Advantages of Gold Conjugates

• Sensitive technique (100pg or less in dot blotting when used together with our silver enhancement kit)
• This small gold nanoparticle conjugate is ideal for increasing sensitivity in immunohistochemistry protocols when used together with our silver enhancement kit for microscopy.
• Provides a permanent label

Storage/Stability

• Store undiluted in storage buffer at 2-8 degree Celsius. Stable for 4 months if stored as specified.
• Storage of conjugate at working dilution may result in performance loss.
