Human Basic Salivary Proline Rich Protein 1 (PRB1) ELISA Kit

Salivary proline-rich proteins form a family of intrinsically disordered molecules secreted by the parotid and submandibular glands. PRB1, one of the basic members of this family, binds to tooth enamel surfaces and contributes to the acquired enamel pellicle, while also interacting with tannins and polyphenols in the oral cavity. Researchers studying oral biology, dental caries risk, taste perception, and salivary protein composition rely on quantitative measurement of PRB1 as a marker of glandular secretory activity.

This Assay Genie kit is configured as a colorimetric ELISA in a 96 assays format, intended for in vitro research use with human saliva and related oral fluid samples. Each kit includes the reagents required to generate a standard curve alongside unknown samples. The workflow uses absorbance plate-reader protocols and is compatible with standard laboratory instruments. The accompanying manual provides specific guidance on sample dilution, incubation times, and buffer preparation steps tailored to saliva matrices.

Saliva collection is non-invasive, allowing repeated sampling from the same donor for longitudinal studies of PRB1 expression under different physiological conditions, dietary interventions, or oral disease states. The kit ships as a complete package containing pre-coated wells, detection antibody, standards, and assay diluent. Storage and handling requirements are detailed in the product insert included with every order.
