Nano-activeGold™ is a newly developed gold immunoprobe. Nano-ActiveGold™ reagent consist of Streptavidin covalently conjugated to the 1.5 nm Nano-activeGold™ cluster label.
Nano-activeGold™ can be used in immunoblotting, light microscopy, and electron microscopy to provide clear visibility.
For research use only. Not recommended or intended for diagnosis of disease in humans or animals. Do not use internally or externally in humans or animals. Non radioactive and non carcinogenic.
- Smallest commercially available gold immunoprobes.
- Penetrates and reaches antigens inaccessible to other probes.
- Extremely uniform 1.5 nm diameter gold label.
- Low non-specific affinity gives minimal background.
- Ultrasensitivity with silver enhancement: 0.1 pg of antigen detection on immunoblots.
- Gold covalently attached to streptavidin.
- High stability and long shelf life.
- Stable to a wide range of pH and ionic strengths.
Supplied in 20 mM phosphate buffered saline (150 mM NaCl) at pH 7.4, with 0.1 % BSA and 0.05 % sodium azide.
