* 酶动力学(Enzyme Kinetice)

* 底物结合(Substrate Binding)

* 构象转变(Conformational Changes)

* 胞内底物运输(Substrate Transport in Vesicles)

* 第二信使研究(Second Messenger Studies)

* 快速化学反应动力学(Rapid Chemical Reaction Kinetics)

KinTek has always been aleader in building stopped-flow instrumentsthat conserve precious samples. The all new AutoSF-120 sets a new standard for sample economy requiringonly 120 microliters of sample to flush load and collect data while giving with 3-4 replicate measurements.The flushing and sample loading areall done automatically. Simply pipette 120 microliters of solution into each sample cup and click "Load".

In the process of designing this new state-of-the-art instrument we also added new noise reduction electronic circuits to improve signal:noise twofold and achieved asubmillisecond dead time. In addition we completely re-wrote the system software for data collection and analysis to give unparalleled ease of use and power.

The KinTek AutoSF is by far the best stopped-flow instrument ever built giving you more high quality data while consumingless sample and less time.

An optionalrobotic autosamplerincreases throughput even more to afford unattended stopped-flow measurements ofhundreds of samples per day.

  • Small sample volume:120 L is sufficientto flush and load a new sample and get3-4 reproducible shots.All other instruments require 3-5 times as much sample.

  • Automated computer-controlledload/flush/fire cycle simply pipet 120 L into each sample cup and click "load".

  • Twofold improvement in signal/noise with new noise reduction circuits

  • Compact footprint: instrument and electronics combined (14 26.5 4.5 inches)

  • Computer optimized optical path with lower noise and background fluorescence

  • Automated sample loader which can be interfaced with an optional robot.

  • 200 l of sample is sufficient to load and collect 6-8 good shots.

  • Standard 10 l flow cell.

  • 20 l per shot per solution.

  • Hastwo fluorescence channelsandone absorbance channelthat can be observed and recorded simultaneously.

  • Under complete computer control courtesy of the KinTek StopFlow Software.
