Thermo Scientific™ Pierce TNBSA is a 5% solution of trinitrobenzene sulfonic acid in methanol that reacts with primary amines (peptides or amino acids) to yield a soluble colored product, a property useful for various assay methods.
Highlights:
- Couples with primary amines, sulfhydryls and hydrazides in aqueous solution at pH 8, without undesirable side reactions
- Excellent for solution or solid phase analysis
- Suitable for qualitative and quantitative estimation of biomolecules
- λmax = 335nm
- Reacts readily with primary amino groups of amino acids in aqueous format at pH 8 to form yellow adducts
- No colored derivatives are formed with secondary amino acids proline and hydroxyproline
- Colored derivatives are monitored at 345nm and have extinction coefficients in range of 1-1.5 x 104
