FLAG® Immunoprecipitation Kit



ANTI-FLAG® M2 Affinity Gel

General description

TAP technology is a recent development in protein purification. This technology incorporates tandem-linked affinity tags into genes of interest so that high purity fusion proteins can be isolated through two consecutive affinity purification steps. The technology is particularly useful for the isolation and identification of protein complexes by adding a tandem affinity tag to a known "bait" protein to pull down endogenous proteins that interact with the targeted protein of interest.


The FLAG® HA Tandem Affinity Purification Kit is designed for the isolation of high purity FLAG-HA dual-tagged fusion proteins from complex matrix, such as cell lysates and tissue homogenates. The kit is particularly suitable for isolation of protein complexes using TAP (Tandem Affinity Purification) technology.

Sutitable for mass spectrometry analysis and western blotting.

The FLAG® HA tandem epitope system consists of small epitopes tags that are not eukaryotic derived. These features minimize interference with protein functions and provide superior specificity.
