Thumbnail Filmstrip of Ultra Purity Alpha Cotton Dried Blood Spot Card, 2x3in, Guthrie Test Optimized, Research Only, 50/Pk Images
Featuring high purity alpha cotton linter absorbent filter paper specifically formulated to yield a stable DNA, RNA and protein biomarker matrix for quantitative analysis, this advanced cellulose paper delivers exceptional performance for dried blood spot applications. Surface texture, absorption rate and formation have been optimized for the Guthrie test while maintaining highly uniform formation and freedom from density irregularities. The 2x3 inch format with 180g/m² basis weight and 0.44-0.47mm caliper thickness provides consistent specimen collection for bioanalysis protocols requiring reliable DNA/RNA extraction and protein biomarker analysis.
Key Ultra Purity Cotton Linter Characteristics
- High purity alpha cotton linter construction eliminates contamination sources and maintains biomarker stability
- Punches cleanly demonstrating minimal extraneous fibers for precise disc preparation and reduced analytical interference
- Manufacturing performed with RO water filtration system ensuring ultra-clean production environment for research applications
- Excellent lot-to-lot reproducibility with material chemistries verified against quality standards using GC techniques
- Migration distance of 120-135mm/10 min optimizes blood dispersion while maintaining uniform analyte distribution across the matrix
Key Construction and Performance Characteristics
- Purity, formation, basis weight and caliper specifications offer highly reproducible platform for direct elution techniques
- Material holds embossing with or without heat set and converts well for incorporation into diagnostic devices
- Meets or exceeds results obtained using conventional manual extraction methodology in comparison to known competitive commercial equivalents
- Uniform screen & felt sides with consistent density MD/CD delivers reliable sample distribution across the entire card surface
- Nonsterile research-grade specification accommodates laboratory validation protocols without clinical regulatory constraints
LE-DBSV1-001 cards excel in bioanalysis applications such as the collection of blood drops typical of the Guthrie test, a microbiological assay for the presence of phenylalanine, phenylpyruvate, and phenyllactate in blood or urine. The Guthrie test is used to screen newborn infants for phenylketonuria (PKU), making these cards essential for metabolic disorder research and validation studies. Certificate of Compliance and Certificate of Analysis provided with shipments ensures documented quality assurance for your research protocols, while the optimized cellulose matrix delivers superior biomarker preservation and extraction efficiency compared to conventional filter papers.
