Human Basic Salivary Proline Rich Protein 3 (PRB3) ELISA Kit

Quantitative measurement of human basic salivary proline-rich protein 3 in research samples is achieved through this ELISA kit from Assay Genie. PRB3 belongs to a family of secretory proteins produced by parotid and submandibular salivary glands, where the proline-rich sequences contribute to lubrication of the oral cavity, binding of dietary polyphenols, and formation of the acquired enamel pellicle that protects tooth surfaces from demineralization. Altered PRB3 expression has been investigated in studies of dental caries susceptibility, Sjögren's syndrome, xerostomia, and oral squamous cell carcinoma, making accurate quantification relevant across oral biology, dental research, and biomarker discovery efforts.

The assay accepts multiple input matrices used in salivary and systemic studies, including whole tissue homogenates, prepared cell lysates, and harvested cell culture supernatants. Reagents should be refrigerated on arrival and stored according to the enclosed insert to preserve the coated microplate and detection antibody. Each kit supplies a pre-coated microplate, calibration standards, assay buffers, and enzyme conjugate reagents sufficient to perform the indicated number of determinations per plate.
