HPLC analysis applications
HPLC is suitable for a wide array of compounds and is routinely used to partition or purify peptides or proteins due to its high resolving power, robustness and extreme reproducibility.

Mass spectrometry analysis service
Mass spectrometry analysis detects and quantifies known and unknown materials, mixtures and chemical structures of different molecules to provide precise, quantitative analysis and detection down to ultra-trace levels.
Measuring phenylalanine content in food, drink and medicinal products
Our method of post-column detection allows us accurately quantify very low levels of phenylalanine in food, drinks and medicinal products for those requiring a low protein diet.
Method considerations for the analysis of amino acids
We use the most robust amino acid analysis method available: separation of a mixture of amino acids using ion exchange chromatography followed by post-column photometric detection.
Analysis of Tryptophan, Cysteine and Cystine amino acids
For the analysis of these specific amino acids in samples, AltaBioscience uses different methods that enable us to quantify them accurately.
Influenza virus peptides
Although there are ways to combat influenza viruses, they have evolved to mutate frequently in order to evade the host’s immune system.
Case study: Method development for the amino acid analysis of a complex material.
This case study highlights the work performed by our scientists to overcome the challenges in the development of this adapted amino acid analysis method.
Amino acid analysis methods review: Post column detection method compared to Kjeldahl and Dumas methods
We discuss three methods widely used for the acquisition of protein content in food products. Methods are briefly explained and the advantages and disadvantages of each explored.
Protein and peptide tags
Protein and peptide (epitope) tag sequences are attached to proteins to facilitate easy detection and purification of expressed proteins.
Total and free amino acid analysis
Total amino acids analysis determines the amino acids which are bound in proteins as well as those amino acids that may be present as individual unbound units.
