The DELFIA Eu-N1 ITC chelate is optimized for the europium labeling of proteins and peptides for use in dissociation-enhanced time-resolved fluorometric assays. Isothiocyanate (ITC) activated chelates react primarily with free amine groups such as those at the N-terminus of protein or lysine residues.
Each kit contains 0.4 mg labeling reagent plus Eu-standard, DELFIA Enhancement Solution, Eu-stabilizer, purified BSA for increasing the stability of labeled proteins, an uncoated microtitration strip plate, DELFIA Assay Buffer and DELFIA Wash Concentrate. The kit contents are sufficient for a labeling of up to 1 mg of protein or antibody.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
