Abstract: A method for preparing saccharide compositions is disclosed. The method is reiterative and comprises the following three steps.

Abstract: Processes for preparing oligosaccharides, polysaccharides, glycolipids, glycoproteins, and other saccharide compositions are provided which involve the enzyme facilitated transfer of a preselected saccharide unit from a donor moiety to an acceptor moiety. In accordance with a preferred embodiment, saccharide compositions having a plurality of saccharide units are prepared by appending the saccharide units in iterative fashion to acceptor moieties which are themselves saccharide compositions prepared in accordance with this invention.

Abstract: A method for preparing saccharide compositions is disclosed. The method is reiterative and comprises the following three steps. (i) A glycosyltransferase capable of transferring a preselected saccharide unit to an acceptor moiety is isolated by contacting the acceptor moiety with a mixture suspected of containing the glycosyltransferase under conditions effective to bind the acceptor moiety and the glycosyltransferase and thereby isolate the glycosyltransferase. The acceptor moiety is a protein, a glycoprotein, a lipid, a glycolipid, or a carbohydrate. (ii) The isolated glycosyltransferase is then used to catalyze the bond between the acceptor moiety and the preselected saccharide unit. (iii) Steps (i) and (ii) are repeated a plurality of times with the intermediate product obtained in the first iteration of the method being used as the acceptor moiety of the second iteration.

Abstract: A method is disclosed for optimally adjusting the received bit detection threshold in a digital communication system, such as a TDMA system that is characterized by very short duration burst transmissions. In one embodiment of the invention, a half-duplex radio modem is used for transmission and receipt of messages for airborne and ground-based Automatic Dependent Surveillance-Broadcast (ADS-B) service. A feedback path is provided for in the transmission/receiver unit to provide the transmission signal to the receiver path. A bit detection threshold adjustment circuit receives the transmission signal. The circuit digitizes the analog baseband signal, detects the positive and negative peak values and calculates a peak-to-peak deviation value to define the bit detection threshold value.
