Hi everybody!
I have a question: I need an amino acid standard mixture for quantification experiments on a GC!
We have a standard with 20 amino acids, but I would like to have one with more different amino acids - sigma sells one with about 30 compounds - does anybody know if there is a company selling a standard with more compounds?
Thanks for your help!
Hi Benedikt, there are a lot of companies that sell purified recombinant proteins. Many of these companies do AA analysis of their products as standard QC for purity.
what kind of amino acids you are expecting to be included in assay mixture? 20 aa belongs to proteinogenic group. There is a lot of non proteinogenic amino acid but the number of them exceeds 30 .... Do you mean some proteinogenic aa with transnational modifications? Such derivatives are quite expensive.
you can call me ...i can help you to get standard amino acids
or email me on [email protected] with details requirements.
My company can give you
