  • Small RNA - FlashPAGE

    Hi Everyone,

    Has anyone tried using the FlashPAGE system to do library size selection from a finished small RNA library? Using the SOLiD protocol this would mean recovering the 105-150bp size range. Just wondering about the time settings and any helpful hints.

    Many Thanks,
    Richard

    It is typically hard to calibrate flashpage to give you the tight cut-off needed for the particular size range you need. I am assuming you want to purify away the adaptor only products from the products containing the RNA sequences of interest?

    This can be done, however the instrument wasn't really designed to run for extended periods of time and salt depletion can cause your power supply to conk out if it cannot handle very low mA readings. Otherwise, flashpage is a wonderful tool.

      Isn't Flashpage designed for separating single stranded nucleic acid? Would the ds DNA library run safe and sound through the gel?

        FlashPAGE gels are denaturing conditions and is indeed designed for single-stranded RNA, so your DNA would probably not stay double-stranded.

          Advanced Tools Transforming the Field of Cytogenomics
          by seqadmin


          At the intersection of cytogenetics and genomics lies the exciting field of cytogenomics. It focuses on studying chromosomes at a molecular scale, involving techniques that analyze either the whole genome or particular DNA sequences to examine variations in structure and behavior at the chromosomal or subchromosomal level. By integrating cytogenetic techniques with genomic analysis, researchers can effectively investigate chromosomal abnormalities related to diseases, particularly...

          How RNA-Seq is Transforming Cancer Studies
          by seqadmin



          Cancer research has been transformed through numerous molecular techniques, with RNA sequencing (RNA-seq) playing a crucial role in understanding the complexity of the disease. Maša Ivin, Ph.D., Scientific Writer at Lexogen, and Yvonne Goepel Ph.D., Product Manager at Lexogen, remarked that “The high-throughput nature of RNA-seq allows for rapid profiling and deep exploration of the transcriptome.” They emphasized its indispensable role in cancer research, aiding in biomarker...
