Transparent Spotting Guide may be used with plates up to 20 x 20 cm. The guide rests above the surface of the plate without contacting the adsorbent layer, avoiding damage to the layer. It accurately positions micropipettes and syringes, even when the plate is removed for drying between applications. The metric scale on the Spotting Guide facilitates reading of Rf values. Standard area circles of 3 to 255 mm2 aid in estimating spot sizes.
Purified fractions of DNA and RNA are analyzed by agarose gel electrophoresis.
