Glycopeptides molecular weights

The column was 25 cm long, 4.6 mm I.D. and packed with Partisil 10. It is seen that linear curves were obtained for three different solutes and two different moderators in n-heptane. Scott and Beesley [14] obtained retention data for the two enantiomers, (S) and (R) 4-benzyl-2-oxazolidinone. The column chosen was 25 cm long, 4.6 mm I.D. packed with 5 mm silica particles bonded with the stationary phase Vancomycin (Chirobiotic V provided by Advanced Separations Technology Inc., Whippany, New Jersey). This stationary phase is a macrocyclic glycopeptide Vancomycin that has a molecular weight of 1449.22, and an elemental composition of 54.69% carbon. 

Chemical-ionization, mass fragmentography was used for quantitative determination of variously linked monosaccharides in a study of the high-molecular-weight glycopeptide of erythrocytes.75 It appears...

Vancomycin is an antibiotic produced by Streptococcus orientalis and Amycolatopsis orientalis. With the single exception of flavobacterium, it is active only against gram-positive bacteria, particularly staphylococci. Vancomycin is a glycopeptide of molecular weight 1500. It is water soluble and quite stable.

The heat stability of glutaminase-asparaginase modified with glu-taraldehyde-activated glycopeptides was slightly greater than that of the native enzyme, as was its susceptibility to trypsin.108 This modification decreased the pi by several pH units, and altered the association behavior the glycosylated enzyme had a much wider distribution of molecular weights as determined by sedimentation equilibrium. 

Thereafter, to remove suspected high-molecular-weight polysaccharide contaminants, a modified filtration procedure was developed. This particular procedure involved first passing the original 80%-ethanol extract of the microbubble glycopeptide surfactant through a 5,000-dalton cut-off molecular filter (Nucle-... 

Calculation is based on a molecular weight of approximately 5,200 daltons for untreated microbubble glycopeptide surfactant, as determined in Table 4.3. 

This form of electrophoresis is not directly applicable to molecular weight determinations of glycoproteins. Glycoproteins and glycopeptides containing more than 10% carbohydrate behave...
