Size: 3 vials

CytoGroup AptamerREADY™ Gold Nanoparticle Conjugation Kits have been optimized for high efficiency one-step conjugation of thiolated aptamers directly to the gold surface. 

The kit contains ready-to-use pre-made mixtures. No activation, manipulation or time consuming "salt-aging" steps are required for conjugation. Simply mix your thiol-modified aptamer with the pre-activated gold nanoparticles supplied in the kit. Conjugation of the aptamer is achieved by the formation of a strong and stable gold-thiol bond. 

Kit Components

  • 3 vials or 10 vials of 20nm AptamerREADY™ Gold Nanoparticles (lyophilized) - Sufficient for generation of 3 x 0.2 ml or 10 x 0.2 ml gold conjugate at OD=10

Features & Benefits

  • Results in thiol-aptamer bound directly to the gold surface through a stable thiol-gold bond.
  • Fast and convenient one-step conjugation reaction with no pre-activation requirements.
  • Does not require time consuming salt aging procedures saving you valuable research time.
