HPX Protein, Cynomolgus, Recombinant (His)

Hemopexin (HPX) serves as scavenger and transporter of toxic plasma heme to the liver. HPX is formed by two four-bladed beta-propeller domains, resembling two thick disks that lock together at a 90 degrees angle. The heme is bound between the two beta-propeller domains in a pocket formed by the interdomain linker peptide.HPX, acting not only as a heme carrier but also displaying transient heme-based ligand binding and (pseudo-)enzymatic properties, could be considered a 'chronosteric' heme-protein.

Description

Species	Cynomolgus
Expression System	HEK293
Tag	C-His
Accession Number	A0A2K5WVL1
Synonyms	Hemopexin, Hpx, Hpxn
Construction	Recombinant Cynomolgus HPX Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asn24-Tyr462.[Accession \|A0A2K5WVL1]
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	The protein has a predicted MW of 50.30 kDa. Due to glycosylation, the protein migrates to 60-80 kDa based on Tris-Bis PAGE result.

Endotoxin	Less than 1EU per μg by the LAL method.
Formulation	Lyophilized from 0.22μm filtered solution in 20mM MES, 150mM NaCl (pH 6.0). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 20mM MES, 150mM NaCl (pH 6.0).
Stability & Storage	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
