In addition to our reactive PromoFluor dyes and fluorescent Phycobiliproteins for biomolecule labeling, PromoKine also offers ready-to-use Protein and Antibody Labeling Kits. These innovative and user-friendly kits have been developed for convenient and highly efficient fluorescent and non-fluorescent labeling of your specific antibody or target protein of interest either with our superior PromoFluor dyes or with other common fluorophores and biomarkers such as fluorescein (FITC), R-phycoerythrin, and allophycocyanin as well as biotin, peroxidase or alkaline phosphatase (AP).

The PromoFluor Protein & Antibody Labeling Kits contain the respective PromoFluor NHS ester of choice as well as all the other components required for a convenient and efficient labeling of biomolecules. All molecules containing a primary amino group, like peptides/proteins or 5'-aminomodified DNA oligomers and cDNA containing aminoallyl-dU-units can be easily labeled.

In addition, PromoKine is provides protein labeling kits with common fluorophores such as fluorescein (FITC) or the strongly fluorescing phycobiliproteins R-phycoerythrin and allophycocyanin as well as kits for labeling proteins and antibodies with biotin, alkaline phosphatase or peroxidase.
These kits are available either with NH₂ reactive fluorophores containing an activated ester group, which easily allows to make a covalent bond with an amino group of a target molecule, or with SH-reactive fluorophores containing a maleimide group which allows to make a covalent bond with a sulfhydryl (thiol) group of a target molecule without any activation process. These kits contain all necessary reagents for fast, convenient and highly efficient fluorescence labeling as well as filtration tubes for purifying and concentrating the labeled proteins and antibodies.The Biotin PCR Labeling Kits contain all reagents required for convenient PCR labeling providing a highly efficient, rapid labeling technology.
