Our products

Product category: Diagnostic rapid tests

High Sensitivity Gold Conjugation Kit

  • Increase assay sensitivity up to 20× with Gold Nanoshells as compared to 40 nm gold 
  • Detailed procedure for ease-of-use 
  • Quickly screen through different conjugate conditions
  • Pre-validated reagents and buffers to perform multiple conjugations 
  • Conjugate stability with a wide range of sample matrices
The High Sensitivity Conjugation Kit is a complete solution with detailed protocols to help you produce robust covalently-bound conjugates. This kit is available with our ultra-bright 150 nm Gold Nanoshells as the reporter particle and includes everything you need to optimize your conjugations.

Colloidal Gold for Passive Conjugation

  • 40 nm and 80 nm sizes for passive adsorption 
  • Increased binding efficiency with citrate and carbonate surfaces
  • Compatible for conjugation at a wide range of pHs
  • Excellent batch-to-batch consistency
  • Available in high OD and bulk quantity for scale-up and manufacturing 
Our classic 40 nm and 80 nm “bare” gold nanoparticles are stabilized with weakly-associated citrate or carbonate molecules that can be easily displaced for better passive adsorption with antibodies, antigens, or oligonucleotides. Our colloidal gold is available at high concentrations and multiple batches for lot validation/reservation and manufacturing. Contact us for free samples and bulk pricing.

NHS-Activated 40 nm Gold and 150 nm Gold Nanoshell Kits

  • Save time and materials cost with pre-activated NHS gold for quick screening of particles  
  • Available with 40nm spheres and 150nm Gold Nanoshells
  • Detailed instructions and easy to use
NHS pre-activated gold is provided dried with conjugation kit components that make initial conjugation evaluation easy – no EDC/NHS activation required – just add purified antibody and follow our simple protocol.

Streptavidin Conjugated Gold

  • Strong avidin-biotin bond for rapid and robust conjugation to biotinylated reagents 
  • Conjugate ready in less than 1 hour 
  • Available with 40 nm gold spheres or 150 nm Gold Nanoshells
Streptavidin tetramer is covalently bound to the particle surface via an amide bond. Streptavidin gold conjugates can be used for convenient conjugation of any biotinylated antibody, protein or oligonucleotide.
