Roti®Nylon Plus Reprobe is a positively charged nylon membrane offered as ready-cut sheets for nucleic acid blotting. Each sheet measures 30,5 × 30,5 cm and has a pore size of 0,45 µm, matching typical gel and transfer formats used in Southern and Northern blot work. The pack contains five sheets, so multiple transfers can be prepared without cutting from a roll. This format supports transfer of nucleic acids to membranes in molecular biology laboratories that prefer pre-sized pieces. Roti®Nylon Plus Reprobe from manufacturer Carl ROTH is intended for blotting applications in the Southern and Northern range. The positively charged nylon membrane and defined 0,45 µm pore size fit standard handling steps during capillary or other common transfer methods. Square 30,5 cm sheets simplify layout in transfer stacks and reduce preparation time when gel dimensions are known in advance. Five sheets per pack provide a convenient stock for repeated nucleic acid transfer experiments under routine laboratory conditions.
