GPNMB/Osteoactivin Protein, Human (HEK293, His)

GPNMB, also known as osteoactivin, is a protein thought to have a potential role as a melanin-producing enzyme. Melanogenic enzymes are involved in the production of melanin, the pigment that determines skin, hair and eye color. GPNMB/Osteoactivin Protein, Human (HEK293, His) is the recombinant human-derived GPNMB/Osteoactivin protein, expressed by HEK293 , with C-6*His labeled tag. The total length of GPNMB/Osteoactivin Protein, Human (HEK293, His) is 465 a.a., with molecular weight of 80-120 kDa.

GPNMB, also referred to as Osteoactivin, is a protein that has been proposed to have a potential role as a melanogenic enzyme. Melanogenic enzymes are involved in the production of melanin, the pigment responsible for skin, hair, and eye color. While the exact mechanism of action of GPNMB in melanin synthesis is not fully understood, studies have suggested its involvement in this process. Further research is needed to elucidate the specific functions and regulatory mechanisms of GPNMB in melanogenesis and to determine its significance in melanin production.

• 
  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2 or 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
