1 Hour Lunch Break

This hands-on three-day Cell Line Authentication and Reproducibility workshop is designed for scientists involved in laboratory research using cell cultures and or antibodies.


Cell Line Authentication • Cross Contamination • Mycoplasma Detection • Antibody Characterization/Validation

Identified as significant contributors to the current quality-control challenges in cell culture-based research*, this workshop will address methods and practices to ensure reproducibility and good cell culture practice (GCCP). Benefits also will extend to satisfy the new NIH grant requirements as well as those of publication outlets.

*NIH Workshop on Reproducibility in Cell Culture Studies, September 28-29, 2015

Cross Contamination/Misidentification: Consequences Detection and Prevention; GCCP

Cell Line Authentication: Authentication of Human Cell Lines by STR Profiling Including Data Analysis; NIST STR Standards; Authentication of Non-Human Cell Lines: Isozyme Analysis; CO1 Multiplex Assays, STR Profiling

Mycoplasma Contamination: Severity, Causes, Effects and Prevention; Testing Regimens: Efficacy of Various Mycoplasma Tests; FDA Gold Standard, WHO Protocol, Culture test, DNA stain (Hoechst 33258), Enzymatic Assay and PCR Tests; Rescue of Valuable Contaminated Cell Lines; Alterations in Gene Expression; Detection of Transcriptisome Contamination Studies (RNA-seq); How to Detect Contaminated Transcript files using NGS

Antibodies: Overview: Specific Issues Associated with the Use of Antibodies Including Antibody Origins (Mabs vs. Polyclonal Abs), Cross-Reactivity, Genetic Drift of Hybridomas; Care and Maintenance of Hybridomas; Consequences of Using “Bad” Antibodies; Purity of Antibody Preparations: Antibody Contamination, Standard Methods for Detection (SDS-PAGE, HPLC), in vivo vs. in vitro; Purification of Antibodies Bias: Changing Isotype Distribution/Profile of Polyclonal Antibodies Depending on Purification Method; Antibody Validation: Addressing the Difference Between Validation and Batch-to-Batch Variations; Isotype Confirmation: ELISA Based Checks for Contamination with Other Ab; Western Blot: Advantages and Limitations; Immunoprecipitation followed by SDS-PAGE: Overcoming WB-limitation of Many Mabs (how does IP work, how to “adapt” it to use of mabs); Flow Cytometry; Blocking studies: Using Competing Antibodies, Blocking Peptides/Proteins to Verify Specificity

Jamie Almeida
Jamie Almeida is a research biologist working in the Bioassay Methods Group at NIST. Some of her past contributions include: 1) stability studies for B. anthracis Sterne spores, 2) development of a rapid bioassay test for ricin using a GFP expressing cell line, and 3) decontamination of various biothreat agents in water systems in the presence and absence of pipe biofilms. Jamie has worked closely with the DNA forensics group at NIST since 2010 learning to separate short tandem repeat alleles using capillary electrophoresis and optimizing multiplex PCR assays. Using this knowledge, she has focused her efforts on the identification of non-human cell lines, specifically monkey, mouse, hamster, and rat. She is currently running the Mouse Cell Line Authentication Consortium, a collaboration between NIST, ATCC, and 11 other labs to validate 19 mouse STR markers to be used for commercial services for identity determination of mouse cell lines.
W.Leitner InstructorWolfgang Leitner, Ph.D.
Dr. Wolfgang Leitner the Chief of the Innate Immunity Section at the National Institute of Allergy and Infectious Diseases (NIH). He has been teaching flow cytometry for 25 years. He previously worked at the National Cancer Institute where he developed various flow cytometric protocols for the evaluation of experimental cancer vaccines.
Rigor and Reproducibility InstructorBecky Steffen
Becky Steffen is a research biologist working for the Applied Genetics Group at NIST. Her work primarily focuses on short tandem repeat (STR) multiplex development; the characterization of additional miniSTR loci; low template DNA analysis; concordance evaluations with new commercial STR kits and capillary electrophoresis (CE) instruments; next generation sequencing (NGS), and Standard Reference Material (SRM) development.
Elke Bergmann-Leitner, Ph.D.
Dr. Elke Bergmann-Leitner is the Chief of the Flow Cytometry Center (Malaria Vaccine Branch) at the Walter Reed Army Institute of Research in Silver Spring, MD. She is an adjunct Research Associate Professor of Medicine at the Uniformed Services University of Health Sciences and has been teaching flow cytometry for 25 years. Currently, her main research focus is the development of readout methods capable of identifying immune correlates of protection against infectious diseases.

In Memoriam:

Roland Mario Nardone, PhD

Professor of Emeritus Catholic University of America

March 30, 1928 — June 20, 2018

Dr. Nardone graduated from high school when he was 15, was the first in his family to go to college, and he got his Ph.D. at the age of 23. He had an enormous passion for teaching, starting his research and teaching career at St. Francis College and St. Louis University, then as a Professor of Biology at Catholic University of America (CUA) for over 50 years.  His focus of research covered many areas, from In Vitro toxicology model systems to the effect of microwave radiation on gene expression.  His passion for teaching eventually led to the development of 2 organizations that provided hands-on training for research scientists, the “Center for Advanced Training in Cell and Molecular Biology” at CUA and “Bio-Trac Training Programs” of which is still going strong today, having provided training to over 17,000 scientists.

Still professionally productive throughout his remaining days, Dr. Nardone focused on the importance of reproducible scientific results, raising awareness to the scientific community regarding the need for cell line authentication and mycoplasma detection as well as the effects of cellular cross contamination.  At a workshop on Reproducibility at the NIH on September 30, 2015, Dr. Nardone was introduced by Dr. Larry Tabak, Principal Deputy Director, National Institutes of Health, as follows: “Dr. Roland Nardone, a pioneer who sounded the alarm in 2005 …” On behalf of the entire community, thank you.” On January 25, 2016 a zero tolerance policy for NIH grants became effective.
