On-chip quantification of miRNA using digital droplet PCR
Q. Cai1, R.S. Wiederkehr1, B. Jones1, B. Majeed1, T. Stakenborg1, P. Fiorini1, L. Lagae1, M Tsukuda2, T. Matsuno2, I. Yamashita2

miRNAs have a great potential in diagnostics. Hence, automated profiling of miRNAs are of great interest. In-house technology show that it is possible to implement a multiplexing assay for miRNAs on a microfluidic chip using digital droplet PCR.

High-throughput analysis of protein formulations by DLS
Sophia Kenrick and Daniel Some

High-throughput analysis of protein formulations by Dynamic Light Scattering (DLS): thermal stability, colloidal stability and a thermal anomaly in the colloidal stability parameter D1

Digital microphotographic atlas of the adult zebrafish cerebellum
Kristen Lee, Megan Landy, Ashton Cline, Christopher Corbo, and Zoltan Fulop

Sagittal, coronal and horizontal, one micron thick plastic (semithin) sections of adult zebrafish (Danio rerio) brain were photographed in 40X. The sections were then photomontaged together using in Adobe Photoshop CS5 Extended Version 12.0 to make the photographic atlas.

Microwave Assisted Green Synthesis of Aspirin From Over The Counter Pain Creams
Annie E. Dineen, Jodie T. Wasacz

A successful microwave synthesis of methyl salicylate to aspirin using green catalysts from over the counter pain creams. The process was also prepared and tested in an undergraduate organic chemistry lab.

Analytical Pipetting of Serum
John Thomas Bradshaw, PhD, Leah Flumerfelt, Richard H. Curtis, PhD, Rachel Parshley

Many types of chemical and biological analyses are based upon analytical techniques involving accurate delivery of liquid components. Pipetting tools have become commonplace especially in many biological and pharmaceutical laboratories. While these tools are familiar to many, their operational differences when pipetting different types of solutions are often over-looked.

Droplet Microfluidics for 3D Epithelial Cell Culture
Monika Dolega (Pyzalska), Xavier Gidrol, Nathalie Picollet-D’hahan

The challenge facing 3D cell culture today is to adapt current models to a systems biology approach - in particular, to enable RNA interference-based screens to study the effects of the microenvironment on cellular function.

Rapid analysis of 3D tumour spheroids in soft agar and on ultra-low attachment plates using a laser scanning imaging system
Anne F Hammerstein, Diana Caracino, and Paul Wylie

The requirement for better in-vitro models that are compatible with high-throughput screening campaigns has led to the development of 3D cell cultures models, especially muliticellular spheroids, which retain many of the morphological and genetic traits of tumours.
Here we describe the formation of such spheroids by two methods: on ultra-low attachment plates and in semi-solid agarose. Both methods are compatible with 96- and 384-well microplate formats.

Combining low and high volume liquid handling capabilities for ADME screening
Joby Jenkins, Kevin Moore, Stephen Fowler, Pascal Schenk

In this study we demonstrate the integration of two liquid handlers to extend the volume dispensing range creating low-volume assay-ready plates with high accuracy and precision. This was then successfully applied to a CYP inhibition assay.
