Anwendung

Quality Control TestingEvaluated by Flow Cytometry in HT1080 cells transfected with human Claudin-2.Flow Cytometry Analysis (FC): 1 μg of this antibody detected Claudin-2 in one million HT1080 cells transfected with human Claudin-2.Tested ApplicationsFlow Cytometry Analysis: A representative lot detected Claudin-2 in Flow Cytometry applications (Takigawa, M., et. al. (2017). J Pharmacol Exp Ther. 363(3):444-451).Inhibition Assay: A representative lot of this antibody inhibited TNFa-induced dysfunction of tight junction seals in the intestinal epithelium. (Takigawa, M., et. al. (2017). J Pharmacol Exp Ther. 363(3):444-451). Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Anti-Claudin-2, clone 1A2, Cat. No. MABT1454, is a rat monoclonal antibody that detects Claudin-2 and is tested for use in Flow Cytometry and Inhibition Assays.

Zielbeschreibung

Claudin-2 (UniProt: P57739; also known as SP82) is encoded by the CLDN2 (also known as PSEC0059, SP82, UNQ705/PRO1356) gene (Gene ID: 9075) in human. Claudin-2 is a multi-pass membrane protein with three cytoplasmic domains, two extracellular domains, and four transmembrane domains. It can exist as homopolymer or as a heteropolymer with other claudins mediated through the first extracellular domain (aa 29-81). These interactions are achieved largely through electrostatic interactions with Asp65 and with somewhat weaker interaction with electrons of the Tyr67. Claudin-2 is expression has been reported in liver, kidney, and small intestine. It is a component of epithelial tight junctions (TJ) that plays a key role in TJ-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. Its expression is shown to be enhanced in subjects with inflammatory bowel disease. Treatment with TNF-a is also reported to upregulate the expression of Claudin-2 via PI3-kinase signaling that reduces transepithelial electrical resistance (TEER). Clone 1A2 is shown to reduce TNF-a-induced reduction in TEER and restore TJ integrity. (Ref.: Takigawa, M., et al. (2017). J. Pharmacol. Exp. Ther. 363(3); 444-451).

Physikalische Form

Purified rat monoclonal antibody IgG2b in PBS without azide.

Lagerung und Haltbarkeit

Stable for 1 year at -10°C to -25°C from date of receipt. Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
