Coimmunoprecipitation is one of the most useful techniques for revealing protein-protein interactions. Good negative controls to verify the specificity of the coimmunoprecipitation procedure are (1) performing the same immunoprecipitation experiment using beads coupled to the preimmune serum and (2) probing the Western blot with antibodies against protein known not to interact with the coimmunoprecipitated proteins under physiological conditions. - [Read Protein Coimmunoprecipitation in Arabidopsis Protocol]

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]

Procedure describes how it denatures most of the modification and degradation proteins immediately giving the most accurate read out of the true levels of protein at the time of harvest. However, in cases where detection is a problem, a limited purification (e.g. isolation of nuclear extract for the detection of transcription factors) might be required to allow analysis. - [Read Western Blot Analysis of Endogenous Gene Expression Protocol]
This protocol describes nuclear and cytoplasmic fractionation of tissue culture cells and a method for Western blot detection of proteins using the Odyssey Infrared Imaging System. This protocol was used to detect expression of the "small" Tap protein in 293T, HeLa and COS cells. The Odyssey system has several advantages over the more widely used chemiluminescent detection methods. - [Read Western Blot Analysis of Sub-Cellular Fractionated Samples Using the Odyssey Infrared Imaging System]
