stress. It functions in cell cycle checkpoint control by regulating the activation of Chk1 and BRCA1. Claspin contains three CKB motifs and two coiled coil regions. Over the range used for immunization, human and mouse Claspin share 72% amino acid sequence identity. DNA replication and DNA damage induce the phosphorylation of Claspin by Chk1-dependent mechanisms.
