2012-03-09 · To characterize this unwinding reaction we have employed steady-state helicase assays, pre-steady-state rapid quench helicase assays, DNaseI footprinting, and electron microscopy. We conclude that UvrD binds initially to the junction compared with binding one of the blunt ends of the four-way junction to initiate unwinding and resolves the synthetic substrate into two double-stranded fork

Tth Argonaute: M0665 It is provided at 50X concentration and includes an amount sufficient for at least 500 LAMP reactions (0.5 µl per 25 µl LAMP reaction is recommended when monitoring reactions on most real time qPCR instruments). In other instruments, further dilution of the dye may be necessary (to a final concentration of 0.1-0.5X). For helicase aficionados, the subtle aspects of UvrD mechanism are intriguing. UvrD is known to load at single-stranded/ double-stranded junctions and, depending on its oligmeric state, translocate on single-stranded DNA as a monomer or unwind duplex DNA as a dimer.3 Therefore, the assembly state of UvrD as it pulls RNA polymerase backward is of Based on your Freezer Program type, you are trying to add a product to your cart that is either not allowed or not allowed with the existing contents of your cart.
