This material was the stationary phase in the first 2D form of chromatography, which was used to sequence gramicidin S and insulin. MicroPADs are formed by patterning this material, then immersing it in periodate (“per-EYE-oh-date”) or ammonia to shrink it for use in POC microfluidics. Qualitative grades of this material offered by Whatman (10[1])can be directly used in gravimetric analysis (10[1])because (10[1])they produce little ash. Electrophoresis has largely replaced the use of stacks of this material to lift analytes onto a nylon or PVDF (10[1])membrane with capillary (10[1])action. (10[1])Discs (10[1])of this material (10[1])are used in Buchner funnels (10[2]-5[1])with a perforated (10[2])plate. (10[4])The Southern (10[1])blot (-5[2])is named for using the “blotting” form of this material, which separated dyes (10[1])in the first chromatograms. (10[1])For 10 points, name this material formed from cellulose pressed into sheets. (10[1])■END■ (10[2]0[2])
