Electron Microscopy Sciences Em Goat/Human Igg, Ultra Small

Electron Microscopy Sciences Aurion ultra small immunogold reagents are prepared with subnanometer gold particles. These particles have far less influence on the adsorbed antibodies or detecting molecules, and consequently the conjugates behave as though they are uncoupled. In conjunction with the highly efficient and easy-to-use r-gent se-lm and se-em silver enhancement reagents, the ultra small immunogold reagents are the best choice for any application. Reduction of the gold particle size provides ultra small immunogold reagents with fundamentally different characteristics when compared with conjugates built around larger particles. While the conventional immunogold reagents can be thought of as particles coated with proteins, ultra small immunogold reagents are proteins coated with one or more gold particles. With this structure, both the overall size of the conjugates, as well as steric hindrance are decreased. - EMS (Additional S&H or Hazmat Fees May Apply)
