BirA Biotin Ligase, GST-tag 

Amid Biosciences offers BirA Biotin Ligase enzyme, expressed with an N-terminal 6XHis and glutathione S-transferase (GST) dual tag in E. coli. The dual 6xHis-GST tag allows removal of BirA enzyme after biotinylation reaction using either Ni-NTA or glutathione agarose resin columns.

Ideal for precise and efficient protein biotinylation, this BirA biotin ligase is crucial for applications requiring selective labeling of proteins. Whether you're performing in vitro or in vivo biotinylation, our BirA enzyme offers reliable performance and ease of use for all your molecular biology needs.
