Descrição geral
The glycine standard is produced under stringent conditions and measured with the highest possible precision.
Aplicação
It can be used as an analytical standard to:
- Evaluate Kjeldahl′s procedure to determine total protein content of reference standards used in clinical laboratories.
- Analyze beer and wine for their protein and total usable nitrogen using a microwell ninhydrin assay.
- Compare Kjeldahl and Dumas methods for routine analysis of dairy products in an interlaboratory study.
- Simultaneously determine total phosphorus and total Kjeldahl nitrogen in surface water samples.
- Quantitatively determine nitrate in surface waters using Valdetrama method.
- Measure low level Kjeldahl nitrogen using an AutoAnalyzer.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The clinical associations of glycine receptor antibodies have not yet been described fully. We identified prospectively 52 antibody-positive patients and collated their clinical features, investigations and immunotherapy responses. Serum glycine receptor antibody endpoint titres ranged from 1:20 to 1:60 000.

Nuclear pore complexes (NPCs) mediate cargo traffic between the nucleus and the cytoplasm of eukaryotic cells. Nuclear transport receptors (NTRs) carry cargos through NPCs by transiently binding to phenylalanine-glycine (FG) repeats on intrinsically disordered polypeptides decorating the NPCs.
