The Rabbit anti GST-Tag Polyconal Antibody (CABE006) is a high-quality antibody developed for reliable detection and analysis of target proteins. This polyclonal antibody, raised in rabbits, is highly specific and sensitive for detecting GST-tagged proteins in various experimental applications such as Western blotting and immunoprecipitation.The GST tag is frequently used in recombinant protein research for easy purification and detection of target proteins. This antibody specifically recognizes the GST tag, allowing for efficient detection and analysis of GST-tagged proteins in cell lysates, protein extracts, and other experimental samples.
This antibody is validated for use in WB, IP applications and has demonstrated reactivity against Species independent samples.

Glutathione S-transferases (GSTs), previously known as ligandins, comprise a family of eukaryotic and prokaryotic phase II metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione (GSH) to xenobiotic substrates for the purpose of detoxification. The GST family consists of three superfamilies: the cytosolic, mitochondrial, and microsomal—also known as MAPEG—proteins. Members of the GST superfamily are extremely diverse in amino acid sequence, and a large fraction of the sequences deposited in public databases are of unknown function. The Enzyme Function Initiative (EFI) is using GSTs as a model superfamily to identify new GST functions.A GST-tag is often used to separate and purify proteins that contain the GST-fusion protein. The tag is 220 amino acids (roughly 26 KDa) in size, which, compared to tags such as the Myc-tag or the FLAG-tag, is quite large. It can be fused to either the N-terminus or C-terminus of a protein. However, many commercially available sources of GST-tagged plasmids include a thrombin domain for cleavage of the GST tag during protein purification.
