capillary electrophoresis-laser-induced fluorescence

A technique which combines the highly efficient separation capacity of capillary electrophoresis and the affinity and specificity of antibody and antigen binding with the high sensitivity of laser-induced fluorescence.
 
Applications
Simultaneous immunoassays of multiple analytes in biologic fluids—e.g., to screen urine for drugs of abuse, such as morphine, heroin, codeine metabolites, PCP, THC (a marijuana metabolite) and benzoylecgonine (a cocaine metabolite).

Hence, the chemical cleavage yields a fluorescent fragment at the 5' end, whereas the other cleavage product (3' end) is not detectable by CE-LIF.
The present work demonstrates the precise estimation of molecular size and yield of CMC cleavage products by CE-LIF and exploits the efficient separation of ssDNA, demonstrating the fast analysis, the quantitative detection, and the small sample requirements of this technology.
DNA PURIFICATION, AMPLIFICATION, AND VALIDATION OF CE-LIF ASSAY
The CE-LIF assay described here was developed to analyze the MTHFR C677T mutation in the clinical setting but also to genotype large populations as part of prospective studies based on stored samples.
Signals from 15 of the 30 samples could be detected by CE-LIF after the single-step PCR protocol (Fig.
