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]

Category: Signalling Signal Transduction Protocols

This protocol describes assaying kinase activity of a putative kinase using Histone H1 as the substrate. Histone H1 is the canonical kinase substrate in this type of assay. Phosphorylation of Histone H1 is assessed by SDS-Polyacrylamide gel electrophoresis followed by autoradiography. Includes information: H1 Kinase Assay on Individual Xenopus Oocytes; H1 Kinase Assay on Xenopus Egg Extract Samples; H1 Kinase Assay on Tissue Culture Cells; Helpful protocol hints. - [Read Histone H1 Kinase Activity Assay]

Category: Immunology: Immunoprecipitation Protocols

Protocol for immunoprecipitation of mRNA-protein complexes. In this protocol, an antibody targeting an RBP of interest is used to immunoprecipitate the RBP and any interacting molecules from a cell lysate. Reverse transcription followed by PCR is then used to identify individual mRNAs isolated with the RBP. This method focuses on examining an association between a specific RBP-mRNA complex, and it is best suited for a small scale screening of known or putative binding partners. - [Read Immunoprecipitation of mRNA-Protein Complexes Protocol]

Category: Plant Biology Protocols: Arabidopsis Transformation Protocols

Protocol for vacuum-infiltration transformation of Arabidopsis thaliana. Includes: Plant Growth; Vacuum Infiltration; Selection of Putative Transformants; Kanamycin selection. - [Read Vacuum-Infiltration Transformation of Arabidopsis thaliana Protocol]
