| Abstract: | Wogonin 7-O-β-D-glucuronide (Wgn) is a bioactive flavone present in the dried root of Scutellaria baicalensis Georgi. To generate a monoclonal antibody (MAb) against Wgn, BALB/c mice injected with Wgn–bovine serum albumin yielded splenocytes that we fused with SP2/0 myeloma cells using the polyethylene glycol method. We obtained a hybridoma designated 315A that produced a MAb reactive to Wgn. The anti-Wgn MAb 315A was applied to an indirect competitive enzyme-linked immunosorbent assay (icELISA) to quantify Wgn. Subsequent validation revealed that icELISA using the 315A anti-Wgn MAb is an accurate and reliable method for the quantification of Wgn in S. baicalensis. |
