Isco’s pulseless constant power supplies eliminate the need for continual operator attention. They automatically provide maximum separation speed and sharpest zones, while greatly reducing the danger of overheating. Excellent regulation down to zero voltage, current or power, combined with unusually high power and current limits. For more information contact: Isco, Inc., PO. Box 5347, Lincoln, NE 66505, (600) 2264250.
LKB-Produkter AB, have launched the latest version of their Ultroscan XL laser densitometer, a high resolution instrument for all electrophoresis applications. The large 22 x 25 cm scanning area and easy to use track programming system permit scanning of either conventional 1-D gels or 2-D gels and autoradiographs. For more information contact: LKB-Produkter AB, Box 305, S-161 26 Bromma or your local LKB representatives worldwide.

Systec MICROSYN-1500
DNA Synthesizer
The MICROSYN-1500 DNA Synthesizer automates the rapid, efficient synthesis of oligonucleotides by any current method. The standard phosphite method produces coupling yields of 99% per step at a cycle time of 5 minutes. The instrument can synthesize at any scale from V4 to 10 $vl, for a minimum operating cost of $1 .OOper cycle. For more information contact: Systec, 3616 Chandler Drive, Minneapolis, MN 55421, (612) 7699701.
