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).
