LabExact® Dried Blood Spot Cellulose Paper is a high purity alpha cotton linter absorbent filter paper specifically formulated to yield a stable DNA, RNA and protein biomarker matrix for quantitative analysis and optimized for the Guthrie test.

• The formation is highly uniform and free from density irregularities with consistent basis weight and caliper to offer a highly reproducible platform for direct elution techniques
• Meets or exceeds results obtained using conventional manual extraction methodology in comparison to known competitive commercial equivalents
• Most notably the Guthrie test is used to screen newborn infants for phenylketonuria (PKU)
• Manufactured in the USA

Ideally suited as a specimen collection media for 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.

Basis weight: 180 g/m²
Caliper thickness: 0.44 to 0.47 mm
Migration distance: 120 to 135 mm/10 min
