WebArguably the simplest affinity tag is the polyhistidine (His) tag. Small and unlikely to affect function, His-tagged proteins can be purified using metal-affinity chromatography, usually using a Ni2+ column. Like other affinity … Tandem affinity purification (TAP) is an immunoprecipitation-based purification technique for studying protein–protein interactions. The goal is to extract from a cell only the protein of interest, in complex with any other proteins it interacted with. TAP uses two types of agarose beads that bind to the protein of … See more This tag is also known as the C-terminal TAP tag because an N-terminal version is also available. However, the method to be described assumes the use of a C-terminal tag, although the principle behind the method is still the … See more TAP tagging was invented by a research team working in the European Molecular Biology Laboratory in the late 1990s (Rigaut et al., 1999, … See more An advantage of this method is that there can be real determination of protein partners quantitatively in vivo without prior knowledge of complex composition. It is also simple to … See more As this method involves at least 2 rounds of washing, it may not be suitable for screening transient protein interactions, unlike the yeast two-hybrid method or in vivo crosslinking with photo-reactive amino acid analogs. However, it is a good method for testing … See more There are a few methods in which the fusion protein can be introduced into the host cells. If the host is yeast, then one of the methods may be … See more However, there is also the possibility that a tag added to a protein might obscure binding of the new protein to its interacting partners. … See more In 2002, the TAP tag was first used with mass spectrometry in a large-scale approach to systematically analyse the proteomics of … See more
