Protocol for 96-well confirmation Yeast PCR. Includes: Clonal purification; Generate a master plate (96-well format); Making a frozen backup stock; Confirmation PCR for one Row; ORF Specific Confirmation PCR --> "A-B" primers (upstream junction); Transfer template DNA to multiwell PCR plate; Prepare and dispense master mix for A-B PCR. - [Read 96-Well Confirmation Yeast PCR Protocol]
Investigators can utilize X chromosome inactivation (methylation) to determine the clonality status of a tumor or premalignant lesion in females. The technique is based on a methylation-sensitive restriction enzyme and analysis of a polymorphic locus on the X chromosome. Clonal cell populations will show "loss" of the non-methylated allele after restriction digest. The assay can be performed on DNA recovered from microdissected samples. Both frozen tissue and fixed-embedded tissue can be used. - [Read Clonality - X Chromosome Inactivation Assay Protocol]
Protocol describes the use of PCR to screen for bacteria that carry recombinant plasmids. The PCR can be carried out using the same primers as for amplification of the cloned insert. To determine the orientation of the insert, a third, insert-specific primer that is asymmetrically distanced from the clonal insertion site can be used. - [Read Colony PCR Protocol II]
