Michael S. Fernandopulle, Ryan Prestil, Christopher Grunseich, Chao Wang, Li Gan, Michael E. Ward 10.17504/protocols.io.54rg8v6 Neurodegeneration Method Development Community Accurate modeling of human neuronal cell biology has been a long-standing challenge. However, methods to differentiate human induced pluripotent stem cells (iPSCs) to neurons have recently provided experimentally tractable cell models. Numerous methods that use small molecules to direct iPSCs into neuronal lineages have arisen in recent years. Unfortunately, these methods entail numerous challenges, including poor efficiency, variable cell type heterogeneity, and lengthy, expensive differentiation procedures. We recently developed a new method to generate stable transgenic lines of human iPSCs with doxycycline-inducible transcription factors at safe-harbor loci. Using a simple two-step protocol, these lines can be inducibly differentiated into either cortical (i3Neurons) or lower motor neurons (i3LMN) in a rapid, efficient, and scalable manner (Wang et al., 2017). In this manuscript, we describe a set of protocols to assist investigators in the culture and genetic engineering of iPSC lines to enable transcription factor-mediated differentiation of iPSCs into i3Neurons or i3LMNs, and we present neuronal culture conditions for various experimental applications. © 2018 by John Wiley & Sons, Inc.

Integrated Islet Distribution Program 10.17504/protocols.io.bfsfjnbn Integrated Islet Distribution Program, Integrated Islet Distribution Program and Human Islet Phenotyping Program This SOP defines a standardized method for packaging and cold shipping of research quality islets to approved investigators of human isolated islet preparations, for use in the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored research in the Integrated Islet Distribution Program (IIDP). This protocol is written to assist the participating islet isolation centers and investigators who are part of this program.Note: This SOP was developed based on the Prodo Labs, Inc. shipping protocol and results from preliminary studies conducted by the IIDP and commissioned by the original IIDP Project Officer, and External Evaluation Committee (EEC).It was commissioned due to problems with acquiring the supplies that were used in IIDP SOP: SHP-001 and with the hope that this method is a better means for transportation of IIDP islets. Preliminary studies proved the islets by the Prodo Labs’ method were statistically as good as the original IIDP method, it was preferred by the test researchers, and was much more cost effective for the IIDP. This new method may be modified as future methods are tested and approved by the IIDP Team, Project Scientist (PS), the Program Official (PO), and EEC.

Sam Li 10.17504/protocols.io.7bihike BioLegend BioLegend MojoSort™ nanobeads work in commonly used separation columns, based on our internal research as well as validation by external testing by academic labs. This simple protocol consists of following the MojoSort™ protocol to label the cells with pre-diluted MojoSort™ reagents and using the columns as indicated by the manufacturer.Note: Due to the properties of our beads, it may be possible to use far fewer beads and less antibody cocktail that with other commercial suppliers. We recommend a titration to find the best dilution factor. However, as a general rule, dilutions ranging from 1:2 to 1:10 for the antibody cocktail can be used. Dilutions ranging from 1:5 to 1:20 for the Streptavidin Nanobeads can be used. Please contact BioLegend Technical Service ([email protected]) if further assistance is needed.

De-MetaST-BLAST, written in C++, is a script that can validate degenerate primers by performing in silico PCR amplification of the primers against metagenomic and metatranscriptomic databases (e.g. CAMERA; MG-RAST). The output is a list of in-silco PCR amplicons that are then blasted against GenBank to determine the most homologous sequence to the amplicon. Modified from Gulvik, C. A., Effler, T. C., Wilhelm, S.

Steps to Create FASTQ of CCS Overlapping Genomic SSR - CCS ROI
 
Resource Report

Gregory Harhay 10.17504/protocols.io.9i7h4hn The virulence and pathogenicity of bacterial pathogens are related to their adaptability to changing environments. One process enabling adaptation is based on minor changes in genome sequence, as small as a few base pairs, within segments of genome called simple sequence repeats (SSRs) that consist of multiple copies of a short sequence (from one to several nucleotides), repeated in series.  SSRs are found in eukaryotes as well as prokaryotes, and variation in them occurs at frequencies up to a million-fold higher than the average bacterial mutation rate through a process of slipped stranded mispairing (SSM) by DNA polymerase during replication. The characterization of SSR length by standard sequencing methods is complicated by the appearance of length variation introduced during the sequencing process that does not accurately quantify lower-abundance repeat number variants in a population. Here we report a computational approach to correct for process-induced artifacts, validated for tetranucleotide repeats by use of synthetic constructs of fixed, known length. We apply this method to a laboratory culture ofHistophilus somni, prepared from a single colony, and demonstrate that the culture consists of populations of distinct sequence phase and read length variants at individual tetranucleotide SSR loci.Input requirements: Closed Genome - It is recommended that only organisms with closed genomes be the subject of the analyses described here. Mapping repetitive reads to to contigs of non-closed genomes may map to multiple locations, complicating tha analysis. Mapping CCS (circular consensus sequence) wiith repetitve sequence to closed genomes are guaranted to map to a single locus if sufficent unique flanking sequence is used to confim the unique mapping. Consequently, long CCS with high base quality are the most desirable input into this workflow. United States Department of Agriculture 5 2019 Gregory Harhay 2019.
