Enzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits.

BioAssay Works offers extensive experience to conjugate specified ligands (conjugating soluble proteins, haptens, hydrophobic proteins, viral and bacterial proteins) to BioAssay Works novel gold sols to speed assay research.
The Au/Ag particles have increased advantages in light or laser applications, when taking light scattering measurements. The BioAssay Works silver/gold nanoparticles and conjugates production process is unique, by eliminating the boiling step, and because of the concentrated gold, you do not have to dilute the sols prior to conjugation, nor do they have to be centrifuged to remove free antibody. The elimination of these two s…
