Isotype

Mouse IgG1 kappa

Specificity

The antibody BA-17 reacts with cytokeratin 19 (40 kDa intracellular antigen) in human tissue. Cytokeratin 19 is not expressed in hepatocytes; it is often co-expressed with cytokeratin 7.

Application

IP, WB, FC (QC tested), IHC(P), ICC

Application details

Western blotting: Recommended dilution: 1-2 μg/ml.

Reactivity

Human

Immunogen

Mammary organoids.

Concentration

1 mg/ml

Preparation

Purified antibody is conjugated with biotin LC-NHS ester under optimum conditions and unconjugated antibody and free biotin are removed by size-exclusion chromatography.

Formulation

Phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Storage and handling

Store at 2-8°C. Do not freeze.

Antigen description

Cytokeratins are a subfamily of intermediate filaments and characterized by remarkable biochemical diversity. They are represented in epithelial tissues by at least 20 different polypeptides, molecular weight between 40 kDa and 68 kDa. The individual cytokeratin polypeptides are designated 1 to 20 and divided into the type I (acidic cytokeratins 9-20) and type II (basic to neutral cytokeratins 1-8) families.

Entrez Gene ID 3880

UniProt ID P08727

Western blotting analysis of human cytokeratin 19 using mouse monoclonal antibody BA-17 on lysates of HT-29 cell line and MOLT-4 cell line (cytokeratin non-expressing cell line; negative control) under non-reducing and reducing conditions. Nitrocellulose membrane was probed with 2 µg/ml of biotinylated mouse anti-cytokeratin 19 monoclonal antibody followed by IRDye800-conjugated streptavidin. Cytokeratin 19 was detected at approximately 41 kDa.
