Ten procedures for thin-layer chromatography of carbohydrates in urine were compared. The procedures differ considerably in their sensitivity and ability to separate sugars of clinical importance. A procedure was developed that permitted several sugars to be identified in normal urine samples without prior desalting or concentration. Celite was used as adsorbent, anisaldehyde as location reagen...

Granulicella tundricola hydroxynitrile lyase (GtHNL) catalyses the synthesis of chiral (R)-cyanohydrins and (R)-β-nitro alcohols. The triple variant GtHNL-A40H/V42T/Q110H (GtHNL-3V) was immobilised on Celite R-633 used in monophasic MTBE saturated with 100 mM KPi buffer pH 7 for (R)-2-nitro-1-phenylethanol (NPE) batch continuous flow systems. Nitromethane as a nucleophile. A total 82% (R)-NPE e...

Celite Corporation and Andersen Consulting have developed an advanced approach to traditional software development entitled the Application Software Factory (ASF). The approach is an integration of technology and Total Quality Management techniques which includes the use of an expert system to guide module design and perform module programming. The expert system component is called the Knowledg...

Methods of platelet adhesiveness to glass and celite have been developed. The technical merits of these methods have been compared with a method using adenosine diphosphate (ADP). The aspects of platelet stickiness measured by the various techniques may be somewhat different. Bearing this in mind, the reproducibility of the results using each of the three methods has been assessed on a series o...

1. A dextran synthesized by Leuconoatoc mesenteroides (strainNRRL B-512) has been partly hydrolysed with acid and the products were fractionated on charcoal-Celite. 2. Glucose was the only monosaccharide product and the dito hexa-saccharide fractions each contained a single component. 3. The oligosaccharides have been characterized as the lower members of the isomaltodextrin series and new crys...

The conventional plasma recalcification test is improved by incubation of test plasma with Celite suspended in distilled water. This effectively activates factor XII and releases platelet factor 3, thereby markedly shortening the clotting time. The modified plasma recalcification test has several advantages that contribute to its usefulness as a general screening test for coagulation abnormalit...
