This protocol describes the isolation of fibroblasts from mouse embryos. Mouse embryonic fibroblast (MEF) cells are used as a feeder layer for the culture of mouse embryonic stem (ES) cells to help maintain them as pluripotent stem cells. The inhibition of ES-cell differentiation provided by the MEF feeders appears to be due to their production of leukemia inhibitory factor (LIF). - [Read Isolation and Freezing of Primary Mouse Embryonic Fibroblasts (MEF) For Feeder Plates]
Gliotoxin is a metabolite of Aspergillus fumigatus that exhibits immunosuppressive activity against certain cells of the immune system. Secretion of gliotoxin during infection has been suggested as being a factor in the pathogenesis of aspergillosis. Gliotoxin secretion can be assayed in a number of ways by thin layer chromatography (TLC) high performance liquid chromatography (HPLC) or bioassay using the effect of gliotoxin on human cells1. - [Read Method for Assaying Gliotoxin Production in Aspergillus fumigatus Protocol]
For both biological and economical reasons, it is important to eliminate mycoplasmas from cell cultures being used for basic research, diagnosis, and biotechnological production. The most commonly used method for elimination, inactivation, or suppression of mycoplasmas in cell cultures is treatment with antibiotics. In general, antibiotic therapies do not result in long-lasting, successful elimination. Also, the cytotoxic properties of antibiotics can cause undesirable side effects on cells. - [Read Mycoplasma Elimination Reagent Protocol]

Protocol describes the production of double-stranded RNA (dsRNA) from fragments of cDNAs of candidate genes. The cDNA fragments must be cloned in plasmids with a flanking SP6 and T7 promoter (e.g., pSP72 or pCRII). The plasmid is linearized and sense and antisense RNAs are produced separately by in vitro transcription. After purification, the RNA strands are annealed to yield a dsRNA molecule suitable for RNAi in avian embryos. - [Read Production of dsRNA for RNAi in Avian Embryos Protocol]

Production of Mouse T Cell Hybridomas Protocol- https://catalog.invitrogen.com/index.cfm?fuseaction=iProtocol.unitSectionTree&treeNodeID=9E663496BA646F5C4FB54D6064E1A19B&objectid=6674C004CF35A9AC863EAD85BD9F080A
T cell hybridomas can be obtained by fusing activated T cells with tumor cells. A heterogeneous population of hybridomas can be cloned by limiting dilution to obtain hybridomas that express specificity to one T cell receptor (TCR). Protocol describes cell fusion and selection of T cell hybridomas. A protocol is provided for screening of T cell hybridomas for expression of the CD3-TCR complex by flow cytometry analysis. - [Read Production of Mouse T Cell Hybridomas Protocol]

Provides methods for the derivation of specific types of T cell clones: preparation and maintenance of alloreactive murine helper T (TH) lymphocyte and cytotoxic T lymphocyte (CTL) clones using the limiting dilution technique and derivation of TH clones reactive with soluble protein antigens including a method for the selection of either TH1 or TH2 lymphocyte subsets. - [Read Production of T Cell Clones Protocol]
In vitro transcription reactions employing T3, T7 or SP6 phage-encoded RNA polymerases are widely used to synthesize RNA from recombinant vectors containing appropriate promoters. Production of large amounts of specific RNA is valuable in the preparation of hybridization probes and in vitro translation studies; in the synthesis of ribozymes, rRNA, SRP, antisense RNA and substrates for RNA splicing; and in RNA-protein interaction studies. - [Read Protocol: Purification of In Vitro Synthesized mRNA with Microcon or Centricon Centrifugal Filters]
A Single Stranded Plasmid DNA Isolation Protocol describing the production and isolation of single-stranded DNA (ssDNA) using bacteriophagemid-containing bacteria and helper phage. Infection of the host cells with helper phage allows for packaging of ssDNA into bacteriophage. The ssDNA can then be isolated from phage particles.
This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.
