Function

Salivary protein that stabilizes saliva supersaturated with calcium salts by inhibiting the precipitation of calcium phosphate salts. It also modulates hydroxyapatite crystal formation on the tooth surface.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Secreted by parotid and submandibular glands

Product Specifications

Recombinant Human Statherin (STATH) is a recombinant protein from Homo sapiens (Human), expressed in E.coli, covering amino acids 20-62aa, with N-terminal 10xHis-SUMO-tagged tag, molecular weight 23.7kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.
