POSTN Protein (C-His, Human)

Product Specifications

Abbreviation

POSTN

Synonyms

OSF-2, OSF2, PDLPOSTN, periostin, PN

Host

HEK 293

Tag

C-His

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method

Purity

≥ 95 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.

Bioactivity

Measured by its ability to induce adhesion of ATDC5 mouse chondrogenic cells.When cells are added to POSTN-His coated plates (20μg/mL, 100μL/well), approximately >45% will adhere specifically after 30 minutes at 37°C.

Function

Met1-Gln781

Molecular Weight

The recombinant human POSTN consists of 771 amino acids and has a predicted molecular mass of 86.4 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 66-80 kDa due to glycosylation.
