In addition to the standard dyes, specifically designed PromoFluor LSS dyes offer an exceptional large Stokes shift, which makes them ideally suited for multicolor labelling and flow cytometry applications.
PromoFluor NHS-Esters (N-hydroxysuccinimidyl-esters) are intended for covalently labelling biomolecules containing a primary amino group (all peptides/proteins contain at least one amino group at the N-terminus). Moreover, amino groups can also be incorporated in other biomolecules without changing their activity or functionality. The most common examples are 5’-amino-modified DNA oligomers and cDNA containing aminoallyl-dU.
