Shipping Delays

UPS and FedEx are experiencing significant weather delays across the U.S. To maintain the high performance and reliability our customers expect, many orders received on or after February 10th may have been delayed for shipping. As inclement weather subsides and we resume shipping, you could expect a 1-3 day delay in transit. We apologize for any inconvenience this may cause.

An Introduction to Capillary Electrophoresis

Capillary electrophoresis is a method for separating and identifying fragments of fluorescently-labeled DNA by passing them through very thin polymer-filled capillaries. The use of capillaries instead of a conventional slab gel makes it possible to apply a much stronger electric field, resulting in faster separation and higher throughput. The process features single-base resolution and requires small sample quantities. 

Fluorescently labeled DNA samples are prepared for electrophoresis and loaded into the CE instrument. The capillary array is filled with polymer and placed into the sample wells. When the capillary array enters the wells, an electric current is formed, and the DNA fragments are moved electrokinetically into the capillaries. Next, the ends of the capillary array are inserted into the cathode and anode buffer. The instrument applies a specific voltage and temperature to control sample migration through the capillary array. The fragments are separated by size, with the smallest fragments moving fastest.

The final step is sample detection. As the fluorescently labeled fragments move past the detection window, a laser excites the fluorescent dyes. The emitted light is spectrally separated and recorded by a CCD camera. The CCD camera records the fluorescent signature of each fragment, as well as the elapsed time for the fragment to migrate through the polymer. The raw data is sent to the collection software in the form of a peak and is now ready for analysis.

Applications include STR analysis and Sanger Sequencing, as well as many other everyday functions of both forensic, academic and clinical research laboratories.
