Low-cost UV crosslinker speeds up DNA research


High-quality but inexpensive ultraviolet crosslinker is designed to help identify and analyze trace amounts of DNA/RNA with far greater sensitivity, accuracy and speed than with conventional analysis. The UV crosslinker covalently binds nucleic acids to membranes in under 30 seconds, which the manufacturer says is 240 times faster than vacuum-oven baking. Its UV-monitoring circuitry safeguards valuable test results from washouts, even when the tubes age. The instrument is suitable for eliminating PCR contamination, nicking ethidium-bromide-stained DNA in agarose gels, gene mapping for creating cleavage-inhibiting thymine dimers, RecA mutation screening in Ecoli, UV sterilization and miscellaneous UV-dosage applications.
