Laboratory for Molecular Typing (LMT)

All PFGE  submissions must arrive by December 8th in order to be reported before the holiday.
Since the university is closed during this time, there is no package receiving. Please plan your shipments accordingly.
We wish you a safe and happy holiday.

Welcome to the home page for the Cornell University Laboratory for Molecular Typing

The Laboratory for Molecular Typing (LMT) is a fee-for-service facility within the New York State College of Agriculture and Life Sciences at Cornell University. The LMT, established in 1996 by Professor Carl A. Batt is currently under the direction of Professor Martin Wiedmann.  While we follow PulseNet’s standard protocols, we are not a member of the Centers for Disease Control and Prevention (CDC) PulseNet system.

The lab offers a wide variety of technologies to identify and characterize microorganisms to the genus, species, and subspecies level. Services are strictly confidential. We do not submit isolates or patterns to the CDC.

Discounts are available for educational institutions and companies within New York State. Researchers within Cornell University should contact the lab regarding pricing options. 

Services and fees

Pulsed Field Gel Electrophoresis (PFGE) Typing  uses the Centers for Disease Control and Prevention (CDC) PulseNet Protocol and BioNumerics Analysis Software to produce high quality, reproducible genetic fingerprints for pathogenic organisms, but our numbering system is separate from CDC PulseNet’s. We can provide electronic files if you want to submit our results to the CDC for comparison.

If you are interested in having whole genome sequencing of bacterial isolates performed please contact Martin Wiedmann ( for details.

The LMT offers additional subtyping services for select food borne pathogens, including MLST.  Please contact Sherry Roof ( for more information. 

Fees:  All fees listed are cost per isolate.
