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.

Does the increase of exosomal microRNAs reflect an activated immune system in melanoma?
Nina Koliha, Florian S. Dreyer , Jochen Dindorf , Andreas Bosio, Andreas S. Baur , and Stefan Wild

Cutaneous malignant melanoma is a form of skin cancer that accounts for 65% of skin cancer-related deaths. The incidence increases continuously, and while early detection leads to nearly 100% survival rates, the mortality raises to greater than 80% for patients with advanced disease.

A New Approach to Increase Yields and Improve Functionality of Recombinant Proteins
Antti Vasala, BioSilta Oy, Oulu, Finland

The ability to express and extract fully functional proteins in sufficient quantities from bacterial cultures is a prerequisite for many projects in which recombinant proteins are required for structural studies, functional characterization, as assay components or for other applications. However, low yield, poor solubility and lack of functionality are often associated with, what should be, a routine procedure.

Over-representation of Proteins Identified as Disease Biomarkers and their Relation to Post-Mortem Events
B. Orback, K. Kultima, M. Borén, M. Söderquist and K. Sköld

Tissue sampling is a major traumatic event that can have drastic effects within a very short timeframe at the molecular level resulting in loss of sample quality due to post sampling changes. It has recently been reported that the same proteins, regardless of tissue origin or species, are often found expressed differentially in various disease states, bringing into question the significance of these proteins as biomarkers.
