Allows students to easily isolate chromosomal DNA from onion cells using the same basic tools and methods that scientists use in the lab. A good introduction to using pipettes. Kate Dollard - [Read DNA Isolation from Onion Cells]
Protocol describes methods for isolation of DNA from a strain of S. cerevisiae carrying a recombinant YAC. Because the linear YAC DNAs are sensitive to shearing forces, pipettes with wide-bore tips should be used to transfer DNAs. The method is suitable for preparing DNA that will be used for agarose gel electrophoresis, Southern blotting, subcloning, genomic library construction, PCR, or other methods that do not require intact high-molecular-weight DNA. - [Read Growth of S. cerevisiae and Preparation of DNA Protocol]
This protocol describes the determination of useful settings with the Sutter Puller P-97 to make injection pipettes for microinjection. - [Read Making Injection Pipettes Protocol]

his protocol provides methods for the preparation of protein samples and for loading them into pulled microinjection pipettes. Stock solutions of proteins are thawed, diluted (if desired), centrifuged at high speed to remove aggregates, and kept on ice until loading. Loading into micropipettes can be done using either a "front-loading" or a "backfilling" procedure. - [Read Preparation and Loading of Protein Samples for Microinjection Protocol]
Protocol describes a method for preparing siliconized pipettes. Such pipettes minimize the loss of embryos or embryonic tissues during transfer. - [Read Preparing Siliconized Pipettes Protocol]
