Dried blood spot, ultra purity cotton paper card 3x4 inch, research only, 50 pack
These blotter paper grades are highly consistent general purpose electrophoresis blotters. Smooth surface, bright white pure cotton cellulose paper. Material is manufactured from carefully selected, USA sourced pure alpha cellulose fiber which is fully oxygen bleached and resin free. The material is free of additives which can interfere with the membrane indication and transfer process. It's smooth surface promotes clean transfers and blots. The fiber processing is designed to allow both small highly-fibrillated material to blend with longer less processed fiber for a high density, highly absorbent and very rapid migration. The even density and high grade formation yields a very consistent and reproducible migration in both MD and CD. Naturally hydrophilic with no additional surfactants or additives necessary to yield high performance surface absorption rates and migration speeds.
In addition to electrophoresis pads, Dried Blood Spot pads, which are similar in composition are available for life sciences (research only) projects. This material is amongst the more pure cotton linter pad on the market with no additives or bleaches.
