Source

Human Kallikrein 8 Protein, His Tag (KL8-H52H3) is expressed from human 293 cells (HEK293). It contains AA Gln 29 - Gly 260 (Accession # O60259).

Predicted N-terminus: Gln 29

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 26.8 kDa. The protein migrates as 32-35 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.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.5 with trehalose as protectant.
