Yeast colonies are suspended in complete PCR buffer and transferred to a thermal cycler for 35 cycles of PCR. The products of the amplification reaction are analyzed by gel electrophoresis. - [Read Analyzing Yeast Colonies by PCR Protocol]

Protocol provides methods for cryofreezing and subsequent thawing of mammalian cells. Pre-confluent cells are trypsinized, pelleted, resuspended in freezing medium, and gradually frozen. When needed, frozen cells are thawed quickly under running tap water and transferred to growth medium. - [Read Cryopreservation of Mammalian Culture Cells: Preparation and Recovery of Samples Protocol]

The transfer of proteins from a Tris/glycine SDS-polyacrylamide gel to a membrane using a semi-dry method is achieved by placing the gel next to a piece of nitrocellulose filter.  This sandwich is placed directly between two plate electrodes, and the proteins are then transferred from the gel onto the filter. - [Read Immunoblotting: Semi-Dry Electrophoretic Transfer of Proteins from Gels to Membranes Protocol]

Bacterial colonies growing on agar plates are transferred en masse to nitrocellulose filters. The spatial arrangement of colonies on the plates is preserved on the filters. After transfer, the filters are processed for hybridization to an appropriate radiolabeled probe while the original (master) plate is incubated for a few hours to allow the bacterial colonies to regrow in their original positions. - [Read Screening Bacterial Colonies by Hybridization: Intermediate Numbers Protocol]

A cDNA library constructed in a plasmid expression vector of the pUC, pUR, or pEX series is plated on agar medium and then replicated onto filters, which are transferred to plates containing IPTG. After 2-4 hours of induction, the colonies are lysed with chloroform and then screened with appropriate antibodies. - [Read Screening Expression Libraries Constructed in Plasmid Vectors Protocol]

Protocol for southern blotting: simultaneous transfer of DNA from a single agarose gel to two membranes. DNA can be simultaneously transferred from opposite sides of a single agarose gel to two membranes.  Bidirectional transfer occurs rapidly at first, but soon slows down as the gel becomes dehydrated.  Because the efficiency of transfer is low, the method works best when the target sequences are present in high concentration - [Read Southern Blotting: Simultaneous Transfer of DNA from a Single Agarose Gel to Two Membranes Protocol]

The liver of a rat is cannulated and perfused in situ with buffer, following which it is excised and perfused in a closed system with a collagenase solution. After a period of time the liver begins to break up, at which point it is transferred to a measuring cylinder and culture medium is added. It is then gently agitated to cause the release of cells which are subsequently filtered and allowed to settle out. The parenchymal and non-parenchymal cells form two distinct layers which can be separat - [Read The Isolation and Culture of Rat Hepatic Cells Protocol]
