Molecular Microbiology


Ana Gradissimo

Founded in 2009, the Molecular Microbiology Facility (MMF), currently supported by the van den Brink Laboratory, is a comprehensive resource for microbiome research at Memorial Sloan Kettering Cancer Center (MSKCC), providing researchers with a cost-effective, high-throughput processing of biological microbiome samples.

The MMF manages a Fecal Biobank and stores and catalogues thousands of human stool samples from patients at MSKCC collected under protocols and clinical trials. The laboratory specializes in methodologies optimized to investigate the microbial composition of human or experimental mouse samples.

We provide services ranging from nucleic acid extraction to bacterial/fungal amplicon sequencing or metagenomics using Illumina platforms in collaboration with the Integrated Genomics Operation (IGO). The MMF supports investigators pursuing basic and clinical research interests in analyzing the microbiota of the small and large intestines, feces, saliva and oral mucosal surfaces, urogenital tract, and skin.

Investigators wishing to utilize our shared facility to bank research specimens or process samples should submit all requests through iLab or submit inquiries via email to Ana Gradissimo at [email protected] . External investigators can also use our iLab account for request submission.
