Note: The complete
sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is
translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 6xHis-SUMO-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.
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
Recombinant Dermatophagoides pteronyssinus Mite group 2 allergen Der p 2 (DERP2) is a partial-length protein expressed with N-terminal 6xHis-SUMO-tagged in the E.coli. It underwent validation via the LC-MS/MS analysis. Its purity was determined by SDS-PAGE and reached up to 90% and presented a molecular mass band around 30 kDa on the gel. This recombinant DERP2 protein may be used to synthesize antibodies against DERP2 or on the studies of DERP2-associated signal transduction.
DERP2 is a cause of an allergic reaction in human. Common symptoms of mite allergy are bronchial asthma, allergic rhinitis and conjunctivitis. This protein and and Dermatophagoides farinae (Der f) are the major source of allergens for patients allergic to house dust mites (HDMs).
