Scientific Data Images for Human Serpin A1/ alpha 1‑Antitrypsin Antibody

Western Blot Shows Serpin A1/ alpha 1‑Antitrypsin Specificity Using Knockout Cell Line.

Western blot shows lysates of HepG2 human hepatocellular carcinoma parental cell line and Serpin A1/ alpha 1‑Antitrypsin knockout HepG2 cell line (KO). Nitrocellulose membrane was probed with Mouse Anti-Human Serpin A1/ alpha 1‑Antitrypsin Monoclonal Antibody (Catalog # MAB1268) followed by HRP-conjugated secondary antibody. A specific band was detected for Serpin A1/ alpha 1‑Antitrypsin at approximately 46.7 kDa (as indicated) in the parental HepG2 cell line, but is not detectable in knockout HepG2 cell line. Primary antibody dilution used: 1 ug/ml. The Ponceau stained transfer of the blot is shown. This experiment was conducted under reducing conditions.

Detection of Serpin A1/ alpha 1‑Antitrypsin by Immunoprecipitation.

HepG2 human hepatocellular carcinoma cell line lysates were prepared and immunoprecipitation was performed using 2.0 µg of Mouse Anti-Human Serpin A1/ alpha 1‑Antitrypsin Monoclonal Antibody (Catalog # MAB1268) pre-coupled to Dynabeads Protein G. Immunoprecipitated Serpin A1/ alpha 1‑Antitrypsin was detected in Western Blot with a rabbit anti-Serpin A1 used at 1/5000. The Ponceau stained transfer of the blot is shown. SM=4% starting material; UB=4% unbound fraction; IP=immunoprecipitate; HC=antibody heavy chain. Image, protocol and testing courtesy of YCharOS Inc. (ycharos.com).

Detection of Human Serpin A1/ alpha 1‑Antitrypsin by Western Blot.

Western blot shows human plasma and lysates of human lung tissue and human kidney tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Serpin A1/a1-Antitrypsin Monoclonal Antibody (Catalog # MAB1268) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). Specific bands were detected for Serpin A1/a1-Antitrypsin at approximately 50-60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Serpin A1/ alpha 1‑Antitrypsin in HepG2 Human Cell Line.

Serpin A1/a1-Antitrypsin was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Mouse Anti-Human Serpin A1/ a1-Antitrypsin Monoclonal Antibody (Catalog # MAB1268) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; NL007) and counter-stained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Serpin A1/ alpha 1‑Antitrypsin by Simple WesternTM.

Simple Western lane view shows lysates of human plasma, loaded at 0.2 mg/mL. A specific band was detected for Serpin A1/ alpha 1‑Antitrypsin at approximately 65 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Serpin A1/ alpha 1‑Antitrypsin Monoclonal Antibody (Catalog # MAB1268). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Detection of Serpin A1/ alpha 1‑Antitrypsin in Human Prostate.

Serpin A1/ alpha 1‑Antitrypsin was detected in immersion fixed paraffin-embedded sections of Human Prostate using Mouse Anti-Human Serpin A1/ alpha 1‑Antitrypsin Monoclonal Antibody (Catalog # MAB1268) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in epithelial cells.

Background: Serpin A1/alpha 1-Antitrypsin

Serpin A1 is the archetypal member of the Serpin superfamily of the serine protease inhibitors (1). As one of the most abundant proteinase inhibitors in the circulation, it is synthesized in the liver and secreted into the bloodstream with the major function to protect tissues against neutrophil elastase. A severe Serpin A1 deficiency leads to several clinical complications such as pulmonary emphysema, juvenile hepatitis, cirrhosis, and hepatocellular carcinoma (2). The deficiency is caused by point mutations in naturally occurring Serpin A1 variants (over 70 are known). For example, the Z variant (Glu342 to Lys) forms intracellular inclusion bodies, is not secreted, and leads to a severe Serpin A1 deficiency (3).
