This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Dermatophagoides pteronyssinus GHITM / MICS1 ( Catalog#69005-A07E; P49278; Gln19-Asp146). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
