    Cytomegalovirus DNA detection in Guthrie cards: a powerful ...

    DNA extraction from Guthrie cards is well possible (Schneeberger et al. ); an improved processing method for human blood samples was published by Makowski et al. (). Filter papers.
  • A Simple Automated DNA Extraction Method for Dried Blood ... This study evaluated two deoxyribonucleic acid (DNA) extraction methods for Guthrie card bloodspots. Our water-based extraction technique was compared with a commercial kit (GFX extraction system). In contrast to our nondenaturing method, the GFX system utilizes chaotropes to extract DNA. Extracted DNA is subsequently.
  • Population-Based Screening for Rare Mutations: High ... - Nature The GFX extraction kit provides a useful means to standardize Guthrie card DNA extraction and was adaptable for limited sample (i.e., extraction of a 3 mm punch yields 20 amplifications). Expand.
  • A simple method for extraction of DNA from Guthrie cards To determine the population-based frequency of a rare mutation (the ins2 mutation in the surfactant protein B gene), we developed high-throughput techniques to extract reliably and rapidly.
      • Efficient extraction of DNA from Guthrie cards is desirable to fully utilize this valuable resource.
    “Guthrie cards,” paper cards with dried blood collected from all newborns for neonatal screening as mandated by state laws, 1 have long been recognized as a valuable resource for population-based and epidemiological studies. 2–5 Deoxyribonucleic acid (DNA) contained in the blood spots is quite stable and is useful decades after collection.
      We describe a rapid, simple and inexpensive method for the isolation of DNA from blood clots suited for use in PCR. Our method is based on the.
    Purified DNA was quantified (left panel), and DNA profiles of saliva dilutions was performed (AmpFIstr® SGMplus®, right panel). 10 µl 1µl µl 09/ Automated protocols based on the workflow at the right are available for forensic sample types. Small-volume blood or saliva samples Up to µl blood or saliva FTA and Guthrie Cards.
      “Guthrie cards” are widely used in many types of tests, including chemical, serological, and genetic applications [3].
    Amplification of DNA from whole blood collected on Guthrie card filter paper presents considerable technical obstacles due to the presence of natural PCR inhibitors (protein, heavy metals, heme, and heme degradation products) and low copy number of genomic.

    Maximizing Deoxyribonucleic Acid Yield from Dried Blood Spots

    Guthrie card bloodspots have proven particu­ larly helpful for the biochemical detection of elevated immunoreactive trypsinogen concen­ tration (a CF marker) Although it is possible to extract sufficient DNA from Guthrie cards for Southern blot analysis directly,22 this pro­ cedure has limited application due to large.


    Cystic Fibrosis: Molecular Approaches to Diagnosis*

    In a preliminary study, we showed that a method for the extraction of CMV DNA from dried blood spots (DBS) on filter paper (Guthrie card) followed by nested polymerase chain reaction (PCR) amplification allows the diagnosis of congenital CMV infection (Barbi et al., ).

    • DBS on a filter paper collection card, commonly called the “Guthrie card”, has been routinely used for population-based newborn screening. In an effort to develop primary DNA-based newborn screening tests, we developed a simple high-throughput DNA extraction method for the use of DBS in an automation system.
