Histone peptides and microarrays
AltaBioscience stock a selection of individual histone peptides and 5 different histone peptide sets. The peptide sequences are derived from human histones H2A, H2B, H3 and H4 and include a range of modified amino acids.
DNA Peptide Conjugates
At AltaBioscience, we offer different options for conjugation either at the 3’ end of the oligo or at the 5’ prime end, depending on your requirements. In addition, the linkage between the DNA-peptide can be either a stable covalent bond or a reducible disulphide bridge as needed for your application.
Histone Peptides
AltaBioscience has provided custom synthesis of histone peptides from human H2a, H2b, H3 and H4 regions for many years, having collaborated with the original scientist who developed the idea for histone assays.
Peptide antigens for antibody generation
Suitable for both monoclonal antibody production and polyclonal antibody production, our peptide synthesis experts can assist with peptide antigen design using our epitope design software thereby suggesting antigenic peptide regions likely to provide the best immune response.
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.
