Category: Epigenetics and Methylation Protocols

The pattern and extent of DNA methylation can significantly affect the success of restriction digestions or bacterial transformations. Prokaryotic DNA may be methylated by host restriction/modification systems, while eukaryotic DNA often is methylated i - [Read A practical guide to DNA methylation Promega PDF]

Category: Cell Culture Protocols: Cell Storing and Cell Freezing Protocols

Cryogenic preservation (storage below -100°C) of cell cultures is widely used to maintain backups or reserves of cells without the associated effort and expense of feeding and caring for them. The success of the freezing process depends on four critical areas: Proper handling and gentle harvesting of the cultures; Correct use of the cryoprotective agent; A controlled rate of freezing; Storage under proper cryogenic conditions. - [Read Cryogenic Preservation and Storage of Animal Cells Protocol]

This protocol decribes derivation of TS cell lines from 3.5-days post coitum (dpc) mouse blastocysts. The procedure is similar to the derivation of embryonic stem (ES) cell lines. However, the success rate is considerably higher, and less expertise is required to recognize pluripotent TS cell colonies. - [Read Derivation of Trophoblast Stem (TS) Cell Lines from Blastocysts Protocol]

Category: DNA Microarray Protocols

The "7 keys to successful microarray analysis" has been designed to guide researchers step-by-step through the design, implementation, analysis, and publication of a microarray experiment. - [Read Microarray Success]

Category: Viral Manipulation Protocols: Phage Protocols

Protocol describes methods to superinfect bacteria carrying a recombinant phagemid with a high-titer stock of an appropriate helper virus and to assay the yield of filamentous virus particles that carry single-stranded copies of the phagemid DNA. The key to success in using phagemids is to prepare a stock of helper virus whose titer is accurately known. - [Read Producing Single-stranded DNA with Phagemid Vectors Protocol]

Category: Primary Cell Isolation and Culture Protocols: Mammalian Cell Culture Protocols

Cryopreserved PBMCs are a common specimen source for studies of immunological responses to vaccines, immunotherapies, etc. The health and viability of cells recovered post-cryopreservation are of course critical to the success and accuracy of immunological assays performed on them. This protocol standardizes PBMC isolation and cryopreservation techniques, specifically for the assessment of thawed cells by cytokine flow cytometry. - [Read Protocol for Isolation, Cryopreservation, and Thawing of PBMCs]
