Zygotes can be identified by their unique morphology. They can be easily separated away from nonmated cells using a micromanipulator. This method provides an alternative to the selection of diploid cells on a medium that prevents the growth of haploid parent cells. - [Read Picking Zygotes Protocol]
RNA-RNA in situ hybridization using DIG-labeled probes: the effect of high molecular weight polyvinyl alcohol on the alkaline phosphatase indoxyl-nitroblue tetrazolium reaction. RNA-RNA in situ hybridization protocol using alkaline phosphatase-conjugated digoxigenin-(DIG-) labeled probes is presented. The addition of polyvinyl alcohol (PVA) of high molecular weight (40 – 100 kD) to the BCIP-NBT detection system enhances the alkaline phosphatase reaction and prevents... - [Read RNA-RNA In Situ Hybridization Using DIG-Labeled Probes Protocol]
