Myeloperoxidase/MPO Protein, Mouse (HEK293, His)

Myeloperoxidase (MPO) protein, integral to polymorphonuclear leukocytes' host defense system, catalyzes the production of hypohalous acids, notably hypochlorous acid, enhancing microbicidal activity.Beyond antimicrobial functions, MPO mediates the proteolytic cleavage of alpha-1-microglobulin, yielding t-alpha-1-microglobulin.This processed form inhibits low-density lipoprotein particle oxidation, contributing to vascular damage limitation.Myeloperoxidase/MPO Protein, Mouse (HEK293, His) is the recombinant mouse-derived Myeloperoxidase/MPO protein, expressed by HEK293 , with C-10*His labeled tag.

Myeloperoxidase (MPO) protein plays a vital role in the host defense system of polymorphonuclear leukocytes, contributing to microbicidal activity against a diverse range of organisms. Upon stimulation of polymorphonuclear leukocytes, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid under physiological conditions, along with other toxic intermediates that significantly enhance microbicidal activity in these cells. Beyond its antimicrobial functions, MPO is involved in mediating the proteolytic cleavage of alpha-1-microglobulin, generating t-alpha-1-microglobulin. This processed form exhibits potent inhibitory effects on the oxidation of low-density lipoprotein particles, thereby contributing to the limitation of vascular damage.

Measured by its ability to oxidize guaiacol in the presence of hydrogen peroxide., The specific activity is 16375.8504 pmol/min/µg, as measured under the described conditions.

Approximately 80-100 kDa due to the glycosylation.

• 
  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 7.4 or PBS, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween80.

<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.
