Scientific Data Images for Human/Mouse IkB-alpha Antibody

Detection of Human/Mouse IkB-a antibody by Western Blot.

Detection of Human/Mouse IkB-alpha by Western Blot.

Western blot shows lysates of NIH-3T3 mouse embryonic fibroblast cell line, DA3 mouse myeloma cell line, LNCaP human prostate cancer cell line, and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.1 µg/mL of Sheep Anti-Human/Mouse IkB-a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4299) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for IkB-a at approximately 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
IkB-a antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

IkB‑ alpha in HeLa Human Cell Line.

IkB-a was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human/Mouse IkB-a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4299) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: IkB-alpha

NF kappaB inhibitor alpha (IkB-alpha) inhibits the NF kappaB complex by binding and sequestering it in the cytoplasm. Upon stimulation, IkB-alpha is phosphorylated on serine residues marking it for degradation by the ubiquitin pathway. Following IkB-alpha degradation, the NF kappaB complex is able to translocate to the nucleus and activate transcription.
