Adaptors are short double-stranded synthetic oligonucleotides that carry an internal restriction endonuclease recognition site and single-stranded tails at one or both ends. Adaptors are used to exchange restriction sites at the termini of linear DNA molecules. They may be purchased in phosphorylated and unphosphorylated forms. - [Read Attaching Adaptors to Protruding Termini Protocol]

Most powerful and convincing method to determine if a specific protein is phosphorylated in a physiologically relevant manner is to assay phosphorylation in situ. The procedure described involves incubating cultured cells (e.g., primary neuronal cultures or transfected cells) or tissue preparations (e.g., hippocampal slices) with [32P]orthophosphate, which is then taken up by the cells or tissues and incorporated into the γ-phosphate position of ATP. - [Read Detection of Protein Phosphorylation in Tissues and Cells Protocol]

Novel strategy of immunizing a phosphorylated peptide or a synthetic phosphopeptide, which corresponds to the protein phosphorylated at a targeted residue. Method has been applied to the production of antibodies that can specifically recognize the other types of site-specific protein modification, such as acetylation, methylation, and proteolysis. - [Read Functional Analyses for Site-Specific Phosphorylation of a Target Protein in Cells]

Protocol presents a method that allows rapid determination of the monosaccharide composition of glycans, glycoproteins, and proteoglycans that contain (or are suspected to contain) phosphorylated sugars.  (For samples that do not contain phosphorylated sugars see Monosaccharide Analysis by Methanolysis.) - [Read Monosaccharide Analysis of Phosphorylated Sugars by Methanolysis and Diazomethane Methylation]

Detection of phosphorylated tyrosine residues can be performed using anti-P-TYR Ab and Western Analysis.Includes 2nd method,which uses phosphotyrosine in conjunction with anti-P-TYR Ab to "unlabel" potential proteins.By comparing Westerns developed with the 1st method(reveals phosphorylated protein) and the 2nd method(reveals non-specific labeling), a more accurate picture of those proteins phosphorylated on tyrosine can be seen. Includes: Protein Preparation, Electrophoresis and Transfer. - [Read Protocol for Antiphosphotyrosine Western Blot Analysis]
