The ratio of hapten and bovine serum albumin in an antigen conjugate was de
termined by matrix-assisted laser desorption/ionization mass spectrometry.
A hybridoma secreting monoclonal antibody against ginsenoside Rb-1 was prod
uced by fusing splenocytes immunized with a ginsenoside Rb-1-bovine serum a
lbumin conjugate with HAT-sensitive mouse myeloma cell line, P3-X63-Ag8-653
. A very small cross-reaction appeared with ginsenoside Rc and ginsenoside
Rd. The full measuring range of the assay extends from 20 ngml(-1) to 400 n
gml(-1) of ginsenoside Rb-1.
