Liquid Chromatography with Electrospray Ionization and Tandem Mass Spectrometry Applied in the Quantitative Analysis of Chitin-Derived Glucosamine for a Rapid Estimation of Fungal Biomass in Soil.

International journal of analytical chemistry

Olofsson MA, Bylund D.
PMID: 26977151
Int J Anal Chem. 2016;2016:9269357. doi: 10.1155/2016/9269357. Epub 2016 Feb 09.

This method employs liquid chromatography-tandem mass spectrometry to rapidly quantify chitin-derived glucosamine for estimating fungal biomass. Analyte retention was achieved using hydrophilic interaction liquid chromatography, with a zwitter-ionic stationary phase (ZIC-HILIC), and isocratic elution using 60% 5 mM ammonium...

Multi-organ failure in response to uncontrolled microbial infection is characterized by low blood pressure accompanied by a systemic over-inflammation state, caused by massive pro-inflammatory cytokines release and liver damage. Recently, the integrated stress response (ISR), characterized by eukaryotic translation...

Isolation and characterization of glycoprotein lectins from the bark of three species of elder, Sambucus ebulus, S. nigra and S. racemosa.

PMID: 24233743
Planta. 1986 May;168(1):113-8. doi: 10.1007/BF00407017.

Lectins have been isolated from the bark of three members of the family Caprifoliaceae, Sambucus nigra (elder), S. racemosa (red-berried elder) and S. ebulus (dwarf elder), by affinity chromatography on fetuin-agarose, ion-exchange and gel-filtration chromatography. They are all glycoproteins...

Pharm Biol. 2013 Dec 13; doi: 10.3109/13880209.2013.846915. Epub 2013 Dec 13.

Abstract Context: Ulva lactuca Linnaeus (Chlorophyceae), a commonly distributed seaweed, is rich in polysaccharide but has not been studied extensively. Objective: The present study investigated the effects of crude fraction of Ulva lactuca polysaccharide (ULP) on d-galactosamine (d-Gal)-induced DNA...

Affinity chromatography of a lectin from Robinia pseudoacacia L. and demonstration of lectins in sieve-tube sap from other tree species.

Planta. 1979 Jan;144(4):367-71. doi: 10.1007/BF00391580.

A carbohydrate-binding protein in the sievetube sap of Robinia pseudoacacia L. was isolated by affinity chromatography on D-galactosamine coupled to CH-Sepharose 4B. The yield of the purified protein was 41,3 μg/ml of sieve-tube sap or 5,7% of the total...

Structural Elucidation of the O-Antigen Polysaccharide from Escherichia coli O181.

ChemistryOpen. 2015 Feb;4(1):47-55. doi: 10.1002/open.201402068. Epub 2014 Dec 01.

Shiga-toxin-producing Escherichia coli (STEC) is an important pathogen associated to food-borne infection in humans; strains of E. coli O181, isolated from human cases of diarrhea, have been classified as belonging to this pathotype. Herein, the structure of the O-antigen...

Different locations of carbohydrate-containing sites in the surface membrane of normal and transformed mammalian cells.

PMID: 24174197
J Membr Biol. 1970 Dec;3(1):267-79. doi: 10.1007/BF01868019.

A soybean agglutinin was found to agglutinate mouse, rat and human cell lines transformed by viral carcinogens, but not hamster cells transformed by viral or non-viral carcinogens. Normal cells from which the transformed cells were derived were not agglutinated...

Isolation and partial characterization of rainbow trout (Oncorhynchus mykiss) gill mucin.

PMID: 24202969
Fish Physiol Biochem. 1994 Jan;12(5):387-98. doi: 10.1007/BF00004303.

Gill mucin from rainbow trout was isolated utilizing two rounds of cesium chloride density ultracentrifugation followed by gel filtration on Sepharose CL-2B. Neither density ultracentrifugation nor gel filtration alone was sufficient for purification of the mucin. Isolated gill mucin...

When rats given D-galactosamine are then treated with the glucogenic amino acid alanine, their alanine aminotransferase (ALT) activity, total bilirubin level, and survival rate improve compared with when other amino acids are used. Here, we report a preliminary study...

Cell walls of pseudomonas species sensitive to ethylenediaminetetraacetic Acid.

Soybean (Glycine max L.) seeds contain a galactose-binding protein which displays two activities: (a) an alpha-galactosidase activity and (b) a hemagglutinin activity. The alpha-galactosidase-hemagglutinin was purified to homogeneity by conventional protein purification procedures and also by affinity chromatography. This...
