Claims (21)
1. Verfahren für die Retention eines durch die
Aktivität eines intrazellularen Enzym gebildeten
nachweisbaren Fluoreszenzreaktionsprodukts in
einer Zelle, wobei das Verfahren folgendes umfaßt:
a) Kontaktieren der Zelle mit einer biologisch
verträglichen Lösung, die ein Substrat der Form
XR-REPORTER-BLOCK
enthält, in der -BLOCK eine Gruppe darstellt, die
so gewählt wird, daß sie durch die Einwirkung des
Enzyms entfernt werden kann, wodurch man REPORTER
erhält, dessen spektrale Eigenschaften sich von
denjenigen des Substrats unterscheiden;
-REPORTER- ein Molekül darstellt, das, wenn es
nicht mehr durch eine BLOCK-REPORTER-Bindung an
BLOCK gebunden ist, über Spektraleigenschaften
verfügt, die sich von denjenigen des Substrats
unterscheiden; und
XR- einen Halogenalkylrest darstellt, in dem X Cl,
I oder Br darstellt und R 1-4 Kohlenstoffatome
enthält, der zu einer kovalenten Reaktion mit
einem intrazellularen Thiol (Z-S-K) unter Bildung
eines Thioetherkonjugats (Z-S-R-) fähig ist,
wobei die Zelle mit der biologisch verträglichen
Lösung unter Bedingungen kontaktiert wird, unter
denen das Substrat in intrazellulare Räume der
Zelle, die möglicherweise das Enzym enthält,
eintreten kann; und
b) Vorsehen eines genügend langen Zeitraums, damit
man durch Einwirkung des Enzyms BLOCK entfernt,
wodurch man REPORTER mit unterschiedlichen
Spektraleigenschaften erhält, und damit XR mit dem
intrazellularen Thiol unter Bildung des
Thioetherkonjugats innerhalb der Zelle reagieren
kann;
wobei das Verfahren gegebenenfalls folgende
weitere Schritte umfaßt:
c) Vorbereiten der Zelle für den Nachweis bzw. die
Messung der Fluoreszenz von REPORTER; und
gegebenenfalls
d) Durchführen dieses Nachweises bzw. dieser
Messung.
2. Verfahren nach Anspruch 1, in dem
a) BLOCK einen einwertigen Rest darstellt, der
durch Entfernung einer Hydroxygruppe von einem
Phosphat oder von einem Sulfat erhalten wird, oder
