LAS 4000 Imager

As of Dec 1, 2015, all appointments must be made using FOM. This site's calendar is no longer in use.

The LAS-4000 is an image analysis system that can detect chemiluminescence, bioluminescence and fluorescence with cooled CCD camera using a 3.2 megapixel super CCD. The exposure time ranges from 1/100 sec to 2 hours. It has a dynamic range of up to four orders of magnitude. It is regularly used to take images of Western blots and SDS PAGE gels and it can also detect GFP and EtBr signal.

QSense E4 Quartz Crystal Microbalance

As of Dec 1, 2015, all appointments must be made using FOM. This site's calendar is no longer in use.

Q-Sense E4 Auto is an automated, real-time, analytical instrument for studying molecular events occurring on surfaces. The E4 Auto measures mass and viscoelastic properties of molecular layers as they accumulate or change on the chosen sensor surface. Information on Q-Sense can be found at http://www.q-sense.com/.

Crystals are sold separately as follows:

SiO2: $100 each

Gold: $60 each
