The new PointProbe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a further reduced and more reproducible tip radius as well as a more defined tip shape. The excellent tip radius and the minimized variation in tip shape provide more reproducible images and enhanced resolution.
The FM type is offered for force modulation microscopy. The force constant of this AFM probe spans the gap between contact and non-contact mode and is specially tailored for the force modulation mode. The FM probe serves also as a basis for magnetic coatings (MFM). Furthermore non-contact or tapping mode operation is possible with the FM tip but with reduced operation stability.
For certain applications the rotated PointProbe® Plus Tip offers more symmetric imaging. The rotated tip shape is identical to the classic tip shape but it is rotated by 180° degrees with respect to the cantilever beam direction.
The probe offers unique features:
excellent tip radius of curvature
highly doped silicon to dissipate static charge
high mechanical Q-factor for high sensitivity
precise alignment of the cantilever position (within +/- 2 µm) when used with the Alignment Chip
compatible with PointProbe® Plus XY-Alignment Series
The reflex coating is an approximately 30 nm thick aluminum coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the cantilever. The virtually stress-free coating is bending the cantilever less than 2% of the cantilever length.

AlleleID. It is designed to address the challenge of pathogen detection, species identification and taxa discrimination using TaqMan and molecular beacon assays. With ClustalW multiple sequence alignment at its core, AlleleID can help design universal or taxa/species specific primers and probes. All major qPCR assays including molecular beacons, TaqMan, FRET or SYBR Green are supported. It uses BLAST search to assure specificity. To assure assay success, AlleleID uses template folding to avoid locating primers in the secondary structures of the template.
With AlleleID, you can avoid gDNA by designing primers/probes across exon/exon boundaries. The intron exon regions are identified by interpreting GenBank annotations or by specifying them manually.
To get started quickly with AlleleID, please download and listen to the multi-media tutorial: http://www.PremierBiosoft.com/DATAFILES/AL100Tour.exe.
