Our Leadership

The owners have combined experience of 20+ years in flow cytometry and 15+ years working in a Good Laboratory Practice (GLP) environment.

Lynette Brown, MS, CHT

President and Flow Cytometry Specialist

Lynette has 15+ years professional experience in flow cytometry both in the clinical and research settings. Lynette has experience with many specimen types including whole blood and tissue from rodents, dogs, non-human primates and humans. She has developed and validated numerous assays for surface and intracellular markers and NK cell function that have been used on more than 50 GLP studies.

Lynette is in charge of the day to day operation of the laboratory which includes training, instrument maintenance and validation, specimen handling, sample acquisition and data analysis.

Jennifer J. Stewart, PhD

Vice President and Laboratory Director

Dr. Stewart has over 20 years professional experience and is responsible for overseeing internal and client sponsored research, preclinical or clinical drug studies using human specimens, non-human primate, dog or rodent models. She scientifically reviews the documentation, analyzes and reports flow cytometry data and communicates directly with Study Directors, Study Monitors and Clients.

Jennifer is currently serving as the Co-chair for the AAPS Flow Cytometry Action Programming Committee and has served as a guest editor for Cytometry Part B: Clinical Cytometry and as a scientific reviewer for the Journal of Immunological Methods and Clinical and Vaccine Immunology.

We are a high throughput and high capacity facility running multiple flow cytometers, and up to 10 colors daily.

Specialized Service

By focusing on flow cytometry services, FCSL is able to ensure that there is no dilution of the scientific and managerial focus because of unrelated upstream and downstream functions.

We utilize Becton Dickinson flow cytometers. Currently our facility houses a BD FACSCantoA cytometer with two scatter parameters and up to 6 fluorescent channels,  three BD FACSCantoII cytometers with two scatter parameters and up to 8 fluorescent channels, and two BD FACSCanto cytometers with two scatter parameters and up to 10 fluorescent channels. We also have two Guava PCAs which perform all of our cell count and viability assessments.

We are proficient in processing a multitude of specimen types including whole blood, tissue, frozen PBMCs and tumors for pre-clinical model systems and human clinical trials.

Specimen Shipping

FCSL operates as an outsourcing CRO in which specimens are shipped to us for analysis. This provides our clients more flexibility in choosing a laboratory and can reduce overload of their internal resources.

Since we rely on shipped specimens, we conduct rigorous qualification and validation of our assays to ensure specimen stability is well understood. We will work closely with you to determine appropriate sample preparation and shipping requirements for a particular assay.
