General Notes
This product (Catalog No. DPABH-22557) is a rabbit-derived polyclonal antibody raised against human KRT19, targeting the amino acid region 1–400 of the protein. This antibody exhibits cross-reactivity with Human KRT19 from mouse and rat. It has been affinity purified by Protein A. Keratin 19 (KRT19), or cytokeratin-19 (CK19), is a 40 kDa type I acidic intermediate filament protein encoded by the KRT19 gene on chromosome 17q21.2. It is a vital structural component of epithelial cells, including those in the gastrointestinal tract, breast, and bile ducts, often serving as a marker for carcinoma, particularly in thyroid cancer.
DPABH-22557 is suitable for use in ELISA (1:4,000–1:8,000), IHC (1:50–1:100), Western blot (WB) (1:1,000–1:4,000) applications.
DPABH-22557 is supplied as a liquid formulation in 0.01M PBS, pH 7.4, 50% Glycerol, 0.05% Proclin 300. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
