3D Cell Culture: mimicking real tissue
Application Note

Tecan Group Ltd.

Technological advances in the last couple of years have enabled 3D scaffolds to be engineered that offer a real proxy for the in vivo environment which can be easily and routinely used in a cell culture laboratory.

Alvetex Scaffold enables cells to develop natural, in vivo-like intercellular interactions, providing an ideal environment for real three-dimensional growth and nutrient exchange that is comparable to intra-capillary exchange in living tissues.

3D cell culture: a realistic and reproducible collagen-based environment
Application Note

Tecan Group

Researchers are increasingly turning to 3D cell culture techniques, due to the improved physiological relevance of the cellular environment. 3D cell cultures offer a more in vivo-like response to stimuli more closely resembling the behavior of animal models or the human body.

Optimized cell culture
Application Note

Tecan Group Ltd.

Culturing of various stable cell lines, including bacterial, yeast, hybridoma, insect and mammalian lines, and stem cells, is an important task in the pharmaceutical industry. The cells need to be maintained and expanded for use in cell-based assays, such as siRNA screening, ADME and high content screening, as well as for clone selection.

Forensic Investigations using Confocal Raman Imaging
Application Note

WHEATON

Confocal Raman Imaging is a very effective tool for forensic analysis as it provides information on the chemical composition.

General V3 Western Blotting Protocol
Application Note

Bio-Rad Laboratories

Western blotting is a very useful and widely adopted lab technique, but the traditional procedure can be long and tedious. Researchers can assess only whether a blot image is captured at the end of the long procedure and the quality of western blot data is sometimes challenged due to poor loading controls.

Avoiding Housekeeping Protein Detection Saturation
Application Note

Bio-Rad Laboratories

Reliable western blot data require detection of the target and loading control proteins in the linear dynamic range. Many published western blot images show saturated protein bands, indicating that they were not measured in the linear dynamic range. Quantitative analysis based on this type of data is not reliable.

Identification of the Site of the Octanoic Acid Post-Translational Modification in Human Ghrelin Using Electron Transfer Dissociation
Application Note

Washington University School of Medicine

ETD is a powerful fragmentation technique that has proved particularly useful for the determination of labile post-translational modifications of peptides and proteins. The technique has been used to determine the site-specific octanoylation of the peptide Ghrelin which could not be determined using Collision Induced Dissociation.

ESGRO-2i Medium: Inhibitor-Based Serum-free Medium for ES and iPS Cell Culture
Application Note

EMD Millipore

Defined serum-free and feeder-free culture of mouse embryonic stem (mES) cells holds many advantages over the classical serum-containing feeder-dependent culture methods, ranging from decreased lot-to-lot variations to ease of culture.

Dual-Glo Luciferase Reporter-Gene Assay on the SpectraMax M5, LMax II384 and Analyst GT Microplate Readers
Application Note

Molecular Devices

Reporter-gene assays are used to study eukaryotic gene expression. Dual genetic reporters are commonly used in transient transfections of cultured cells to minimize experimental variability. Recently, Promega introduced a Dual-Glo Lucoferase assay system which replaced the outdated ‘flash’ assays used previously. Ensuring both genetic reporters have different substrate requirements enables them to be detected using a single reaction mixture.
