Please feel free to Contact Us to discuss your projects. Thorough documentation of all steps is provided, including SDS-PAGE and Western Blot data.Ĭreative Proteomics also provide the following bioinformatics services in Membrane Protein Identification: Functional annotation and enrichment analysis Clustering analysis Network analysis Statistical analysis If necessary, buffer and detergent optimization is included in the service package to deliver proteins of optimal stability and activity. Purification conditions are optimized in small scale, and upscaling can be done up to mg amounts depending on the protein of interest. protein crystallization experiments or functional binding assays, a second or third purification step can be performed, using, for example, anion or cation exchange chromatography or gel filtration. To obtain highly pure, homogeneous protein fractions suitable for e.g.

Further purification steps for crystallization-ready, homogeneous protein fractions.

Thorough documentation of all steps is provided, including SDS-PAGE and Western Blot data. Purification conditions are optimized in small scale, and upscaling can be done up to mg amounts, depending on the protein of interest. Purification using other tags is available upon request. For membrane proteins, we recommend to use the Rho1D4 system. Purification of proteins fused to tags like His, GST, or Strep tags is performed using our high-quality affinity purification matrices.

Affinity purification using His, Rho1D4, GST, or strep tags.

If proteins are expressed as inclusion bodied, resolubilization and refolding is done, including a screen for the optimal detergent and buffer conditions. Detergents are optimized for protein stability during extraction and purification steps. In the case of membrane or membrane-attached proteins, detergents are required to extract the proteins from bacterial or eukaryotic membrane. If applicable, established activity assays can be performed to correlate stability and activity status. For soluble and membrane proteins, the optimal buffer conditions for stability are determined using differential scanning fluorimetry (DSF).

Buffer and detergent screening for solubilization and purification.Depending on the expression host or expression vector used, proteins need to be purified from the cytoplasm, the (bacterial) periplasm, or cell culture supernatants, and we have established optimized protocols for each of these applications. Purification from cytoplasm, periplasm, or cell culture supernatants.Our membrane protein service offering includes:

Ion channels represent another group of important membrane protein drug targets and account for the activity of 10% of the currently marketed drugs.ĭespite their importance, membrane receptors are notoriously difficult to prepare in pure, correctly-folded form in sufficient quantity for drug discovery purposes.

The G protein-coupled receptors (GPCRs) are the largest, most versatile group of membrane receptors and also the most pharmaceutically important, accounting for over 50% of all human drug targets and acting as therapeutic targets for a wide range of disease conditions including cancer, cardiovascular, metabolic, CNS and inflammatory diseases. Membrane proteins account for up to two thirds of known drugable target, highlighting their critical pharmaceutical importance. Membrane proteins such as receptors and ion channels are key regulators of cellular function.
