Aug 18 Webinar: Finding Data for your Research Organism: Plants and RNA-Seq data

Aug 18 Webinar: Finding Data for your Research Organism: Plants and RNA-Seq data

Join us on August 18, 2021 at 12PM eastern time for the second webinar on finding data for your non-model research organism. In this webinar, you will learn how to use NCBI’s web resources to get data for a plant species, the black cottonwood. You will see how to find, access, and analyze gene and sequence data from Datasets and other NCBI web resources, as well as sample metadata and gene expression RNA-Seq data from SRA and the SRA Run Selector. You will also see an example that highlights how to use and analyze these data in a typical workflow set up in a Jupyter notebook that uses the NCBI next-gen aligner Magic-BLAST to get relative gene expression levels across samples.

  • Date and time: Wed, August 18, 2021 12:00 PM – 12:45 PM EDT
  • Register

After registering, you will receive a confirmation email with information about attending the webinar. A few days after the live presentation, you can view the recording on the NCBI webinars playlist on the NLM YouTube channel. You can learn about future webinars on the Webinars and Courses page.

New feature added to Primer-BLAST to better design primers for expression assays

We’ve added a new feature (Max 3′ match), shown in Figure 1, to Primer-BLAST that limits the length of 3′ exon matches when designing exon-exon spanning primers. This makes it less likely that primers specifically designed to amplify transcripts will also amplify genomic DNA contamination in expression assays.

Figure 1. The new “Max 3′ match” option that limits the size of the 3′ match for exon-exon junction primers. This option helps avoid primers that may also produce product from genomic DNA. Continue reading “New feature added to Primer-BLAST to better design primers for expression assays” →
