SurModics Introduces New In Vitro Diagnostics Product -
SurModics(R) Assay Diluent (Protein-Free)

EDEN PRAIRIE, Minn., Jul 26, 2011 (BUSINESS WIRE) --

SurModics, Inc. (Nasdaq: SRDX), a leading provider of drug delivery and surface modification technologies to the healthcare industry, will introduce its SurModics(R) Assay Diluent (Protein-Free) product at the American Association for Clinical Chemistry (AACC) - Clinical Lab Expo, July 26-28, 2011 in Atlanta, GA (booth #1302).

The SurModics Assay Diluent is a proprietary, protein-free, buffer formulation that reduces matrix interference (false positives) in patient samples due to heterophilic antibodies, such as Human Anti-Mouse Antibody (HAMA) and Rheumatoid Factor (RF). Assay diluents are used in Enzyme-Linked Immunosorbent Assays (ELISA) to equalize differences between the patient samples and standards. ELISA, a common immunoassay format, is typically used as a diagnostic tool to detect the presence or absence of a disease.

Features of the SurModics Assay Diluent

  • Reduces matrix interferences by blocking non-specific binding
  • Improves signal to noise ratio
  • Provides a protein-free alternative to eliminate BSA-related issues
  • Performs as a sample diluent, standard curve diluent, and antibody diluent

"This addition to SurModics' line of immunoassay reagents further demonstrates our dedication to providing innovative products to the in vitro diagnostics industry," said Gary Maharaj, president and chief executive officer of SurModics. "SurModics is excited to support its diagnostic customers with new product introductions that meet their needs."
