Comprehensive Amino Acid Analysis Services

Amino acids are the fundamental building blocks of life. Knowing exactly which ones are present—and in what amounts—provides a foundational understanding of your protein’s identity, purity, and composition. Whether you’re quantifying a therapeutic antibody, diagnosing a metabolic disorder from a plasma sample, or verifying a synthetic peptide, amino acid analysis delivers the critical, quantitative data you need for confident decision-making.

Our services go beyond a simple report. We provide a partnership with a GLP/GMP-certified amino acid analysis laboratory in India, offering global standards of quality and compliance at a competitive value. We help you unlock the compositional story of your samples, from basic research to regulatory submission.

Our Core Analytical Services

Qualitative Analysis of Amino Acids


This service answers the question: “What amino acids are present in my sample?” It is the first step in characterizing an unknown protein or verifying the composition of a recombinant product.

  • Ideal For: Identifying the amino acid composition in proteins and peptides, supporting structural research, and nutritional analysis.
  • Key Advantage: Provides a complete profile of the constituent amino acids, confirming the basic building blocks of your molecule.
  • Application: Essential for initial amino acid sequence analysis and verifying the composition of recombinant proteins.

Plasma Amino Acid Analysis


The amino acid profile in blood plasma is a powerful indicator of health and disease. Abnormal levels can signal metabolic disorders, nutritional deficiencies, and other clinical conditions.

  • Ideal For: Supporting clinical diagnostics, nutritional studies, and metabolic research.
  • Key Advantage: High-sensitivity quantification of a wide panel of amino acids from small sample volumes, providing critical data for healthcare professionals and researchers.
  • Application: Screening for inborn errors of metabolism, monitoring nutritional status, and clinical research studies.

Amino Acid Sequence Analysis Support


While not direct sequencing like Edman degradation, precise amino acid analysis is a critical supporting technique for sequence verification. By comparing the experimental amino acid composition to the theoretical composition derived from the DNA sequence, we can confirm protein identity and purity.

  • Ideal For: Confirming the identity of recombinant proteins, biosimilars, and synthetic peptides as part of a comprehensive characterization package.
  • Key Advantage: Provides orthogonal verification of protein structure, detecting major sequence errors or contaminating proteins.
  • Application: A required test for the biopharmaceutical protein characterization of therapeutics and biosimilars for regulatory submissions.

Applications of Amino Acid Analysis

The versatility of amino acid analysis makes it indispensable in numerous fields:

Qualitative Analysis of Amino Acids


Understanding the composition of a protein or peptide is the first step in characterization. This service is fundamental for confirming identity in research and development phases.

Plasma Amino Acid Analysis


As a key tool in metabolic screening, this analysis helps diagnose conditions like PKU, maple syrup urine disease, and other disorders by identifying characteristic imbalances in amino acid concentrations.

Supporting Amino Acid Sequence Analysis


For recombinant proteins, comparing the experimentally determined amino acid composition to the theoretical composition provides powerful, orthogonal confirmation of the amino acid sequence and protein identity.

Amino Acid Analysis of Proteins for Biopharmaceuticals


This is a critical test for quantifying protein concentration (using the absolute amino acid content) and verifying purity for batch release and stability studies of therapeutic proteins.

Case Study: Enabling Early Detection of a Metabolic Disorder through Plasma Analysis

The Challenge: A clinical research institute in India needed a highly reliable and sensitive method to screen patient plasma samples for subtle amino acid imbalances indicative of early-stage metabolic disorders, where traditional methods lacked sufficient precision.

Our Solution: We deployed our validated plasma amino acid analysis service using high-resolution LC-MS/MS. The method was optimized to accurately quantify over 30 different amino acids from a small volume of plasma with high precision and a rapid turnaround time.

The Outcome: The data we provided revealed a distinct aberrant profile in a subset of patients, correlating with a specific metabolic disorder with 98% accuracy compared to follow-up genetic testing. This allowed for early intervention and provided the institute with a robust dataset for their research publications.

FAQ About Amino Acid Analysis

Q1.What is amino acid analysis of proteins used for?


Amino acid analysis of proteins has two primary uses:

1) Quantitative: To determine the exact concentration of a protein by measuring the total yield of its constituent amino acids after hydrolysis. This is a fundamental method for protein quantitation.

2) Qualitative: To confirm the identity of a protein by verifying its amino acid composition matches the expected theoretical values.

Q2.How does plasma amino acid analysis support clinical research?


Plasma amino acid analysis is a key diagnostic tool. Many metabolic disorders disrupt the body’s ability to process specific amino acids, causing their levels in the blood to become abnormally high or low. By accurately measuring these levels, clinicians and researchers can diagnose diseases, monitor treatment efficacy, and conduct nutritional studies.

Q3.What techniques are used in amino acid sequence analysis support?


While our service supports sequence analysis, it is not direct sequencing. The process involves completely hydrolyzing the protein into its individual amino acids using acid. The resulting mixture is then separated and quantified using techniques like HPLC or LC-MS/MS. The experimental composition is compared to the composition predicted by the gene sequence to confirm identity.

Q4.Can amino acid analysis detect protein modifications?


It can indicate the presence of certain modifications indirectly. For example, if a modification alters the chemical stability of an amino acid during hydrolysis (like glycosylation), it may lead to an unexpected low recovery of that amino acid. However, for specific identification of modifications, targeted mass spectrometry methods are more appropriate.

Q5.Do you provide amino acid analysis services outside India?


Absolutely. We are a GLP/GMP-certified amino acid analysis laboratory in India that serves a global clientele. We have streamlined logistics for international sample submission, providing secure shipping guidelines and dedicated support to ensure a seamless experience for our clients worldwide.
