Dip and Read™ Anti-Penta-HIS (HIS) Biosensors
For Label-Free Quantitation of HIS-Tagged Proteins

The poly-histidine protein tag (HIS-tag), commonly engineered into proteins during cloning, can be used to facilitate recombinant protein purification and detection by exploiting the chelating properties of histidine to an immobilized metal. The Anti-Penta-HIS biosensor, with a factory immobilized form of QIAGEN's highly specific anti-HIS antibody, now provides a rapid and direct method for quantifying HIS-tagged proteins in crude lysates using the Octet^® platform in an “out of the box” format.

Key Features

• Quantitate proteins containing a six-histidine or penta-histidine peptide tag (HIS-tag)
• Designed for use in buffer, complex media, column eluates, and cell lysates
• Binds HIS-tagged proteins even in the presence of imidazole
• Easy to use, label-free, no wash protocol
