A-Galactosyl

Ricin (toxin from Castor bean Ricinus communis) [A chain 96638-28-7 B chain 96638-29-8] Mr -60,000, amorphous. Crude ricin, obtained by aqueous extraction and (NH4)2S04 pptn, was chromatographed on a galactosyl-Sepharose column with sequential elution of pure ricin. The second peak was due to ricin agglutinin. [Simmons and Russell Anal Biochem 146 206 1985.) Inhibitor of protein synthesis. EXTREMELY DANGEROUS, USE EXTREME CARE [instructions accompany product]. 

Artificial glycopolymers having a-galactosyl epitope are of interest from the viewpoint of medical transplantation of pig liver since they can block im-... 

For GLS, the headgroup is a galactosyl-3-sulfate-P-D-l— 6-mannosyl-a-D-l— 2-glucosyl moiety. Adapted from refs. [25,26],... 

As an example of the use of antibodies labeled with alkaline phosphatase for detection of in situ hybridization, an infection with BNYVV virus in sugar beet is shown in Fig. 3C. Lectins labeled with an avidin-biotin fluorescein conjugate was used to visualize a-galactosyl groups on the surface of S. pombe in Fig. 3D. 

A collection of LPS structures, including some containing KDO residues of known linkage, has been assembled by Nikaido.72 Noticeable among these is the R-2-type core in Escherichia coli 0-100 studied by Hammerling and coworkers.73 The LPS from this strain contains a KDO residue that is substituted by a galactosyl group on 0-7 or 0-8. 

VIII), but the relevant reactions are more interesting when they constitute an integral part of a galactosylation cycle, and they will be described in Section...
