Human Phospho-Chk2 (T68) Antibody

Detection of Human Phospho-Chk2 (T68) by Western Blot.

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 1 µM camptothecin (CPT) for 1 hour. PVDF membrane was probed with 0.5 µg/mL Rabbit Anti-Human Phospho-Chk2 (T68) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1626) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band for Phospho-Chk2 (T68) was detected at approximately 64 kDa (as indicated). The phospho-specificity of this antibody was supported by decreased labeling following treatment with 600 U lambda-phosphatase (lambda-PPase) for 60 minutes. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Phospho-Chk2 (T68) in HepG2 Human Cell Line.

Phopsho-Chk2 (T68) was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line treated with 1 µM camptothecin using Rabbit Anti-Human Phospho-Chk2 (T68) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1626) at 1 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to nuclei in treated cells. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
