Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 10xHis-tagged and C-terminal Myc-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
The region for expressing recombinant Human LPO contains amino acids 81-712. This LPO protein is theoretically predicted to have a molecular weight of 76.6 kDa. Expression of this LPO protein is conducted in mammalian cell. The N-terminal 10xHis tag and C-terminal Myc tag was fused into the coding gene segment of LPO, making it easier to detect and purify the LPO recombinant protein in the later stages of expression and purification.
The human lactoperoxidase (LPO) is an enzyme belonging to the peroxidase family and is primarily found in secretory fluids such as milk, saliva, and tears. LPO plays a crucial role in innate immune defense mechanisms. It contributes to the antimicrobial activity of these fluids by catalyzing the oxidation of thiocyanate and iodide ions, producing reactive intermediates that possess antimicrobial properties. Additionally, LPO is involved in the generation of reactive oxygen species, contributing to the elimination of bacteria and other pathogens. Research on lactoperoxidase focuses on its role in host defense, its potential applications in food preservation, and its relevance to human health.
