 Lecture 1: Recent Advances in CRISPR/Cas9 Genome Editing Technology: From eSpCas9
 to Whole-Genome Screening

Time: 2:00 PM – 2:50 PM


Genome editing has enabled the investigation of gene function and target identification, and is helping researchers develop potential therapies against a wide range of diseases. MilliporeSigma has been an industry leader in genome editing technology since 2002 when it introduced the TargeTron system for gene editing in prokaryotes. Five years later, it became the first company to commercialize eukaryotic genome editing technology in the form of Zinc Finger Nucleases (ZFNs). The company was at the forefront of the CRISPR revolution in 2012, and continues to develop cutting-edge genome and epigenome editing tools with ever greater target specificity and robust cutting activity.

After an introduction to CRISPR/Cas9 technology, this presentation will highlight the latest developments in the field of genome editing. We will discuss strategies to enhance homology-directed repair (HDR) to facilitate gene insertion or swap, including Cas9-Geminin. We will describe enhanced-specificity Cas9 (eSpCas9), which is a rationally engineered version of wild-type SpCas9 with significantly fewer off-target effects. We also will illustrate the proxy CRISPR targeting strategy, which makes CRISPR gene editing more efficient, flexible, and specific. We will explain epigenetic applications of CRISPR technology, including dCas9-p300 and CRISPR-SAM activators. We also will highlight pooled and arrayed CRISPR libraries, such as the widely-acclaimed Sanger LentiCRISPR array, which allows whole-genome or gene family screening. The presentation will end with a brief overview of other emerging technologies available from MilliporeSigma.

Topics that will be discussed include:

  1. CRISPR Background & Mechanism
  2. Recent CRISPR Innovations
       a. HDR enhancement
       b. SygRNA & eSpCas9
       c. Proxy CRISPR
  3. Exciting CRISPR Applications
       a. Epigenetic activators
       b. Whole genome lentiviral arrays & pools
  4. Emerging Technologies from MilliporeSigma

 Lecture 2: What Have I Done?!: How to Determine the Effects of Gene Editing on
 Cellular Phenotype

Time: 3:00 PM – 3:50 PM


The use of innovative gene editing technologies, such as CRISPR/Cas9, continues to become more common in a variety of research areas, including oncology and infectious diseases. Manipulating characteristics of genomic DNA or RNA expression levels can have profound effects on cellular protein levels, and, thus, viability and overall phenotype of the targeted cells. Therefore, the downstream effects of any genetic manipulation must be thoroughly assessed and understood in order for researchers to accurately interpret resultant experimental data.  In this presentation, we will discuss how protein-based analysis using flow cytometry and quantitative, multiplexing protein concentration measurements can be easily integrated into any study to achieve phenotyping goals. We will highlight the combined use of CRISPR/Cas9, Guava flow cytometers, and Milliplex protein multiplexing assays from recently published literature and will be available to discuss specific study-design questions.

Topics that will be discussed include:

  1. Overview of Guava flow cytometry technology and uses for analyzing cell health
  2. Overview of Luminex xMAP® technology and Milliplex®MAP multiplexing assay panels
