An analytical quality by design (aQbD) approach for a L-asparaginase activity method.

J. Pharm. Biomed. Anal. 117 , 232-9, (2015)

L-asparaginase is an effective anti-tumor agent for acute lymphoblastic leukemia. This work presents the development of an activity determination of L-ASNase preparations for pharmaceutical quality control purposes, in accordance with analytical Quality by De...

Influence of Free Amino Acids, Oligopeptides, and Polypeptides on the Formation of Pyrazines in Maillard Model Systems.

J. Agric. Food Chem. 63 , 5364-72, (2015)

Pyrazines are specific Maillard reaction compounds known to contribute to the unique aroma of many products. Most studies concerning the generation of pyrazines in the Maillard reaction have focused on amino acids, while little information is available on the...

Simultaneous determination of acrylamide, asparagine and glucose in food using short chain methyl imidazolium ionic liquid based ultrasonic assisted extraction coupled with analyte focusing by ionic liquid micelle collapse capillary electrophoresis.

Food Chem. 188 , 551-8, (2015)

Acrylamide (AA) is a known lethal neurotoxin and carcinogen. AA is formed in foods during the browning process by the Maillard reaction of glucose (GL) with asparagine (AS). For the first time, the simultaneous online preconcentration and separation of AA, AS...

Metabolic effects on recombinant interferon-gamma glycosylation in continuous culture of Chinese hamster ovary cells.

Biotechnol. Bioeng. 62 , 336-347, (1999)

Asparagine linked (N-linked) glycosylation is an important modification of recombinant proteins, because the attached oligosaccharide chains can significantly alter protein properties. Potential glycosylation sites are not always occupied with oligosaccharide...

Purification and characterization of recombinant human lysosomal alpha-mannosidase.

Mol. Genet. Metab. 73 , 18-29, (2001)

Lysosomal alpha-mannosidase (EC 3.2.1.24) is required in the degradation of the asparagine-linked carbohydrates of glycoproteins. Deficiency of this enzyme leads to the lysosomal storage disorder alpha-mannosidosis. As an initial step toward enzyme replacemen...

Synthesis, purification and characterization of recombinant glycosylated human prolactin (G-hPRL) secreted by cycloheximide-treated CHO cells.

J. Biotechnol. 145 , 334-340, (2010)

Human prolactin (hPRL) is a 199 aminoacid protein hormone with a wide spectrum of biological activities which is best known for its stimulation of lactation and development of mammary gland. This protein contains only one potential asparagine-linked glycosyla...
