CEX-800
and CEX-1500 by Ultra-Lum crosslink DNA or RNA to
nitrocellulose, nylon or nylon-reinforced transfer membranes.
Studies show ultraviolet energy can be used as an alternate to oven baking
(normally for 2 hours at 80°C)
for the crosslinking process. UV
energy completes the process in seconds.
CEX-800 and CEX-1500 utilize a patented electronic ballast for
increased intensity, accuracy and shorter crosslinking time.
Proper
UV crosslinking shows enhanced transfer of DNA or RNA to a membrane when
receiving an optimal dose of UV energy.
All crosslinkers are designed to optimize UV energy, while ensuring
DNA/RNA membranes are consistently crosslinked. By use of an internal feedback system with the
microprocessor controlled, researchers have control over UV energy level,
exposure time and intensity. Additionally,
this control system automatically adjusts to variations in UV intensity
that occurs as the UV source ages, ensuring consistent crosslinking.
These
units operate in four selectable modes:
-
Automatic
optimal cross-link preset at 120,000 micro joules
-
Adjustable
energy programming from 0 – 999,900 micro joules
-
Automatic
time preset at 5 minutes
-
Adjustable
time programming from 0 – 999.9 minutes
Also
available is the magnetic ballast Thriftline
series. These lower-cost
models (without electronic ballasts) are built to the same high quality
standards as the CEX series. Both
types optimize bench space requirements while providing large internal
dimensions.
