Methylarginine-specific antibodies are protected under US Patent 6,699,673.

MSK1/MSK2 Proteins

Mitogen-and-Stress-Activated Protein Kinase 1 and 2 (MSK1, MSK2) are unique nuclear serine/threonine protein kinases containing two kinase domains within a single polypeptide. These kinases are believed to mediate signal transduction in the inflammatory response and regulate cellular proliferation and differentiation. MSK1 and MSK2 are activated by the MAPK/ERK pathway (mitogen/growth factor signaling) or SAPK2/p38 pathway (stress/oxidation signaling) and activate transcription factors ATF-1 CREB. Protected under US Patent 7,122,360 and related foreign equivalents.

Nus-Tag® Fusion System

The NusA protein is an E. coli protein that was identified by solubility modeling as having a very high probability of being soluble when expressed in E. coli. When fused to heterologous proteins, NusA has been shown to increase the solubility of target proteins in E. coli, thus circumventing the formation of inclusion bodies common to heterologous protein expression in E. coli. Nus-Tag® Vectors have been developed by EMD Millipore to allow cloning and high-level expression of the NusA protein fused to a protein of interest. Protected under US Patents 5,989,868 and 6,207,420.

The pTriEx™ Expression Vectors are triple host vectors capable of expressing an inserted protein coding DNA sequence in any of three distinct host systems. The vectors include three promoters, β-actin or CMV (vertebrate), T7lac (bacterial), and p10 (insect), such that the protein coding sequence can be cloned into the vector once and then allow for protein expression in all three types of host cells. The arrangement and selection of the promoters contribute to expression characteristics in all three host systems that are comparable to single host expression vectors. Protected under US Patent 6,589,783.

ReNcell Stem Cell Lines

ReNcell VM and ReNcell CX are two well-established neural stem cell lines derived from developing human brains. ReNcell VM and CX cells are generated from the ventral mesencephalon and cortical regions of the brain, respectively, and transduced with the myc transcription factor. Both cell lines offer phenotype and genotype stability, in addition to the multipotential neuronal differentiation capacity, over long-term culture. These cells are sold for a six-month evaluation period and require a commercial license from EMD Millipore for any use beyond this initial evaluation period.

SGK Activity Assays

Serum and glucocorticoid-induced protein kinase (SGK) is a class of serine/threonine protein kinases induced following cellular exposure to serum or glucocorticoids. SGK is also induced in response to other stimuli, such as follicle stimulating hormone (FSH), induced extracellular osmolarity, and transfection of mammary epithelial cells with p53. SGK is activated by IGF-1 or oxidative stress via the phosphatidylinositol (PI)-3-kinase pathway. Once activated, SGK preferentially inactivates GSK3 via phosphorylation. Protected under US Patent 7,083,511.
