SYNOSTAT Ρ automatically synthesizes peptides using pre-programmed strategies including FMOC and t-BOC. Synthesis scales range from 0.1 to 5 mmol. Eppendorf 418
Software Data analysis. Unscrambler II software finds and describes the variations within one set of data (one matrix) or the variations and correlations between two sets of data (two matrices). The software is designed for IBM PC XT/ATs and compatible computers without limitations on the number of matrix elements. Camo AS 419
NMR. WIN-NMR software, for Macintosh computers, is designed to pro
cess NMR data. Routines for Fourier transformation, phasing, deconvolu-tion, integration, split-screen operat ion, and p lo t t ing are inc luded. Bruker Instruments 420
Manufacturers' Literature B i o m o l e c u l e s . Three application notes describe how the SMART system purifies nanogram and low-microgram quanti t ies of receptors, neuroactive substances, and DNA. Pharmacia LKB Biotechnology 421
HPLC. Troubleshooting guide discusses ways to avoid injection problems with Rheodyne injectors. Special a t tent ion is given to artifact peaks, nonreproducible results, decreased system pressure, blockage, noise or drift, and leaks . 34 pp. HPLC Technology 422
Catalogs Life s c i e n c e s . Cata log inc ludes products for HPLC, electrophoresis, immunochemistry, and molecular biology. Applications data and a poster
