Source

Human Kallikrein 13 Protein, His Tag (KL3-H52H4) is expressed from human 293 cells (HEK293). It contains AA Gly 17 - Ile 262 (Accession # Q9UKR3).

Predicted N-terminus: Gly 17

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 28.9 kDa. The protein migrates as 30-38 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

Kallikrein 13 (KLK13), also known as KLK-L4, is a member of the human tissue kallikrein family of serine proteases located on chromosome 19q13.41. It encodes a secreted enzyme of about 277 amino acids that participates in proteolysis and extracellular matrix remodeling. KLK13 is expressed in several tissues, including prostate, breast, testis, and salivary gland. Emerging evidence links KLK13 to cancer biology, particularly in breast, ovarian, and prostate cancers, where it may serve as a biomarker for diagnosis or prognosis. Beyond oncology, KLK13 has been implicated in inflammatory processes and tissue homeostasis, highlighting its diverse physiological roles.
