The Thermo Scientific SuperSignal West HisProbe Kit contains HisProbe-HRP Conjugate, as well as reagents required for detection of polyhistidine-tagged protein by western blotting. HisProbe-HRP Conjugate is a nickel (Ni2+)-activated derivative of horseradish peroxidase (HRP) that enables direct, IMAC-based detection of His-tagged proteins.

Features of the SuperSignal West HisProbe Kit:

Fast—His-tag detection is achieved with a one-step probe incubation that eliminates the need to run a lengthy two-step primary/secondary antibody reaction protocol
Economical—no need to purchase expensive primary/secondary antibodies; considerably less costly than anti-6xHis-tag antibodies
High specificity—HisProbe-HRP can recognize his-tags independent of adjacent tags.
Less steric hindrance—HisProbe-HRP is smaller than antibodies and detects his tagged fusion proteins that are often undetectable when using some anti-his-tag antibodies

Unlike anti-6xHis antibodies, HisProbe-HRP can recognize polyhistidine tags independent of adjacent tags. The active ligand in HisProbe-HRP is a tridentate chelator that allows Ni2+ to be bound in active form for subsequent interaction and detection fo target molecules. The active chelator has binding capabilities similar to iminodiacetic acid (IDA) when used for immobilized metal affinity chromatography (IMAC). The Thermo Scientific SuperSignal West HisProbe Kit includes blocking buffers and chemiluminescent substrate for sensitive Western blot detection via the HisProbe-HRP Conjugate.
