HisDetector products utilize patented nickel-NTA enzyme conjugates that bind with high affinity to His-tagged recombinant proteins. They provide a reliable method for direct detection of His-tagged proteins without the use of antibodies, and can save two hours in a Western blot procedure when compared to traditional antibody methods. A strong, specific signal is produced with very low background. HisDetector Western Blot Kits contain all the reagents necessary for rapid detection of His-tagged proteins using a simple protocol. A variety of detection formats allow flexibility in choice of chemiluminescent or colorimetric detection with either HRP or AP Nickel Conjugates; conjugates are also available separately and can be used in a variety of assays to detect His-tagged proteins.
