LEXINGTON, Ky., Dec. 8, 2020 — Neogen today announced the development of two new TMB substrates that deliver excellent performance and expands our popular K-Blue® product line to meet the evolving needs of our valued customers.

  • Neogen’s new K-Blue Advanced Plus is a one-bottle, ready-to-use solution offering superior activity, low background, good lot-to-lot consistency and long-term stability, and compliance with the REACH Restricted Substrates List Annex XVII. K-Blue Advanced Plus contains no hazardous substances at or above published reporting levels, is ideal for assays requiring high activity.
  • Neogen’s new K-Blue Select offers the same benefits as K-Blue Advanced Plus, including the REACH Restricted Substrates List Annex XVII compliance, but offers a mid-level activity range.

“The development of K-Blue Advanced Plus and K-Blue Select demonstrates our ongoing commitment to providing high quality reagents to meet the changing and expanding requirements of our customers,” said Neogen’s Emilie Stanley. “We are very pleased to be able to offer these new substrates that deliver the exceptional performance that our customers have come to expect from K-Blue substrates, and yet are formulated to reduce even further any potential impacts on human health and the environment.”  

As an immunoassay manufacturer, Neogen recognizes that one TMB (3,3',5,5'-tetramethylbenzidine) microwell substrate formulation will not meet the specifications of all HRP-based (horseradish peroxidase) immunoassays. Therefore, Neogen offers multiple unique one-bottle TMB microwell colorimetric substrate formulations to meet specific requirements for different assay systems.

With over 30 years of experience developing and manufacturing ELISA test kits and substrates and reagents, Neogen provides the support and products for dependable and reliable results every time, including: an extensive line of research ELISA test kits, substrates and reagents for immunoassay applications, testing equipment packages, and experienced technical support.
