Spreadsheet National Instruments Offers Updated Versions of LabVIEW Graphical Instrumentation Software Molecular Dynamics' Stand-Alone Confocal Software Antigenix Provides Human VCAM Antibody Reagent Hamamatsu Introduces Series of Photomultiplier Tubes Protein Analysis Kits For Capillary Electrophoresis Analtech Unveils Sample Application Device For TLC Bibliographic Data Software From PBS Spreadsheet Software Package The DADiSP graphical software and engineering spreadsheet package has been expanded with the release of three new add-on modules. DADiSP/AdvDSP 1.0 is a digital signal-processing (DSP) program that offers a variety of DSP algorithms, including advanced FFT analysis, power spectral density estimation, digital interpolation, and cepstrum analysis. DADiSP/Filters 3.0 is a digital filtering module that provides full finite impulse response (FIR) and infinite impulse response (IIR) filtering capabilities and includes Kaiser Window filtering. DADiSP/Neural Net enables users to build and train backpropagation neural networks, which facilitate pattern-recognition tasks involving multidimensional datasets. DSP Development Corp., Cambridge, MA Circle No. 190 on Reader Service Card Graphical Instrumentation Software LabVIEW Version 3.1 is the latest upgrade to National Instruments' graphical instrumentation software for Windows PCs, Macintosh computers, Sun SPARCstations, and Hewlett-Packard 9000 Series 700 workstations. It features new configuration-management tools; direct calls to dynamic-link libraries (DLLs) and shared libraries; new capabilities for automated test equipment and process-control needs; and various editing, debugging, and online help features. LabWindows/CVI Version 3.0.1 is designed for developers and experienced C programmers interested in using interactive C programming to build instrumentation systems. The software enables users to automatically create stand-alone executable programs and distribution kits with installer programs. National Instruments, Austin, TX Circle No. 191 on Reader Service Card ImageSpace 3.1 confocal software for three-dimensional visualization and 3-D quantitation is now available as a separate program with import routines for images from all confocal systems. The software, previously available only as part of the company's Confocal laser scanning microscope systems, offers an integrated environment for rendering, processing, analyzing, and displaying confocal images with an intuitive graphical user interface. Its analytical capabilities include automated object counting, seeding, and segmentation; it also features tools for quantitative co-localization studies. Molecular Dynamics, Sunnyvale, CA Circle No. 192 on Reader Service Card The new monoclonal antibody reagent is specific for human vascular cell-adhesion molecule (VCAM-1). This antibody has recently been clustered to CD106, and reacts with lymphocytes, fibroblasts, monocytes, neural crest cells, and other cell types. The reagent inhibits cellular adhesion and has applications in functional studies, immunohistochemistry, and ELISA development. It is supplied as a highly purified monoclonal antibody and is directly conjugated to FITC or R-PE. Antigenix America Inc., Franklin Square, NY Circle No. 193 on Reader Service Card The R3809U series of microchannel plate photomultiplier tubes (PMTs) are designed for use in molecular-structure analysis, optical computer tomography, fast gene sequencing, semiconductor analysis, crystal research, and other applications. They have rise times of 150 picoseconds (ps) and transit time spread (TTS) of 25 ps. Seven standard models cover various bandwidths from 115 nm to 1,200 nm. The tubes are supported by a range of accessories, including a thermoelectric cooling unit, PMT holder, high-speed 50-kHz-to-1.5-GHz amplifier, and high-voltage power supply. Hamamatsu Corp., Bridgewater, NJ Circle No. 195 on Reader Service Card The MicroCoat Protein Analysis Kit contains a reagent that produces a positively charged surface by coating the capillary wall, thereby permitting free migration of proteins through the capillary and subsequent detection. The kit includes this charge-reversal reagent, capillaries, a neutral marker, standards, and a protocol. The ProSort SDS-Protein Analysis Kit is designed to eliminate gel preparation, staining, and other labor-intensive requirements of the standard SDS-PAGE method. Proteins ranging from 14 to 205 kilodaltons can be separated in one run. The kit also facilitates glycoprotein separations. Perkin-Elmer Corp., Norwalk, CT Circle No. 196 on Reader Service Card The AUTOSPOTTER is a semiautomated device for applying samples on thin-layer chromatography (TLC) plates. It can apply up to 18 samples at a time at variable rates, using TLC syringes with blunt, Teflon-tipped needles. Solvent evaporation is aided by an integral heater strip that runs beneath the TLC plate at the point of sample delivery. Small sample zones may be obtained through adjustment of delivery rate and heater strip temperature. Analtech Inc., Newark, DE Circle No. 197 on Reader Service Card BiblioLink II Version 1.0.1 for Windows and Version 1.1 for Macintosh are utility programs for ProCite reference-management software. BiblioLink II uses configuration files to transfer bibliographic records, downloaded from various secondary information services, into a ProCite database. The records can then be searched, sorted, and printed in any bibliographic style. The software's configuration files are designed for the most commonly used bibliographic reference databases. Researchers can also create their own configuration files for other electronic databases. Personal Bibliographic Software Inc., Ann Arbor, MI Circle No. 194 on Reader Service Card
