>90%

Supplied as lyophilized form in PBS, pH7.4, containing 5% trehalose, 0.01% sarcosyl.

Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months.
Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

Manufactured in an ISO 9001:2008 and ISO 13485:2003 Certified Laboratory.

Manufactured in a lab with traceable raw materials. Bulk orders can typically be prepared to the customera??s specifications, please inquire.

Small volumes of HPD recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

HPPD_HUMAN

The protein encoded by this gene is an enzyme in the catabolic pathway of tyrosine. The encoded protein catalyzes the conversion of 4-hydroxyphenylpyruvate to homogentisate. Defects in this gene are a cause of tyrosinemia type 3 (TYRO3) and hawkinsinuria (HAWK). Two transcript variants encoding different isoforms have been found for this gene.

HPD: Key enzyme in the degradation of tyrosine. Defects in HPD are the cause of tyrosinemia type 3 (TYRO3). TYRO3 is an inborn error of metabolism characterized by elevations of tyrosine in the blood and urine, seizures and mild mental retardation. Defects in HPD are a cause of hawkinsinuria (HAWK). HAWK is an inborn error of tyrosine metabolism characterized by failure to thrive, persistent metabolic acidosis, fine and sparse hair, and excretion of the unusual cyclic amino acid metabolite, hawkinsin, in the urine. Belongs to the 4HPPD family. 2 isoforms of the human protein are produced by alternative splicing.
