LightyCycler® 96

An ideal combination of accuracy, temperature homogeneity, and reproducibility.


Maximize Well-to-Well Consistency through Innovative Optics
1. Equally excite all 96 wells.

Equal excitation of all wells—particularly in wells at the plate edges—is difficult to achieve in a rectangular plate excited by a round light source. Some suppliers’ systems scan a lower-intensity LED across the plate to excite all wells. Others rely on master mixes containing a passive reference dye that attempts to compensate for these “edge effects.”

The Roche Solution:

Equally excite all wells at the same time through the system’s high-intensity LED, which simultaneously transmits equal amount of light through the first set of 96 optical fibers.

2. Simultaneously capture the signal from 96 wells.

Simultaneous capture of signals from all 96 wells is equally essential to maximize well-to-well consistency and avoid sample bias. Some suppliers’ systems rely on a scanning head that reads the 96 wells sequentially, not simultaneously, introducing a source of well-to-well inconsistency because of the time lag in data acquisition.

The Roche Solution:

Simultaneously capture the signal of all 96 wells through the second set of 96 optical fibers, each of which is positioned directly over its own well.

3. Maintain temperature homogeneity across the plate.

Temperature inconsistencies across the plate can produce differences in cycling temperatures or “hot spots,” and thus disparate results, in different wells.

Generate Data You Can Trust
Insist on a high-performance system that generates accurate, publication-ready results you can trust. Take full advantage of the LightCycler® 96 System’s innovative optics and highly homogeneous thermal cycling conditions (Figure A) to produce the precise, reproducible data you need (Figure B) to achieve your research and personal goals.

Figure A. The LightCycler® 96 System generates reproducible, efficient, and consistent results. The Parvo B19 gene was amplified in 11 serial 1:2 dilutions of plasmid DNA (4 replicates each), from 500,000 copies to 244 copies, and detected with a hydrolysis probe assay. Results show a clear separation of the different dilutions, demonstrating that the system can efficiently discriminate between 2-fold differences, even down to 244 copies. Also, the very close Cq values (ΔCq < 0.2) of the replicates of a given dilution provide evidence for the reproducibility of the LightCycler® 96 System.

Figure B. Homogeneous and uniform temperature across the block. Real-time PCR was performed using 3 pg of human DNA in each of the 96 block positions. (a) A 71-bp amplicon of the beta-globingene was amplified using hydrolysis probe detection. (b) The reaction product was also subjected to melting curve analysis. Low variation Cq values (Cq range =0.33 and SD=0.06) and overlapping melt curves of the amplicon (Tm range of 0.31°C and SD=0.31) in each of the 96 positions demonstrate temperature homogeneity and equal treatment of all samples - independent of block position.
