pHast Conjugates
pHast Conjugates are one of our pHastest tools for quantitative testing of your primary antibody’s specificity, binding, and internalization, providing results in 1 day.
How It Works
The pHast conjugate binds to your primary antibody via a secondary antibody cross-linked to a pH-dependent fluorescent reporter. This fluorescent reporter will increase intensity as the pH of its surroundings becomes more acidic, as evident when exposed to the environment inside a cell. pHast conjugates are fluorescent plate reader compatible and can be used to illuminate your lead antibody candidates in a 96-well plate format.
Also Available:
Streptavidin-pHast (PH-03)
Streptavidin-pHast binds to your biotinylated protein and contains a pH-dependent fluorescent reporter (pHast).
