Rat Periostin (POSTN) ELISA Kit

Periostin (POSTN) is a secreted matricellular protein involved in extracellular matrix remodeling, tissue repair, and fibrotic responses across multiple organ systems. This Assay Genie immunoassay enables quantitative measurement of endogenous rat POSTN protein, supporting research into cardiovascular fibrosis, allergen-driven airway remodeling, periodontal tissue regeneration, and subepithelial thickening in asthma models.

The kit is supplied in a 96 assays configuration with pre-coated wells, calibration standards, biotinylated detection antibody, streptavidin conjugate, wash buffer, substrate solution, and stop reagent ready for immediate use. Investigators studying collagen deposition, myofibroblast differentiation, or epithelial-mesenchymal signaling can apply this assay to tissue homogenate preparations and supernatant fractions to characterize disease-associated changes in periostin secretion.

Research workflows using this kit commonly include comparisons between vehicle- and treatment-exposed groups, kinetic profiling after experimental injury, and correlation with histopathological fibrosis scoring. The microplate format integrates with standard laboratory plate readers and conventional wash equipment, fitting within immunoassay pipelines used in academic and pharmaceutical preclinical settings.
