Advances in technology are continually improving scientists’ ability to identify and analyze trace amounts of DNA and RNA. Spectronics’ new high-quality, inexpensive Select XLE-Series UV crosslinker makes this analysis possible with far greater speed, sensitivity and accuracy than conventional methods. The crosslinker covalently binds nucleic acids to membranes in fewer than 30 s. It has true-UV-monitoring circuitry that safeguards test results from washouts, even when the tubes age. It is suitable for eliminating PCR contamination, nicking ethidium bromide-stained DNA in agarose gels, gene mapping for creating cleavage inhibiting thymine dimmers, RecA mutation screening in E.coli, UV sterilization, among others.
