Substrate for HaloTag®*: allows bright, far-red fluorogenic visualization of HaloTag®fusion protein of interest (POI) in live or fixed cells and tissues
SPY700-CA (also called Map700-Halo) is a ChloroAlkane (CA) derivative of the SPY™ fluorophore. CA is the substrate for HaloTag®, which forms a covalent bond upon reacting with it. This enables the permanent labeling of any POI that is expressed as a HaloTag® fusion, allowing stable fluorescent imaging of your POI in live or fixed cells.
