Purification and characterization of 26S proteasomes from human and mouse spermatozoa.

abstract：:We have developed a competitive reverse transcription-polymerase chain reaction (RT-PCR) sensitive enough to detect and quantify as little as 2-fold differences in gene expression in individual oocytes and embryos throughout human preimplantation development. This RT-PCR assay can be tailored for the examination of an...
