The AfCS is utilizing antisense technology to manipulate signaling protein expression in the RAW 264.7 macrophage-like cell line. This can be achieved by the transfection of gene-specific antisense oligonucleotides (ASOs). The following procedure involves the transfection of ASOs into RAW 264.7 cells using FuGENE 6 transfection reagent. Subsequently, the isolated total RNA or protein from these transfected cells can be used to assess the level of mRNA or protein knockdown, respectively. - [Read Antisense Oligonucleotide Transfection of RAW 264.7 Cells with FuGENE 6 in a 24-Well Dish]

Serum concentrations of itraconazole should be measured in patients receiving this drug to ensure that therapeutic concentrations are being achieved. This is necessary as drug absorption can be variable, and levels may be lowered by interactions with other drugs. The assay will give an indication of whether suitable blood levels have been achieved. - [Read Bioassay for Determining Itraconazole Levels in Blood]

Protocol for Colorimetric Assay to Identify Putative Ribofuranosylaminobenzene 5'-Phosphate Synthase Genes. The production of active RFAP synthase from Methanothermobacter thermautotrophicus was achieved by coexpression of the gene MTH0830 with a molecular chaperone. This is the first direct biochemical identification of a methanogen gene that codes for an active RFAP synthase. - [Read Colorimetric Assay to Identify Putative Ribofuranosylaminobenzene 5'-Phosphate Synthase Genes]

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]

Transfer of proteins from a Tris/glycine SDS-polyacrylamide gel to a membrane using the submerged method is achieved by placing the gel next to a piece of nitrocellulose filter, submerging this sandwich in a large volume of transfer buffer in a transfer tank, and running current from one side of the transfer tank to another.  The proteins are then eluted by transferring them from the gel onto the filter. - [Read Immunoblotting: Submerged Electrophoretic Transfer of Proteins from Gels to Membranes Protocol]

Protocol for screening immobilized dyes for their ability to bind a target protein. The selection of a dye adsorbent for the purification of the target protein is an empirical undertaking and is generally achieved by a trial-and-error approach. - [Read Screening Immobilized Dyes for their Ability to Bind a Target Protein Protocol]

Protocol describes a method for the delivery of siRNAs into mammalian cells in the absence of reporter plasmids. This is best achieved with transfection reagents developed for the delivery of antisense oligodeoxynucleotides. The quantities of reagents given below are calculated for the transfection of one well of a 24-well plate. - [Read Transfection of Mammalian Cells with siRNA Duplexes Protocol]
