Cytosolic Tracers & Related Reagents

PromoKine offers a number of polar, membrane-impermeant fluorescent dyes and related products for cell tracing applications. These highly positively-charged or negatively charged probes can be introduced into cells by microinjection. Alternatively, some of the probes bearing carboxylic acid groups have been derivatized into non-polar acetoxymethyl (AM) esters, which can easily enter cells and then become rapidly hydrolyzed by endoesterases into the original polar dyes.
