Catalent Develops New Decorin Molecule Form, Strikes Deal With Euclid

Catalent Pharma Solutions, a leading provider of advanced technologies and outsourced development and clinical services to the global pharmaceutical and biotechnology industry, has announced the development of the Galacorin™ molecule, a proprietary form of the decorin molecule.

Catalent Develops New Decorin Molecule Form, Strikes Deal With Euclid

Catalent combined its proprietary GPEx® gene expression technology, Triplet-FixTM codon optimization technology and advanced scientific capabilities to greatly improve production and secretion of the GalacorinTM molecule in CHO cells. In addition, Catalent has developed a full cGMP production process for the GalacorinTM molecule.

Catalent has reached an agreement to provide the GalacorinTM molecule to Euclid Systems of Herndon, Virginia for an ophthalmic clinical trial. Financial terms of the agreement have not been disclosed. Additionally, Catalent is in the process of seeking partners for other indications.

Catalent’s proprietary GPEx® method of cell line engineering generates high-expressing, genetically stable cells for all mammalian cell types. Antibiotic selection is not needed as part of the procedure; multiple gene constructs can be added individually, at different gene ratios without any requirement for antibiotic resistance markers. The method allows re-production of cellular pathways within mammalian cell types as well as the ability to easily add protein processing enzymes to an already established cell line. Using conventional gene insertion and expression techniques, developing a stable biosimilar production cell line for a target protein can take as long as 18 months. Catalent’s GPEx® technology can overcome the inefficiencies of conventional systems and deliver a stable production cell line for target proteins in as little as 4.5 months.

LC Sciences First miRNA Microarray Service Provider to Offer Plant MicroRNA Database (PMRD) Probe Content

Taking full advantage of its flexible µParaflo® Biochip Technology, Houston based LC Sciences today announced immediate availability of probe content from the newly created Plant MicroRNA Database (PMRD) for their microRNA (miRNA) microarray customers . This announcement comes immediately following a publication in Nucleic Acids Researchintroducing the public database 1 . The PMRD integrates available plant miRNA data deposited in other public databases, gleaned from the recent literature, and data generated by the database organizers. It is freely available at http://bioinformatics.cau.edu.cn/PMRD.

LC Sciences miRNA microarrays make use of a microfluidics on-chip synthesis platform, termed µParaflo®, versus a traditional spotted array based on pre-synthesized oligonucleotides. This on-chip synthesis platform means made-to-order microarrays can be produced, delivering the most up-to-date research tools to researchers; in this case, the PMRD content.

In total, there are 8433 miRNAs collected from 121 plant species in PMRD, including model plants and major crops such as Arabidopsis, rice, wheat, soybean, maize, sorghum, barley, etc. For Arabidopsis, rice, poplar, soybean, cotton, medicago and maize, the possible target genes for each miRNA with a predicted interaction site are included in the database. This represents a significant increase in content vs plant miRNA microarrays based solely on the miRBase content.

The public miRBase sequence database 2 serves as the primary probe content for many commercially available miRNA profiling microarrays (http://microrna.sanger.ac.uk/sequences/). Detection of miRNAs using a microarray offers the opportunity for genome-wide miRNA expression profiling by examining all known miRNA transcripts in a single experiment. However, in a rapidly evolving field such as miRNA research, it is important to have a flexible system that can keep up with all the newly discovered and predicted sequences. Pre-spotted glass slide arrays immediately go out of date whenever new miRNA database versions are released. LC Sciences’ microarrays ensure scientists have the most complete picture of miRNAs expressed in their experimental samples.
