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.
Amino acid analysis method considerations
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.
Amino acid analysis: For accurate quantification of protein and amino acid content
Amino acid analysis is the most accurate way to determine the composition and quantity of protein in a sample.
Peptides for Raising Antibodies
In this article, we discuss methods for generating custom antibodies using peptide antigens including peptide antigen design considerations and options for generating antigenic peptides. In general, synthetic peptides are too small to elicit an immunogenic response.
