Protocol describes a method to collect early embryos from 6-week-old mice. Subsequently, the isolated embryos can be injected with double-stranded RNA to induce knockdown of a gene of interest. - [Read Collection of Early Mouse Embryos for RNAi Protocol]
Protocol describes a method to collect oocytes from 6-week-old mice. Subsequently, the isolated oocytes can be injected with double-stranded RNA to induce knockdown of a gene of interest. - [Read Collection of Mouse Oocytes for RNAi Protocol]
This protocol has been established to maintain the efficient use of the AutoMACS cell sorter during periods of heavy use (e.g., three preparations of splenocytes from 16 spleens per week). Includes: Running the SAFE Clean Program; Clearing Debris. - [Read Maintenance of the AutoMACS Cell Sorter Protocol]
Paraformaldehyde Fixation of Cells protocol. This fixation method is good for cells labeled by fluorochrome-conjugated antibodies to membrane antigens. It will stabilize the light scatter and labeling for up to a week in most instances, allowing you to be more flexible in scheduling cytometer time. Furthermore, it inactivates most biohazardous agents, so it is important from a safety standpoint as well. Iowa University. - [Read Paraformaldehyde Fixation of Cells]
In general, peptide solutions are stable for up to a week at 4°C. However, if the peptide sequence has inherent instability (Peptide Stability), it might be better to freeze the solution when not in use. Peptide solutions at pH>8 should also be frozen when not in use. Sigma Aldrich. - [Read Peptide Handling and Storage]
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
