Peptide assay kit

Short amino acid chains or peptides play key roles in many biological functions.  Peptides from antigens are

responsible for immune responses.  Many biologically secreted and synthetic peptides have been used or

being developed as drugs in various therapeutic areas including treatment of infection, cancer, diabetes, and

cardiovascular diseases.  The MicroMolar Peptide Assay Kit (Catalog number PEP200) is designed for

concentration measurement of various peptides. The assay is based on increase of fluorescence at 535 nm

of the dye C57 in the presence of peptides.  The assay kit can be used for measurements peptide

concentrations in synthetic or biochemical reactions, pharmaceutical products and environmental water

samples.

The MicroMolar Peptide Assay Kit (catalog number PEP200) provides the reagent for measurement of 200

samples using 96-well plates.  Cuvettes may also be used for measurements. The assay sensitivity varies

from micromolar to millimolar concentrations depending on the nature of peptides.  The assay is compatible

with HEPES buffer, low concentrations of non-ionic detergent (<0.01%), MgCl2 (< 5 mM), CaCl2 (<5 mM),

EDTA (< 1 mM) and phosphate (< 1 mM). It is not compatible with thiol compounds such as DTT.
