Scientific Description

L-Glutamic acid _-p-nitroanilide (Glu-pNA) is a high-purity synthetic compound used extensively in biochemical and enzymatic assays. Supplied as a lyophilized powder under catalog number MDP0097, this molecule features a molecular formula of C₁₁H₁₃N₃O₅ and a molecular mass of 267.24 g/mol. Its structure includes a p-nitroanilide group, making it a valuable chromogenic substrate for glutamyl-specific enzymes.

Researchers utilize Glu-pNA in kinetic studies, enzyme activity profiling, and substrate specificity assays. Its chromogenic properties allow for spectrophotometric detection, enabling precise quantitation of enzymatic reactions. The compound’s stability and solubility in aqueous buffers make it ideal for high-throughput screening and standard curve generation in enzyme-linked assays.

Storage at -20 °C ensures long-term integrity and reproducibility across experimental workflows. In practice, Glu-pNA is reconstituted in buffered solutions and used in microplate formats or cuvette-based spectrophotometry. Its defined chemical profile supports SOP compliance and LIMS traceability, making it a reliable tool for academic and industrial research settings.

Why researchers choose this product:

  • High-purity substrate for glutamyl enzyme assays
  • Chromogenic detection via p-nitroanilide group enables precise quantitation
  • Stable powder format supports long-term storage and reproducible results
  • Compatible with spectrophotometric and microplate-based workflows
  • Ideal for enzyme kinetics, substrate profiling, and biochemical screening

WARNING: For in vitro Research Use Only. NOT for use on humans or animals.
