General Notes
This product (Catalog No. CABT-BL1075) is a rabbit-derived polyclonal antibody raised against human CLDN9, targeting the amino acid region 29–81 of the protein. It has been affinity purified by Protein A. CLDN9 is a protein-coding gene in humans that encodes claudin-9, an integral membrane protein belonging to the claudin family, which forms the structural components of tight junctions in epithelial and endothelial cells. These tight junctions act as barriers to regulate paracellular permeability, preventing the free passage of solutes and water while maintaining cell polarity and facilitating signal transduction. Claudin-9 specifically contributes to calcium-independent cell adhesion and is essential for the obliteration of intercellular spaces in tight junctions.
CABT-BL1075 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.
CABT-BL1075 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.
