Tech Info

GKK-404 Technical Data Sheet  


Q. Can GKK-804 be used as a direct replacement for GKK-404?

A. Yes. After combining the reagents as directed, the final formulation of the 2-AB labeling reagent is the same for both GKK-404 and GKK-804. We have supplied a Quality Memo to confirm this.

GKK-804 offers a few advantages over the older GKK-404 kit: there are no glass ampoules, no reconstitution, you can use what you need and store the rest at -20C for up to 6 months.
