Electrophoresis specialist Cleaver Scientific now offers researchers and scientists a wider choice and greater flexibility thanks to the introduction of a new range of semi-dry blotting products. Typically, most semi-dry blotters are primarily designed to blot thin protein gels up to 20 x 20 cm in size. The companys blotters, however, allow users to blot larger, thicker gel sizes and also provide for Western blotting of proteins and gels up to 33 x 45 cm. They provide faster transfer times and low buffer volumes for improved economy in the laboratory, and they can also be used for Southern blotting (of DNA) and Northern blotting (of RNA).
