Optimized DNA sequence encoding mature chain of human Olfactomedin-4 (OLFM4) (Asp 21 - GLN510) including an C terminal His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant human Olfactomedin-4 is a protein consisting of 495 amino acid residue subunits,due to glycosylation migrates as an approximately 65kDa band protein on reduced SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant  human Olfactomedin-4 is lyophilized  from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

Recombinant Olfactomedin-4 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

OLFM4 (also called hGC-1 and GW112) is a member of the olfactomedin family, which is characterized by the presence of an olfactomedin domain in the C terminus (5). Olfactomedin-related proteins have distinct tissue expression patterns and diverse cellular functions. OLFM4 is expressed in epithelial cells of the prostate, small intestine, colon, and cells in the bone marrow. It is also expressed in several cancers and up- regulated in epithelial cells during inflammation
