Tips for selecting the “right” ELISPOT filter plate and making the best protocol choices

 Nitrocellulose or PVDF? There are two different types of membranes (in 96-Well plate formats) that are used in ELISPOT applications: Nitrocellulose (NC) and polyvinylidene fluoride (PVDF). The reason that these are the predominant membrane types used in ELISPOT is based largely on their fortuitous suitability in non-ELISPOT applications rather than on the development of optimized assay substr...

Nanoindentation of compliant materials using Berkovich tips and flat tips

Nanoindentation testing of compliant materials has recently attracted substantial attention. However, nanoindentation is not readily applicable to softer materials, as numerous challenges remain to be overcome. One key concern is the significant effect of adhesion between the indenter tip and the sample, leading to larger contact areas and higher contact stiffness for a given applied force rela...

WYSIWYG-Tool Tips: Enhancing Tool Tips with Translucent Preview Bitmaps

This paper suggests to enhance the concept of tool tips by presenting translucent preview bitmaps. The basic idea is to give the user a preview of what would happen when a certain operation is invoked. We have implemented two prototypes to evaluate the concept. One provides WYSIWYG (What You See Is What You Get) tool tips for documents and applications on the desktop. The second one is an appli...
