Enzo Biochem Unit Launches First-To-Market Survival Motor Neuron (SMN) Protein Immunoassay System. SMA Is Leading Geneticcause of Infant and Toddler Mortality

FARMINGDALE, NY and NEWYORK, NY (March 15, 2011) – Enzo Biochem, Inc. and the Spinal Muscular Atrophy(SMA) Foundation today announced that Enzo’s wholly owned subsidiary, Enzo LifeSciences Inc., has launchedaunique immunoassay (ELISA) system which can be used for the identification anddetection of Survival Motor Neuron (SMN) protein. The kit is the result of acollaborative agreement between Enzo and the SMA Foundation.for the developmentof reagents and assays for SMN protein. The availability of an effective SMNELISA could further enable and expedite drug discovery, development and therapyfor Spinal Muscular Atrophy, the leading genetic cause of mortality in infantsand toddlers.
SMA is a genetic,neuromuscular disease caused by progressive degeneration of nerve cells in thespinal cord that leads to muscular weakness and atrophy and increased risk forearly death due to respiratory failure.It is estimated that SMA affectsapproximately 1 in 6,000 to 1 in 10,000 live births worldwide. The disease islinked to a mutation in or deletion of the SMN1 gene, resulting in reducedlevels of SMN protein. An active area of therapeutics development has beenelevation of SMN protein levels.

“The SMN ELISA kitaddresses a critical gap in SMA research and is expected to significantlyaccelerate SMA therapeutics development. Development and distribution of thissystem could not happen without the successful collaboration with Enzo andcontributions from the SMA research community,” said Karen Chen, Ph.D., theChief Scientific Officer of the SMA Foundation.

The Enzo SMN ELISA Kitprovides a reliable and widely-accessible means for researchers to measure SMNprotein levels, and greatly simplifies and accelerates efficacy assessment ofpotential drugs in clinical trials that are designed to increase SMN proteinlevels.The assay has beenvalidated for use with human and mouse cell lysates and tissue homogenates, suchas peripheral blood mononuclear cell (PBMC) lysates, and will be marketedthrough Enzo’s worldwide sales and marketing group.

“During the assaydevelopment, the SMA Foundation facilitated the supply of assay kits toaffiliated researchers in theUSand abroad.This allowed us to validate the assay in-house while simultaneously receivingvaluable feedback about assay specifications, performance, and protocols fromscientists who will ultimately be using the kits in their studies,” said WaynePattonPh.D., Chief ScientificOfficer at Enzo Life Sciences. “Our custom assay development team continues towork with the SMA Foundation to expand the utility of the kit to includeadditional sample types and protocols relevant to SMA research programs andmodel systems, which should add further value to the assay in themarketplace.”
