Recovery of purified vitellogenin added to dilution buffer and measured via competitive polyclonal ELISA. Multiple dilutions of purified vitellogenin were prepared in PBS/1% BSA and incubated with antivitellogenin rabbit polyclonal antiserum prior to exposure to microtiter plates coated with the identical purified vitellogenin. Recovery is based on purified vitellogenin concentration of 600 μg/mL.
