    Conditional Human BRD4 Knock-In Transgenic Mouse Genotyping and Protein Isoform Detection
    Authors:  Michael Paul Lewis, Shwu-Yuan Wu and Cheng-Ming Chiang, date: 04/05/2022, view: 1086, Q&A: 0

    Bromodomain-containing protein 4 (BRD4) is an acetyl-lysine reader protein and transcriptional regulator implicated in chromatin dynamics and cancer development. Several BRD4 isoforms have been detected in humans with the long isoform (BRD4-L,

    Reference-free Association Mapping from Sequencing Reads Using k-mers
    Authors:  Zakaria Mehrab, Jaiaid Mobin, Ibrahim Asadullah Tahmid, Lior Pachter and Atif Rahman, date: 11/05/2020, view: 4033, Q&A: 0
    Association mapping is the process of linking phenotypes with genotypes. In genome wide association studies (GWAS), individuals are first genotyped using microarrays or by aligning sequenced reads to reference genomes. However, both these approaches ...
    Methylation-sensitive Amplified Polymorphism as a Tool to Analyze Wild Potato Hybrids
    Authors:  Nicolás Cara, Carlos F. Marfil, María V. Bertoldi and Ricardo W. Masuelli, date: 07/05/2020, view: 3386, Q&A: 0
    Methylation-Sensitive Amplification Polymorphism (MSAP) is a versatile marker for analyzing DNA methylation patterns in non-model species. The implementation of this technique does not require a reference genome and makes it possible to determine ...
    Using Seed Chipping to Genotype Maize Kernels
    Authors:  Alison M. Mills, Lindy A. Allsman, Sareen Leon and Carolyn G. Rasmussen, date: 03/20/2020, view: 3696, Q&A: 0
    Zea mays (maize) is an important model organism for studying monocot growth and development. Genotyping maize in the greenhouse or field can be time consuming and costly. Here, we describe a method to remove or chip a small amount of the ...
    Using indCAPS to Detect CRISPR/Cas9 Induced Mutations
    Authors:  Charles Hodgens, Zachary L. Nimchuk and Joseph J. Kieber, date: 09/20/2019, view: 3054, Q&A: 0
    Cleaved amplified polymorphic sequences (CAPS) assays are useful tools for detecting small mutations such as single nucleotide polymorphisms (SNPs) or insertion/deletions (indels) present in an amplified DNA fragment. A mutation that disrupts or ...
    Genotyping of the OATP1B1 c. 521 T>C Polymorphism from the Formalin-Fixed Paraffin-Embedded (FFPE) Tissue Specimens: An Optimized Protocol
    Authors:  Alexandra R Crowe, Jonathan Miller and Wei Yue, date: 08/20/2019, view: 3046, Q&A: 0
    Organic anion transporting polypeptide (OATP) 1B1 is a liver-specific transport protein that plays an important role in hepatic drug disposition. It transports many drugs from the blood into the liver, including lipid-lowering statins. The c. 521 ...
    A High-throughput qPCR-based Method to Genotype the SOD1G93A Mouse Model for Relative Copy Number
    Authors:  Valerie R. Tassinari and Fernando G. Vieira, date: 06/20/2019, view: 5500, Q&A: 0
    The most commonly used mouse model in ALS preclinical research expresses multiple copies of the human SOD1 (G93A) transgene. During the course of breeding, successive generations of mice can lose copies of the transgene. Because shorter lifespan of ...
    Growing and Pollinating Maize
    Authors:  Sarah Hake and China Lunde, date: 05/05/2018, view: 5028, Q&A: 0
    Corn, also known as maize, has been a model organism for genetics since the 1900’s due to the ease of pollinations, large chromosomes and the prominent kernel and leaf traits with simple inheritance (Candela and Hake, 2008). It requires considerable ...
    Identification of Insertion Site by RESDA-PCR in Chlamydomonas Mutants Generated by AphVIII Random Insertional Mutagenesis
    Authors:  Fantao Kong and Yonghua Li-Beisson, date: 02/05/2018, view: 7094, Q&A: 0
    Chlamydomonas reinhardtii is frequently used as a model organism to study fundamental processes in photosynthesis, metabolism, and flagellar biology. Versatile tool boxes have been developed for this alga (Fuhrmann et al., 1999; ...
    Detection of Pathogens and Ampicillin-resistance Genes Using Multiplex Padlock Probes
    Authors:  Rick Conzemius and Ivan Barišić, date: 08/20/2017, view: 7891, Q&A: 0
    Diagnostic assays for pathogen identification and characterization are limited either by the number of simultaneously detectable targets, which rely on multiplexing methods, or by time constraints due to cultivation-based techniques. We recently ...
