J. Moos et al., RAPID, NONRADIOACTIVE, AND QUANTITATIVE METHOD TO ANALYZE ZONA-PELLUCIDA MODIFICATIONS IN SINGLE-MOUSE EGGS, Molecular reproduction and development, 38(1), 1994, pp. 91-93
A rapid, nonradioactive method to monitor the ZP2 to ZP2(f) conversion
in the zona pellucida of single mouse eggs has been developed. This a
ssay is based on the chemiluminescent detection of biotinylated ZP2 an
d ZP2(f) following electrophoresis under reducing conditions and elect
rophoretic transfer to Immobilon P. This method is about 10 times fast
er and detects similar ex tents of ZP2 to ZP2(f) conversion following
A23187-induced egg activation, when compared to the commonly used radi
oiodination procedures. (C) 1994 Wiley-Liss, Inc.
