Add to Cart:
SpeedBlot (His) is a ready-to-use reagent for the detection of poly-histidine tagged proteins in blot assays. This reagent is equally suitable for Western Blot assays and Dot or Slot Blot assays.
The detection reagent is made of an optimized anti-histidine antibody gold nanoparticle conjugate and is reactive against C- and N-terminal tags. The protein of interest is specifically stained in pink directly on the blot. With this kit, the poly-histidine tagged proteins on nitrocellulose membrane with SpeedBlot (His) are easily detected and do not require relevant hands-on time. The highly sensitive detective reagent can even achieve 0.1 pmol detection limits.


  • Fast, simple four-step protocol
  • Specific staining of His-tagged proteins
  • Sensitive to sub-picomol amounts of protein
  • Simple incubation, no buffer exchange
  • No readout equipment required
