Polyvalent Dengue Antigen-I for ELISA Recombinant

Lyophilized powder at room temperature

Description: Polyvalent dengue antigens are 18kDa proteins containing subtype 1, 2, 3 and 4. They are a new group of antigens specifically designed for ELISA assay. Except common epitopes shared by each subtype, this group of peptides also contains subtype specific epitopes, sometimes OD value peaks at one individual subtype. Dengue infection may miss without including all four subtype antigens. All the recombinant peptides are fused with a 6xHis Tag. Polyvalent dengue is purified by proprietary chromatographic technique. The product is supplied in 4 different vials, 1 for each subtype, when ordering 100ug, you will receive 4x25ug/vial (1 vial/subtype).
Physical Appearance and Stability: Polyvalent dengue Recombinant although stable at 4C for 1 week, should be stored below -18C. Please prevent freeze thaw cycles.
Formulation and Purity: 50mM sodium chloride-phosphorous buffer, pH-7.4. Protein is >95% pure as determined by 10% PAGE (coomassie staining).
