詳細

The glycine standard is produced under stringent conditions and measured with the highest possible precision.

アプリケーション

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.

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.
