Human Cytokeratin 19 Antibody

Cytokeratin 19 in Human Breast Cancer Tissue Using Dual RNAscope^®ISH and IHC. Cytokeratin 19 mRNA (red) and protein (green) was detected in formalin-fixed paraffin-embedded tissue sections of human breast cancer tissue probed with ACD RNAScope^®Probe (Catalog # 310221) followed by immunohistochemistry using R&D Systems Mouse Anti-Human Cytokeratin 19 Monoclonal Antibody (Catalog # MAB35061) at 15ug/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte HRP Polymer Antibody (R&D Systems, Catalog # VC001). Tissue was stained using ACD RNAscope^®2.5 HD Duplex Detection Reagents (Catalog # 322500).

Detection of Human Cytokeratin 19 by Western Blot. Western blot shows lysates of HT-29 human colon adenocarcinoma cell line, ZR-75 human breast cancer cell line, DU145 human prostate carcinoma cell line, MCF-7 human breast cancer cell line, and A431 human epithelial carcinoma cell line. PVDF membrane was probed with 0.25 µg/mL of Mouse Anti-Human Cytokeratin 19 Monoclonal Antibody (Catalog # MAB35061) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Cytokeratin 19 at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Cytokeratin 19 in MCF‑7 Human Cell Line. Cytokeratin 19 was detected in immersion fixed MCF-7 human breast cancer cell line using Mouse Anti-Human Cytokeratin 19 Monoclonal Antibody (Catalog # MAB35061) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Cytokeratin 19 by Simple Western^TM. Simple Western lane view shows lysates of MCF‑7 human breast cancer cell line and HT‑29 human colon adenocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Cytokeratin 19 at approximately 50 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Cytokeratin 19 Monoclonal Antibody (Catalog # MAB35061). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
